parts; Broken tools and debris of workpieces may fly out; The chips may fly out; The coolant may spray out of the machine; Noises may be released;

The operator is not allowed to open the protective door with the power on. Otherwise, the safety device may not work properly to lead to injuries.

When needing to open the protective door with the power off, please entrust the maintenance staff. Operations with inadequate expertise may lead to injuries due to unexpected movement of the machine.

The modification of the parameters should be conducted by the staff with adequate expertise. In some cases the interlock system may not work when modifying parameters, and thus the dangers of injuries may increase. The availability of the interlocking system should be confirmed when modifying parameters.

g) Warnings on Fire

Danger

Do not use the coolant with low flash point (2nd oil family with flash point lower than �). Otherwise fire may happen. Even the coolant of 3rd oil family (with a flashpoint between 70� and 200�) and 4th oil family (with a flash point higher than 250�) may be ignited, so it is necessary to pay enough attention to the state and method of use, such as controlling the production of smoke.

Flammable and incendiary materials such as dilute agent, gasoline, paper, wood, cloth, fiber, and aerosol sprays are not allowed around or near the machine (including power cables and connection cables). These materials may be iginted by the heat of the chips and sparks.

Warning

Guard against fire when using flammable workpieces. They should be processed with appropriate tools on appropriate

conditions. On the processing conditions that are not suitable with worn tools may cause fire due to heat in cutting. Moreover, the sparks caused by broken tools that splash onto the chip may cause fire. Please refer to the information provided by the tool manufacturers to perform processing with appropriate tools and on appropriate conditions.

The machine must be stopped when the tool is damaged. Otherwise, the residual tools in the workpiece and the Z-axis (spindle nose) may produce sparks due to friction, and thereby lead to a fire of chips.

Do not use the machine with sparks splashing. Otherwise fire may happen. Procedures and various types of settings should be fully confirmed in advance to make sure the movements, eliminating the interference between the fixtures in order to avoid imposing heavy loads to the tools.

Chinps should be cleaned. If the internal chips stack inside the machine, the potential fire danger will increase. Cleaning should be


X

conducted on a regular basis, so as not to remove chip stacking.

Oil mist and dust are not allowed around the machine. Otherwise, fire will be caused due to sparks.

Warning

While processing a plammable workpiece, machine state should always monitored in case of fire for appropriate and timely measures.

A fire extinguisher is ncessary nearby for a sudden event of fire. Moreover, it is recommended that an automatic fire extinguisher be installed on the machine.

The material that is suitible for the automative fire extinguisher is as follows. Materials other than the followings may not be sensitive to the automative fire extinguisher. Resin; Foam resin; Sawdust; Cotton; Water-soluble cutting liquid; Non-water-soluble flammable liquids (gasoline, lamp oil, cutting oil,

machine oil, and lubricants. Almost all the non-water-soluble hazardous material).

Clean regularly the piping and wiring (especially the sensor and nozzle) within the automatic fire extinguisher. Of particular note is that the chips and cuting liquid attached to the sensor and nozzle will affect the sensing of the occurrence of fire and the spraying of liquid.

The use of the machine should be instantly stopped in the event the power cable and the connection cable are damaged. Otherwise, electric shocks or fire may happen. Before the replacement of the damaged cable by the maintenance staff, the machine may not be used.

There must be enough space around the cable clip. If the ceiling, walls, beams, and other items (such as customer-owned roof that is different from the genuine FANUC product, etc.) of the building where the machine is set in are too close to the cable, the possibility of fire and electric shock may increase when the power cord in the cable clip is broken.

Adequate coolant should always be guaranteed. Inadequate coolant may cause rise of temperature that leads to fire or damage to the tools and workpieces.

The roof is recommended. The roof is for the following purpose: in case of fire, the roof is able to prevent the fire from spreading to the ceiling of the building and reduce the spread speed; the roof also reduce the amount of oxygen within the cutting lquid baffle plate to accelerate the extinguishing of fire to promote the effectiveness of the automatic fire extinguisher.

h) Maintenance

Warning

Inspection and maintenance should be carried out regularly. The inspection items described in the maintenance sections of the manual must be implemented. Otherwise, the machine will cause death or injuries, or damage due to the failure.

Maintenance of the replacement parts should be in accordance with the implementation of the elements contained in the manual. Improper use of parts or wrong replacement methods will lead to machine failure or injuries.


XI

i) Machine Configuration and Operation Warning

The machine should be placed in a leveled environment. If the machine is placed in an unstable environment, the machine may move to bring unexpected injuries. The floor must in accordance with the following conditions while setting the machine. Even for heavy objects of 2.5t, the ground will not be deformed and

there will not be any problem; The floor should be leveled without any uplift or depression; The floor should be very hard, and even if imposed with 1.5 Mpa

(15kgf/cm²), the floor will not deform; The floor should be flat; The floor should not deteriorate with the passage of time; The floor should not deteriorate with changes in the environment due

to day-to-day use. Confirm that the Z axis (spindle nose) won’t descend before opening

the protective door. In some extreme cases, the Z axis may descend due to failure of the Z axis brake. It is necessary to notice if the Z axis descend after opening the protective door. The operation below the Z axis requires a wood block that is placed between the working table and the Z axis in case of failures to support the Z axis from descending.

Confirm if the spindle has stopped before opening the protective door while the power is off. When disconnecting the power in the rotation of the axis, due to the inability to control and stop the spindle, which will continue to rotate because of inertia, the chips may fly out, or injuries may happen if touching the spindle.

Pay attention to the descending of the Z axis (spindle nose) when disassembling the Z axis motor. When the motor is being disassembled, the Z axis may descend because the brake integrated in the motor is also removed. This may lead to injuries by being caught. For the removal of the motor, binds can be employed to fix the working table and the Z axis.

For the first time using the embedded Ethernet function, please contact your network administrator for advice, and pay attention to the IP address settings and make full communication tests. If the IP address is incorrect, failures may happen in the communication of the network that lead to wrong operation in other machines, so full attention should be paid.

Cranes, slings, or steel cables for hoisting the machine should be of the capacity over the weight of main machine part. Keep the machine in balance when hoisting.

Important

When using the roof as the cover over the whole machine, a vapor collector must be used. This is because the vapor of the coolant may diffuse and thus brings failure of the machine. In addition, when the high temperature exhaust of the spindle motor diffuses within the machine, failures may take place.

1.2 Programming

1.2.1 Overview

a. Program name

Every program has a program name. The program name an be specified

according to the following rules in programming:

* The initial two characters must be letters (full numbers or the name

in which the initial characters are numbers are not allowed, which may

cause system memory re-allocation that is not reversible for users and

may cause serious consequences.)

* Only letters, numbers, or underlines are allowed

* No separators are allowed (See the chapter of “Character Sets”)

* The point is only for an extention

* Maximum number of characters is 25

For example: FRAME52

b. Program Structure

An NC program comprises segments (as shown in the figure below).

In each segment a machining procedure is performed.

A segment comprises several words.

In the process the final segment contains an ending character: M2.

Segment Word Word Word … ;Note

Segment N10 G0 X20 … ;First segment

Segment N20 G2 Z37 … ;Second segment

Segment N30 G91 … … ; ...

Segment N40 … … …

Segment N50 M2 ;End of program

c. Word Structure and Address

The word is an element in a segment, which is used for displaying control

instructions. A word is composed of the following parts:

* Address character: the address character is a letter on most occasions.

* Immediate: A string of numbers, which may take on signs or a decimal.

Normally the plus sign is omitted.

Recompile


- 15 -

A word may contain several letters. The immediate and the letter are

separated by “=” sign.

For example: CR = 5.23

Moreover, G functions can also be called by a name of sign

For example: SCALE; enable scale

For the following addresses

R calculating parameters

H H function

I, J, and K interpolation parameter/central point

Extension address from 1 to 4 may used to get a larger address value. In

such case, their values can be assigned by “=”

For example: R10=6.234 H5=12.1 I1=32.67

d. Segment Structure

A segment contains all the data needed in performing a process.

A segment is normally composed of several letters and always ended with

the ending character “LF” (new line). A new line or pressing enter can

produce an end of paragraph character during coding.

When multi instructions exist in a segment, the following sequence is

recommended: N... G... X... Y... Z... F... S... T... D... M... H..., for which a

stepping of 5 or 10 is preferred. This is to provide convenience for inserting

snippets without modifying the line number.

To skip the segments that are not necessarily executed in each run, add a

slash “/” before the number of the segment. The skipping is enabled via the

machine control panel or the PLC interface control signal. Successive

segments can be skipped by adding slash “/” to all segment numbers. If the

skipping is enabled, all segments with “/” will not be executed while being

run. Also, the instructions in the segments in question are not taken into

account. The program will be executed prom the segment without a slash.

Comments are added via a comment character into a segment. A comment

starts with the character “;”, and ends with the end of segemnt.

Comments and the rest of the segment are displayed together in the current

segment.

Information is integrated along with a separate segment. Information is

displayed in a special area and kept valid unless overwritten by new

information or the program ends. In the information field a maximum of 65

characters can be displayed. Empty information will erase the previous

information.

1.2.2 Spindle Function (S Function)

Method to specify spindle velocity via the code

Input a code signal or read pulse signal by specifying a value following

address S, and in this way, the spindle velocity on one side of the machine

can be controlled.

Only one S code can be specified in a segment. If the movement command

and S code command exist in one segment, such as the actual usage

including bits of the S code or implementation order.

1.2.3 Auxiliary Function (M Function)

Overview

ON/OFF operations can be fulfilled via auxiliary functions M, such as

“enable/disable coolant” etc.

M… ;A maximum of 5 M functions are allowed in one segment

The implementation of the M function in the segments of axis movement is

as follows:

If M0, M1, and M2 functions exist in a segment containing axis movement,

they are available only after the movement of the axis.

For M3, M4, M5 fuctions, signals are transmitted into the internal PLC

before the movement of the axis. Axis movements only come into effect

after the controlled spindle is started with M3 or M4. There is no wait for

the stop of the spindle while executing M5 instruction. The axis has already

been sent into motion before the spindle stops (standard setting).

Other M functional signals and axis run signals are transmitted together to

the PLC. If intended M function is to be added before or after the

movement of the axis, an independent M function segment must be

inserted.

Please note that: the segment will interrupt the G64 continuous path method

and generate an exact halt status!

Example program

N10 S...


- 18 -

N20 X... M3 ;M function in a segment with axis

movement

The spindle starts prior to the X axis

N180 M78 M67 M10 M12 M37 ; A maximum of 5 M functions are

allowed

Besides M and H functions, T, D, and S functions are also available to be

transmitted to the PLC. A maximum of 10 instructions are available in a

segment.

1.2.4 Tool Function (T Function)

Tool changing can be fulfilled via T programming. Here tool changing as

well as preselection are all defined in the machine data:

* Change tools by T words (invoking tool) or

* Use T instruction carrying out a tool preselection, associated by M6

instruction to complete a tool change.

Attention:

An activated tool keeps available from end of program or power on/off.

In manual tool changing, the name of the tool must be entered into the

control system and it is to be made sure that the tool has been correctly

identified. For instance, a segment with new T tool code can be executed in

MDA movement mode.

T... ;Tool code: 1…32000, T0－Null

Example program

Tool changing without M6:

N10 T1 ;Tool 1

N70 T588 ;Tool 588

Tool changing with M6:

N10 T14 ... ;tool preselection 14

N15 M6 ;Tool change executed; T14 available

1.2.5 Spindle Positioning (SPOS Function)

Prerequisites: spindle must be designed to handle position control.

Through SPOS the spindle can be positioned at a definite angle. And the

spindle keeps at the position via position control.

Positioning speed is specified in the machine data.

When positioning via the axis rotation status (clockwise/counterclockwise)

the positioning direction remains unchanged. When positioning from an

idle state, the operation is carried out with the shortest offset. The direction

is from the starting piont to the end.

One exception: the initial run of the spindle, that is, the mesurement system

is not synchronized.


- 19 -

Under such situation the direction of the positioning is specified in the

machine data.

Instructions such as SPOS = ACP(…), SPOS = CAN(…), … for the spindle

are also applicable to the rotary axis(4th axis).

The positioning of the spindle can be synchronized with the movement axes

in one segemt. The segment ends with the end of the two movements.

SPOS=... ;Absolute position: 0…360 degrees

SPOS=ACP(...) ;Absolute size description, at the plus

approximate position

SPOS=ACP(...) ;Absolute size description, at the plus

approximate position

SPOS=IC(...) ; Increment size description, with the sign

Drilling is carried out at programmed spindle speed and feed until the final

CYCLE84 is available for tapping without a reciprocating fixture. For the

tapping with a reciprocating fixture, another loop CYCLE840 is applicable.

Only if the boring spindle is technically available for position control can

CYCLE84 be used.

Work flow:

Position reached before the loop starts:

The drilling position is located within the two feed axes.

The loop leads to the following movement sequence:

* Use G0 o return to the reference plane before the safety clearance.

* Positioning spindle stops (the value is in parameter POSS) and the spindle

is in feed spindle mode.

* Tapping to the final tapping depth at the speed of SST.

* Deep thread stay time (DTB parameter).

* Return to the reference plane before the safety clearance at as speed of

SST in reversed direction.

* Use G0 to return to the return plane; the spindle mode is changed through

re-programming before the call of the loop and the rotation direction

programmed under SDAC.

DTB:

DTB is programed as per second. When dealing with threaded drilling, it is

recommended DTB be omitted.

SDAC:

Rotation direction after the loop ends is programmed under SDAC.

Reverse of tapping is automatically executed in th loop.

MPIT and PIT (Pitch as thread size and value):

Tapping


- 21 -

Thread pitch value can be defined as thread size (rated thread is between

M3 and M48) or a value (the pitch between threads). Unwanted parameters

will be omitted or taken as a default value 0. Right hand or left hand thread

is defined by the sign of the pitch parameter:

* Plus→Right hand thread (M3)

* Minus→Left hand thread (M4)

If the two pitch parameter values are in conflict, alarm 61001 “Thread pitch

error” will be generated in the loop, which will thus be interrupted.

POSS (Spindle position):

Use the SPOS cammand to stop the spindle at the position defined in the

loop and switch to position control before tapping.

POSS sets the stop position of the spindle.

SST (Speed):

The parameter SST contains the spindle speed for the tapping progrom

G331.

SST1 (Return speed):

Return speed from the tapping position is programmed in SST1.

If the value of the parameter is zero, the return speed is in accordance with

that programmed in SST.

The direction of rotation in tapping in the loop is always automatically

reversable.

Example program: rigid tapping.

Rigid tapping without reciprocating fixture is to be carried out at the

position of X30 Y35 in the XY plane; the tapping axis is Z axis.

Unprogrammed delay time; the depth in programming is a relative value.

Rotation direction parameter and pitch parameter must be assigned a value.

digits after T, and T codes and M codes should be applied in 2 rows.

Machining codes can be inserted between T codes and M codes, and

tool predetermination can be achieved. The command is applicable to

chain magazine.

This instruction enables the machine to select tools with shortcut.

Notes:

1） When a tool number out of the specified number has

been specified, alarm (T code for changing tools illegal) will

occur.

2） If the specified tool number is the same as the tool number

mounted on the spindle, it is only available to carry out the

operation for orienting spindle, and Z-axis will return to the

origin, no operation for changing tools.

5.3 Tool Change of Turret Magazine

5.3.1 Operation steps for automatic and manual tool change 1) Automatic tool change

Execute TXXM6 in automatic modes (MDAI and AUTO); (values

range from 1 up to the maximum capacity of magazine)

2) Manual tool change

It is dangerous to change tools in manual modes, and operators are

not recommended to perform manual tool change, even though the

operators should be very familiar with the techniques of tool

change during the operation of manual tool change. The

introduction of manual tool change is only for tool change

operations when the operation cannot be executed in automatic

mode and it is necessary to take tools out of the machine with

manual operations. For the safty of the operators, the following

detailed operation procedures should be strictly followed:

a) Move Z-axis manually to a relatively safe location, i.e., where

the rotary tool disc cannot touch the blind rivets, and this location

is usually the second reference point of Z-axis of the machine tool.

But it is not absolutely so, it depends on the specific machine tool

configuration and specific tool magazine.

b) Press the magazine Forward or Reverse button on the PLC panel

of the machine tool in manual modes (JOG) and rotate the tool to

be taken off the magazine to the left window of machine tool


- 56 -

e) Move Z-axis below the magazine in manual mode, and perform

manual tool change within the normal effective travel of Z-axis.

5.3.2 Tool change actions of machine tool and magazine Tool change actions of magazine are as follows:

When operators execute tool change in automatic mode, machining

commands like tool compensation, coolant, rapid and

high-precision machining are cancelled, spindle is oriented, and

Z-axis is raised to the point of tool change. At this time, tools on

the spindle are safely moved back onto the magazine, and the

spindle continues to move in the positive direction of Z-axis until

the second reference point. According to the nearest tool selction,

the tool disc rotates and stops at the aimed tool. The spindle send

off air to blow the water and dust off the tool to prevent the spindle

from any damage when the tool is loaded. Z-axis moves downward

to take the tool out of magazine; NC automatically resumes most

modal commands of the programs edited by customer, and the tool

change action is completed.

5.4.2 Tool change actions of machine tool and magazine


- 58 -

Tool change actions of magazine are as follows:

When operators execute tool change in automatic mode, machining

commands like tool compensation, coolant, rapid and high

precision machining are cancelled, spindle is oriented, and Z-axis is

raised to the point of tool change (the second reference point). The

magazine move forward and the electromagnetic valve closes.

When the system detects the signal that the magazine moves

forward to the desired location, the spindle releases tools and the

tools are safely moved back onto the magazine. The spindle send

off air to blow the water and dust off the tool to prevent the spindle

from any damage when the tool is loaded. When the system detects

the signal that the tools have been released, the Z-axis moves in the

positive direction until the first reference point. According to the

nearest tool selction, the tool disc rotates and stops at the aimed

tool. Z-axis moves downward to the second reference point and

spindle chucks the tools. When the system detects the signal that

the tools have been chucked, the magazine moves backward and

the electromagnetic valve closes. Tools will be available to be take

out of the magazine to be chucked on the spindle. When the system

detects the signals that the magazine has moved backward to the

desired location and the tools have been chucked, NC

automatically resumes most modal commands of the programs

edited by customer, and the tool return and tool change actions are

completed.

5.5 Tool Change of Chain

5.5.1 Operation steps of automatic and manual tool change

1) Automatic tool change

Execute T XX in automatic modes (MDA and AUTO) (values range

from 1 up to the maximum capacity of magazine); For M06, the format

is as follows:

T_;

M6;

The tool number to be used should be specified by the two digits

after T, and T codes and M codes should be applied in 2 rows.

Machining codes can be inserted between T codes and M codes, and

tool predetermination can be achieved. The command is applicable to

chain magazine. This instruction enables the machine to select tools

with shortcut.


It is dangerous to change tools in manual modes, and operators are not

recommended to perform manual tool change, even though the operators

should be very familiar with the techniques of tool change during the

operation of manual tool change. The introduction of manual tool


- 59 -

change is only for tool change operations when the operation cannot be

executed in automatic mode and it is necessary to take tools out of the

machine with manual operations. For the safty of the operators, the

following detailed operation procedures should be strictly followed:

a) Move Z-axis manually to a relatively safe location. Usually, Z-axis

should be in a position higher than the level of chain and should not

collide with the positive limit of the machine tool. The purpose is to

avoid interference between magazine and spindle even for the

misoperation of rotating the chain and to prevent the damages on both

spindle and chain.

b) Connect the soft switch MAG.JOG and set parameter 14512[0] to 1;

c) Press the magazine Forward or Reverse button on the PLC panel of

the machine tool in manual mode (JOG) and rotate the tool to be taken

off the magazine to the opening of the magazine (the left window of

machine tool protection shield).

tool protection shield to take the tools down the magazine.

e) Close the door and disable the emergency alarm.

f) Ensure that the disc is moved backward to the desired location.

g) Move Z-axis below the magazine in manual mode, that is, within the

normal effective travel of Z-axis. The manual tool change is completed.

h) Break the soft switch MAG.JOG and set the parameter 14512[0] to 0.

5.5.2 Tool change actions of machine tool and magazine

Tool change actions of magazine are as follows:

When operators execute tool change in automatic mode,

machining commands like tool compensation, coolant,

rapid and high-precision machining are cancelled, and

spindle is oriented. When the chain’s 0 angle location

signal, brake signal, undercut signal, tool case level signal,

spindle tool chuck signal counter signal are detected to be

normal, the system will execute tool change actions.

Otherwise, alarms will remind the operator that the tool

change conditions are not met and tool change actions

cannot be performed. First, according to the principle that

the nearest tool will be selected, the magazine rotates to

the aimed tool, tool case is in vertical, and

electromagnetic valve closes. When the system detects

that the tool case has been lowered to the desired position,

Z-axis will be raised to the tool change point (the second

reference point) and the chain rotates to the undercut tool

position. When the system detects the signals that the


- 60 -

brake and undercut tool are on the desired locations, the

spindle will execute the tool release action and tools are

safely clamped on the chain. The spindle send off air to

blow the water and dust off the tool to prevent the spindle

from any damage when the tool is loaded. When the

system detects the signal that the tools are released to the

desired position, chain will rotate 180 degrees, tools on

spindle and tool case are change with each other, and the

spindle clamps the tools. When the system detects the

signal that the tools are clamped, chain will rotate to 0

degree, the tool case is upward and electromagnetic valve

closes. The tool case is upward and level, tools on the

spindle have been put back into the tool magazine, and

the tools taken out of the magazine are clamped on the

spindle. When the system detects the signal that the tool

case is upward to the desired position and the tools have

been clamped, the system automatically resumes most

modal commands of the programs edited by customer,

and the tool return and tool getting actions are completed.

5.6 Treatment of Tool Change Errors During changing tools, if the reset button is pressed, the tool change will

be stopped and alarm occurs. At this moment, it is able to execute

automatic recovering program to release all the relevant alarms.

1) Back-to-zero of tool magazine

When tool change is not correct and the tool clamped by spindle is not

the specified tool, the back-to-zero of tool magazine can solve the

problem. Back-to-zero means rotating the No. 1 tool seat in tool

magazine to the tool change position. The operation is to run the

following program block:

Execute M68 in MDA mode;

2) Manual rotation of tool magazine when magazine is not rotated to the

desired position or the chain is not at the origin

VMC Series Operation Details 6. Spinldle Functions

- 61 -

When magazine is not rotated to the desired position or the chain is not

at the origin, automatic tool change cannot be executed, and manual

6 Spindle Functions

6.1 Spindle speed S, rotating direction

Function When the machine is provided with the controlled spindle, the spindle

speed can be programmed under the address S, unit: round/min.

Rotating direction and the beginning and ending points of spindle

movement can be specified by M code instruction (see chapter 8.7:

auxiliary function M).

M3: the spindle runs clockwise.

M4: the spindle runs counterclockwise

M5: spindle stops

Note: the numbers after the decimal can be removed if the S value is a

interger, such as S270.

Note:

If noly M3 or M4 code instruction is included in the program block and the

movementg command of coordinate axis is written in, the M instruction

will be active before the corrdinate axis moves.

Default setting: the coordinate axis moves after the spindle moves (M3、M4)

and M5 is given before coordinate axis moves. But it is not necessary to

wait the spindle stopping. The coordinate axis moves before the spindle

stops.

Spindle speed zero (S0) is active when the program begins.

Note: the other settings can be performed by the machine data.

Programming example:

N10 G1 X70 Z20 F300 S270 M3 ;before X and Z axes move, the spindle

starts with the speed 270 round/min, clockwise direction.

...

N80 S450 ... ; speed changes

...

N170 G0 Z180 M5 ;Z axis moves and spindle stops.

6.2 Spindle speed limits: G25, G26

Function

The limits of speindle speed can be restricted by writing the

instruction G25 or G26 and the speed under address S. meanwhile, the data

in the former setting data will be replaced.


- 63 -

G25 or G26 instruction requires a single program segemnt.the speed

programed previously keeps the saved state.

Programming

G25 S... maximum spindle speed

G26 S... :minimum spindle speed

Note:

The maximum spindle speedcan be set in the machine data. the setting

parameters for the other limits can be activated by the operation panel.

Programming example

N10 G25 S12: maximum spindle speed:12 round/min

N20 G26 S700: maximum spindle speed:700 round/min

Hints:

The operating area can be restricted by the G25/G26 as well as the known

axis address.

6.3 Spindle positioning: SPOS

Functon

Preconditions: the spindle must be designed to be available for the

operation of position control.

The spindle can be oriented at an accurate rotating angle by the function

SPOS. The spindle can stay at the position by the position control function.

Positioning speed can bespecified in the machine data.

The positioning direction keeps the same from the positioning at spindle

rotating state (clockwise/counterclockwise). The positioning is operated at

minimum displacement when the positioning begins from the stationary

state. The direction is from the starting position to the end position.

The exceptional example: the initial running of spindle,i.e. the

measurement system is not synchronous. In the case, the positioning

direction is specified in the machine data.

The other operating instructions set by SPOS=ACP(…), SPOS=ACN(…),

etc. are also applicable for the rotary axis.

Spindle positioning operation can be performed with the movement of

coordinates in the same program block at the same time.The program block

can only be completed when the both operations are completed.

Programming

SPOS=... : absolute position: 0…<360 degree

SPOS=ACP(...): instruction of absolute dimension, toward the position in

positive direction.

SPOS=ACN(...): instruction of absolute dimension, toward the position in

positive direction.

SPOS=IC(...): incremental dimension instruction; the running direction is

specified by the symbol.

SPOS=DC(...): instruction of absolute dimension, return to the position

directly (with the minimum journal).


- 64 -

Programming example

N10 SPOS=14.3: axis position 14.3 degree.

N80 G0 X89 Z300 SPOS=25.6: spindle

positioning and coordinate movement are

performed at the same time. The program

block ens when all the operations are

completed.

N81 X200 Z300: N81block can be perated after the axis position in N80 is

reached.

6.4 Drive level

Function

At most five drive levels can be provided for the spindle to adjust the

speed/torque. The drive levels can be selected by the M code instruction in

program:

S M40: automatic stage change of drive levels

S M41 to M45: drive level 1 to 5

7 Auxiliary Functions of Machine

7.1 Hydraulic Station

Hydraulic station can be used in various applications as optional functions, especially in the clamping and releasing of tool by spindle, the shifting of spindle gear box, the releasing and clamping of digital rotating table and hydraulic clamps as we as the pressure measurement of pipes. The followings are the introductions for the above. Though a separately designed hydraulic station is usually equipped on a machine depending on the different optional functions of the machine for the different applications, the controlling principles of the separately designed hydraulic stations are the same. The start-up of hydraulic station:

a) When hydraulic station is used for clamping tool, mechanical gear box changing gear, NC table clamping it will be started automatically.

b) When hydraulic station is used for clamp work-piece, it will be started by the press of [HYON] key on the operator panel.

The hydraulic station can automatically start up when the power is on. When the pressure is measured to be in the working range, the hydraulic motor will stop rotating automatically and hold the current pressure; when the working pressure is exceeded, the hydraulic station will unload automatically to assure the reliable and stable running of hydraulic motor; when the pressure is under the working pressure, the hydraulic motor will start up automatically to assure the working pressure. The releasing and clamping of the shifting of spindle gearbox, tool and rotating table are the different actions which can be achieved by the controlling the relative electromagnetic valves on the hydraulic station. Because many measuring signals are on the hydraulic station to guarantee the reliable and stable work of the hydraulic, there are plenty of alarm information correspondingly. Of course, it depends on the concrete hydraulic station. If the customer found that the hydraulic station used by him is without the function, it is no doubt for meeting the customer’s requirement with the optimization price. The relative alarm information is as followed:

7.8.2 Illumination for Work-pieces Because the light in the protecting room is not enough, so it is necessary to install the illuminating devices for the operator to operate tools. The illumination of machine has a very simple operating mode with just pressing the “LIGHT” button on the operation button to switch the light. When the machine is power on, the light is automatically on.

7.9 Introduction of Machine Fixtures The choice of the machine fixture usually accords to the concrete

work-piece to be machined. The air operated fixture and hydraulic fixture with the same working principle are usually used in the daily work.

7.10 Transformers SIEMENS 3～380V control voltage is used in the series of machines.

When the main power supply is not of the 3～380V voltage, the servo transformer should be installed to transform the voltage to the required 3～380V for the machine. For the different configurations, the capacities of the different servo transformers are different, so it necessary to refer to the list of the purchased parts according to the concrete configuration.

7.11 Lubrication

There is lubrication pump on the machine supplying lubrication oil for linear guideways. And there are two methods to start the lubrication pump.

a) Automatic Lubricate In automatic lubricate mode, the lubrication pump start one time for some time and then stop some time automatically. The Stop Time = [C10] *5 minutes For example: If the PMC parameter Counter 10 is set 3, the stop time will be 15 minutes.The Run Time: T11 (ms), concrete operation is in the appendix H.3

b) Manual Lubricate Press the key [LUBRICATE] on the operator panel to start the lubrication pump. The run time of the pump is T9 (ms). There is another method to start lubrication pump. That is press the button on the pump.

- 78 -

12 Tool and Tool Compensation

12.1 General

Function

While programming the manufacture of the workpiece, neglect the length

and the cutting radius of the tool. You can program the size of the

workpiece on basis of the blueprint.

The parameters of tools should be input into a separate data zone.

In the program, you only need to call the tool code and its compensation

parameter and start the radius compensation if necessary. The controller

implements the locus compensation to manufactures the workpieces.

Utilize tools of different radius to manufacture workpieces.

Return to the place of the workpiece Z0—different length compensations:

12.2 Tool T

Function

Change tools by programming T code. Define both changing tools and

preselection in the data.

* Input T code to change the tool (tool calls) directly or

* Input only the command T to select the tool. Besides, input the command

M6 to change the tool.

T1-Tool 1 T2-Tool 2

T1- Tool 1

Workpiece contour

T2- Tool 2

T0-No tool

F-Tool hold reference point


- 79 -

Notes:

When a tool is activated, it will be always valid whether the program and

the power are on or off.

When changing a tool manually, the data of the tool should be input to the

control system and ensure it is identified. For example, a new program

segment with T code can be started under the operating mode MDA.

Programming

T... ; Tool code:1…32000，T0－No tool

Tips

The maximum number of tools that can be stored in the control system at

the same time: 128

Examples for programming

Don't input M6 to change the tool:

N10 T1 ; tool 1

...

N70 T588 ; tool 588

; input M6 to change the tool:

N10 T14 ... ; preselect the tool 14

...

N15 M6 ; implement the command of changing the tool；then T14 is valid

12.3 Tool Compensation Code D

Function

A tool can match different data groups from 0 to 9 (for several cutting

blades). Utilize D and the sequence numbers to program a separate cutting

edge.

If D is not programmed, D1 becomes valid automatically.

If D0 is programmed, the tool compensation value is invalid.

Tips

The maximum number of tools that can be stored in the control system at

the same time: 128(D code)

Programming

D... ; tool compensation code:1…9、

D0:no compensation number is valid！

Example for the matching of tool compensation codes:

Instructions

When calling the tool, tool length compensation is valid immediately; if D

code isn’t programmed, the value of D1 is valid automatically.

Each tool has its modified program segment—at most 9.


- 80 -

The first programmed, the first implemented and so does its axis. Please

pay attention to the valid G17 and G19 at present!

The tool radius compensation should be activated by G41/G42.

Examples for programming

Don’t use M6 to change the tool (use T only):

N5 G17; ensure the axis that is to be compensated

N10 T1; D1 of Tool 1 is valid

N11 G0 Z...; on the plane G17, Z is the compensation of the tool length that

is covered

N50 T4 D2 ; change into Tool 4，D2 of T4 is valid

...

N70 G0 Z... D1; D1 of T4 is valid and change into cutting blade

Use M6 to change the tool:

N5 G17; ensure the axis that is to be compensated

N10 T1 ; preselect the tool

...

N15 M6 ;change the tool，D1 of T1 is valid

N16 G0 Z...; on the plane G17, Z is the compensation of the tool length...

N20 G0 Z... D2 ; D2 of T1 is valid，D1－>D2 the gap of tool length

compensation is covered here

N50 T4 ; preselect T4，Notes: D2 of T1 is still valid！

...

N55 D3 M6; change the tool, D3 of T4 becomes valid...

Compensation Storage

In the compensation storage:

* Geometric size:length, radius

The geometric size includes many components: basic size and grain size.

The controller deals with these components, calculates them and gets the

result (for example: total length and total radius). These final sizes are valid

when the compensation storage is activated.

These values can be calculated by means of the command of the tool type

and G17，G18 and G19 (See the following diagram).

* Tool types

The geometric parameters and calculation methods are dependant on the

tool types (drill bits or milling cutters).

Special case of the cutting tool

For milling cutters and drill bits, parameters of length 2 and length 3 are

used only in special cases (such as length compensation of different sizes

for elbows).

Validity of 3D tool length compensation (special case):

12.4 Choice of Tool Radius Compensation: G41、G42

Function

The tool works on the plane G17 to G19 to compensate the radius.

The tool with a D code is valid. The compensation of the drill bit is valid by

G41/G42. The controller calculates the equidistant locus that the present

tool runs. The length of the locus is equal to the programmed outline.

Programming

G41 X... Y... ; the compensation is valid on the left of the workpiece

G42 X... Y... ; the compensation is valid on the right of the workpiece

Instruction: G41/G42 can be selected only in the linear interpolation(G0、

G1).

Edit two axes (for example on G17: X, Y) in the program. If only one axis

is given, the second axis will be evaluated based on the last programmed

size.

Left/right compensation:

Compensation Start

The tool returns along a straight line and is made plumb with the path at the

start.

Choose the start point correctly and ensure no collision.

For example: G42, start the compensation of tool radius:

Instructions

Normally, the program segment G41/G42 is followed by the first program

segment of the outline of the workpiece. But 5 segments (such as the

program segment that is commanded by M or feed action) that are not

defined displacement can stop the outline description.

12.5 Corner Features:G450, G451

Function

When G41/G42 is valid, utilize G450 and G451 to regulate the corner

features of the discontinuous corners from a section of outline to another.

The controller automatically recognizes the internal and external angles.

The internal angle must return to the point of intersection of the locus and

the Equidistant Line.

Programming

G450 ; linear transition

G451 ; point of intersection

Linear transition G450

The central locus of the tool is an arc. Its start point is the end of the

ex-curve and its end is the start point of the post-curve. Its radius is equal to

the radius of the tool.

Linear transition is valid when starting the next program segment with

operation commands.

of intersection of the equidistant lines (arc or straight line). If there is a

acute angle on the outline, there will be blank paths which are related to the

radius of the tool.

The control system changes to linear transition when reaching 100°.

Change to the transitional arc:

12.6 Cancel the Compensation of Tool Radius: G40

Function

Utilize G40 to cancel compensation (G41/G42). It’s also the start condition

in the program.

End the program segments before G40 through a normal mode (in the end,

the compensation vector is vertical to the tangent at the end of the locus); it

is independent of the start angle.

When G40 is valid, the tool bit is the benchmark. The tool bit will reach the

end when the option is canceled.

Make sure no collision when selecting the end of the program segment of

G40.

Programming

G40 X... Y... ; cancel the compensation of tool radius

Instructions: The compensation should be canceled only under the linear

interpolation (G0、G1).

Program two axes (for example on G17: X, Y). If only one axis is given,

the second axis will be evaluated based on the last programmed size.

End the compensation of tool radius:

N110 G40 G1 X... Y.. ; cancel the compensation of tool radius，P2

12.7 Special Case in Tool Radius Compensation

Repeat the compensation

Repeat the same compensation (such as G41-->G41) and there is no need to

write the command G40 during the new programming.

End the program segment before a new compensation at the end of its locus

according to its normal mode of compensation vector. Then start a new

compensation (the same as "change the compensation direction”).

Change the compensation code D

Change the compensation code D during the process. A new tool radius is

valid at the beginning of the new program segment. But it will change

thoroughly at the end of the segment. The changing values are implemented

continuously by the whole program segment and it is the same with the

linear interpolation.

Change the compensation direction

The compensation direction command G41 and G42 are able to change into

each other, and there’s no need to write the command G40.

End the program segment of the original compensation direction at the end

of its locus according to its normal mode of compensation vector. Then

start a new compensation direction (at the start point and at the normal

place).

Change the compensation direction:

Utilize M2 to break off the compensation

End the compensation by M2 (program ending) rather than by G40, the last

program segment with plane axes(from G17 to G 19) will end at the normal

place of the compensation vector. No compensation move. The program

ends.

Critical Manufacturing

Pay attention to the following situations when programming: in the

transition of the internal angle, the displacement of the outline is less than

For example: For example:


- 86 -

the tool’s radius. In two continuous internal angles, the displacement of the

outline is less than the tool’s diameter.

Avoid such case!

Check the program segments, avoid “necks” in the outline.

Please choose the biggest possible radius while examining and idling.

Acute angle of the outline

When the command G451 is valid, there are acute angles (the external

angle is less than or equal to 10°), the control system will automatically

change into the linear transition in order to avoid a long idled path.

Function

The cutting tool drill holes according to the speed and the feed rate of the

spindle in the program until it reaches the deepest depth. Drilling the deep

hole needs to drill at the maximum feed depth, increase the depth step by

step.

The drill bit returns to the reference plane after feeding every time. The

safety space is used to convey scraps or the drill bit draws back 1 mm to

convey scraps.

Procedures as followed are formed in the cycle:

Conveying scraps while drilling deep holes (VARI=1):

* G0 is used to return to the reference plane before the safety space.

* G1is used to move to the original drilling depth. The feed rate depends on

the parameter FRF (feed coefficient) in the program.

* How long it will stop in the last depth (parameter DTB).

* Use G0 to return to the reference plane before the safety space to convey

scraps.

*Stop time at the start position (parameter DTS).

* Use G0 to return to the late depth and reserve some space in advance.

* Use G1 drill to the next depth (the movement lasts until the deepest

depth).

* Use G0 to return to the returning plane.

Conveying scraps after drilling deep holes (VARI=1):

Instructions to parameters

Please refer to parameter CYCLE81 for parameters RTP、RFP、SDIS、DP、

DPR

Parameter DP(or DPR)、FDEP(or FDPR) and DAM

The depth of the central hole is based on the margin of the last and the first

drilling depth and it is calculated as follows:

* First, drill in the range of the drilling depth.

* From the second drill, the stroke is gotten from subtracting the first depth

form the last depth. It demands that the stroke is larger than the gradual

decrease.

* When the surplus is twice larger than the gradual decrease, the remaining

stroke is equal to the gradual decrease.

* The last two strokes is divided equally, so it is always larger than half of

the gradual decrease.

* If the first drilling depth doesn’t match the total depth, error 61107 will

appear “there is something wrong with the first drilling depth” rather than

implement the program.

Parameters FDPR and DPR have the same functions in the cycle. If the

values of reference plane and the returning plane are equal, the value of the

first drilling depth can be defined as the relative value.

In the program, the first drilling depth shouldn’t be deeper than the last one.

If so, the cycle will reduce the first drilling depth or drill only once to reach

the last depth.

DTB (stop time)

DTB programs the stop time (cut scraps) when the drill reaches the deepest

depth. Second is used as the unit.

of the cutting edge ($TC_MOP2[t,d]) is updated. In the process of

manufacturing, if the left life is monitored by “the warning limit of the tool

life” ($TC_MOP1[t,d]), information can be transferred to PLC by a

connection signal.

If the value of the left tool life is less than zero, it will alarm and set up

another connection signal at the same time. Then, the tool is “invalid” and

cannot be programmed until the “invalid” is canceled. So operators should

replace tools and ensure a valid tool.

Systematic parameter $A_MONIFACT

Utilization of systematic parameter $A_MONIFACT (data type is REAL)

is able to make the monitoring clock run slowly or fast. Set this parameter

before using the tool, such as considering the grain according to the

material of the workpiece.

Replace or end the program while the power is on, the parameter of

$A_MONIFACT is 1.0. the actual time is valid.

Example for systematic parameters:

$A_MONIFACT=1 The actual time of 1 minute is equal to the 1 minute

decrease of the tool life.

$A_MONIFACT=0.1 The actual time of 0.1 minute is equal to the 0.1

minute decrease of the tool life.


- 94 -

$A_MONIFACT=5 The actual time of 1 minute is equal to the 5 minute

decrease of the tool life.

Use RESETMON to update the set value

Set up the actual value as the set value.

-DEF must be used to define the parameter “state” of feedback information

at the beginning of the program.

DEF INT state can define different names to parameters (not “state”, at

least 15 characters, 2characters are in the beginning). The parameters exist

only in its program.

This is also applicant to mon. If it needs definition; it can be used as

numbers to transform (1 or 2).

15.3 Workpiece Number Monitoring

Monitor the number of the valid edges of the valid tools.

Workpiece number monitoring includes all monitorings of the edges. If the

counting number has changed because of the definition, the monitoring data

that is valid from last counting will be adjusted.

Update the number of the workpiece by operation or SETPIECE( )


- 95 -

Amend the number of the workpiece by HMI or SETPIECE() in the

program of NC.

Use the function SETPIECE, users can amend the monitoring data during

the manufacture process.

SETPIECE(n ) If SETPIECE(n) has been programmed, search the inner

storage of SETPIECE. If an edge is set up with the “storage”, the number of

the corresponding edges (the left number--$TC_MOP4) will reduce the set

value and cancel the corresponding “storage” (SETPIECE).

n : = 0... 32000 From last implement of the function SETPIECE

The workpiece number. The left number ($TC_MOP4[t，d]) will reduce this

value.

Instructions:

* SETPIECE( ) is invalid during the search of the program segment

* It is suggested that $TC_MOP4[t,d] be written only in simple program,

which needs programming a segment including STOPRE.

Update the set value

Update the set value, that is to count the surplus ($TC_MOP4[t,d]), Setup

VMC Series Operation Details 16. Drilling Pattern Cycle

- 97 -

16 Drilling Pattern Cycle The drilling pattern cycle introduces the geometric distribution of the drills

on the plane. A drilling process can be set up by calling a modal drilling

cycle before programming the drilling cycle.

16.1 Premise

Drilling Pattern Cycle without Application of Drilling Cycle

The drilling pattern cycle can also be used in other ways rather than be used

to the first drilling cycle, because the drilling pattern cycle is able to operate

beyond the installed parameters.

If a subprogram has not been applied before the drilling pattern cycle, error

62100 will appear “no drilling cycle active”.

Press the error response key to answer the error and then press

NC—START to continue. After that, the drilling pattern cycle goes back to

the place calculated by the input data, without calling the subprogram on

these points.

When the quantitative parameter is zero, the instruction should be the

number of the holes. When being called, the drilling cycle will warn and

stop operating with the error 61103 “the number of holes is zero”, if the

quantitative parameter is zero (or the parameter doesn’t exist).

Check the range of the input values.

In the drilling pattern cycle, there is no need to check whether the parameter

is reasonable; it is necessary to define the parameter.

16.2 Row Holes-HOLES1

Programming

HOLES1 (SPCA, SPCO, STA1, FDIS, DBH, NUM)

Parameters

SPCA Real

number

The first coordinate (X coordinate) of the plane

of the benchmark on the straight line.

SPCO Real

number

The second coordinate (Y coordinate) on the

plane of the benchmark (absolute value)

STA1 Real

number

The range of the included angel with the X

coordinate:--180 <STA1<=180

FDIS Real

number

Distance between the first hole and the

benchmark (input without “+” or “-”)

DBH Real Space between holes (input without “+” or “-”)


- 98 -

number

NUM Integer Hole number

Function

This cycle can be used to mill a row of holes which are distributed along a

straight line or in the grids. The type of the holes depends on the application

of the drilling cycle.

Process

According to the real place of the coordinates and the geometric

distribution and the cycle of the holes, the start position should be

calculated, from the first hole or the last one, aiming at avoiding the

unnecessary stroke.

Instructions on Parameters

SPCA & SPCO (the first and the second axes on the plane)

Define a certain position on the line as the benchmark in order to calculate

the space between holes. Define the distance from this point to the first hole

FDIS.

STA1 (angular magnitude)

Angle values should be input into STA1 with their degrees.

The straight line can be at any place on the plane. It is defined by the point

and line which are defined by SPC and SPCO and the angle formed with

the first coordinate axis on the plane.


- 99 -

FDIS & DBH (distance)

Use FDIS to program the distance between the first hole and reference

point defined by SPCA and SPCO. The parameter DBH defines the space

between any two holes.

NUM (number)

The parameter NUM defines the number of the holes.

Programming example: row holes

This process is used to drill those 5 thread holes that are parallel to ZX

plane and the space between holes is 20 mm. The start position of these row

holes are at the point of Z20 X30 and the first hole is 10mm from this

position. The geometric distribution of the row holes is introduced in the

HOLES1 cycle.

At first, use CYCLE82 to drill and then use CYCLE84 (tap without a

compensate clamp) to tap. The depth of the hole is 80mm (the distance

from the plane to the drilled hole)

- 102 -

Process

In the cycle, return to the position of the drilled circular hole on the plane

by means of G0 one by one.

Instructions to Parameters


- 103 -

CPA、CPO& RAD (the circle center and the radius)

The position of the circular hole on the plane depends on the circle center

and the radius. The value of radius must be a positive number.

STA1& INDA（the start angle and the increment angle）

According to these parameters, the distribution of the drilling hole on the

circle can be made.

The Parameter SAT1 defines the angle of rotation between the X coordinate

and the first hole. The parameter INDA defines the angle of rotation from

one hole to another.

If the parameter INDA is 0, the cycle is able to calculate the angular

magnitude according to the hole number, distributed evenly on the circle.

NUM（number）

The Parameter M defines the number of the holes.

Programming example: circular holes

This process uses CYCLE82 to manufacture 4 holes with 30 mm depth of

each hole. The last depth of the drilled hole is the relative value of the

reference plane.

The circle is made by the 42 mm radius and the center that is at the point of

X70 Y60 on the coordinate system. The start angle is 33 . The axis for

drilling has a safety space of 2 mm.
