BobCAD-CAM Version 28 Training WorkbookCAD Basics


CAD BASICS

This section explains the CAD (computer aided drawing). It is important to become familiar with

the CAD commands to be able to move, modify and create geometry within the CAD system.Even if you are working with imported files generated elsewhere it is important to be able tomodify geometry within the BobCAD-CAM system.This Chapter will start by explaining individual commands then put them together usingpractical examples.

The Coordinate System

All coordinates in BobCAD-CAM use what is called the Cartesian coordinate system.The Cartesian coordinate system specifies each point uniquely in a plane by a pair of numerical

coordinates, which are the signed distances from the point to two fixed perpendicular directedlines, measured in the same unit of length. In CAD the axis used are X, Y and Z. Each referenceline is called a coordinate axis or just axis of the system, and the point where they meet is itsorigin. The origin in BobCAD-CAM is where the X, Y and Z axis meet on the screen; this point isknown as X, Y and Z 0 .When creating 2D drawings, all geometry or entities are positioned at Z0, this means thedrawing is 2D (Flat). All positioning and distances are measured in X and Y. See the image belowas an example.





It is important to understand the coordinate system being used, this is how entities are placedon the screen and measured.The coordinate system is also broken down into quadrants…. The axes of a two-dimensional Cartesian system divide the plane into four infinite regions,called quadrants , each bounded by two half-axes. These are numbered from 1st to 4th and

denoted by Roman numerals: I (where the signs of the two coordinates are I (+,+), II (−,+), III(−,−), and IV (+,−). When the axes are drawn, the numbering goes counter -clockwise startingfrom the upper right ("northeast") quadrant. See image below.





When placing entities in the workspace using the CAD commands they will be placed based onthe Cartesian coordinate system. In the image on the prior page you can see the point ( P) isplaced at 3, 5 in other words there is a point at X3 Y5. When entering coordinates into BobCAD-CAM the X and Y positions work in the same manner as depicted above.

NOTE: 2D rotations are generally rotated around the Z axis.

Angles entered into BobCAD-CAM are based on what is called Polar Coordinates.Polar coordinates are a two-dimensional coordinate system in which each point on a plane is

determined by a distance from a fixed point and an angle from a fixed direction.Circles can be created by picking a Cartesian center point- X, Y and Z location, along with degreevalues for the beginning and end of the arcs (Angles depicted below).





This is best shown in the example below, A half circle or arc drawn with the center coordinatesof X2.0 Y1.0 and Z0.0 (Cartesian coordinates) with a beginning angle of 0 degrees(PolarCoordinates ) and end angle of 180 degrees.

BobCAD-CAM Version 28 Training WorkbookSetting Up the Tool Database for Mill & Router


SETTINGUP THETOOL DATABASE FORMILL& ROUTER

NOTE: For adding Lathe tools, skip ahead to the lathe tutorial.

The Milling Tool Library contains all of the available system tools. This dialog box is used to add,delete, and modify tools. You can also load tool information from a previously saved file. On theleft side of the dialog box is a list of the supported Tool Types . The right side contains the ToolParameters list for each tool.

Taking the time to create all of the tools in your shop can greatly speed up the process ofcreating milling features. You can then add the tools to the Milling Tool Crib quickly to createthe equivalent of the tool changer for each job. The Milling Tool Crib tool list can be saved to a

file for repeated use.

When selecting tools from the Milling Tool Library for a milling feature, a specialized version ofthe tool list is displayed in the Select Tool dialog box.

NOTE: The only tools that must be entered into their library before use are the Tappingtools. This is made so that the machine feed rates can be properly calculated.





Adding a Tool Holders & Tools

To add a tool holder to the tool library, follow the instructions below.

To access the Milling Tool Holder Library , in the CAM tree, Right-Click CAM Default, and

Click Mill Tool Holders .

From here you can find Add Arbor and Add Holder, Holders and arbors are entered here and adrawing of them is generated dynamically as you build the Arbors and Holders.

NOTE: Arbors and Holders are only used for simulation purposes for 2 – 3.5 axis toolpaths atthis time it is not necessary to set up a holder nor an arbor, the default ones thatcome pre-installed with BobCAD-CAM can be used.Full documentation on all of the Arbor and Holder dialogues can be found within the

built in help system. To locate this information launch the help system by Clicking onHelp and then Click Help Topics . Search for the term “Arbor ” or “ Holder ”.





Adding a Tool to the Tool Library

To add a tool to the tool library, follow the instructions below.

To access the Milling Tool Library , in the CAM tree, Right-Click CAM Default, and ClickTool Library . In the left pane select a tool type, then Click on Add to add a new tool. Fill out theAdd tool dialogue box using the information that you have about your tools.

NOTE: The BobCAD-CAM Software’s tool library includes a limited amount of tool types thatBobCAD-CAM software supports.

Certain Unsupported or Custom tooling can be added to the library. If you add unsupportedtools to the tool library you must use an existing tool type for entry to the database, use the Tool

label (tools description) to identify these tools. Unsupported tools must be manually accounted for within your CAD drawings and machines offsets.





Using Tool Cribs

The Milling Tool Crib is comparable to the tool changer on a machine. It adds two advantages tothe milling system. First, the Milling Tool Crib can be loaded and saved before you create millingfeatures. When the milling feature operations are created, the system automatically selects the

appropriate tool from the Milling Tool Crib. Second, when selecting tools for milling operations,the tool crib shows all tools that are currently defined. By having the tools already defined, youcan eliminate the need to search the Milling Tool Library.

To add tools to a tool crib, follow the instructions below.To access the Milling Tool Crib , in the CAM tree, Under Milling Job, Right-Click

Milling Tools, and then Click Tool Crib . Use this method to view all the tools currently loadedin the Tool Crib.Click on Add Tool from Library , and select the tool to add then Click OK.

NOTE: In order to load tools into the Milling Tool Crib before creating milling features, youmust create the tools in the Milling Tool Library.

When tools are created in the Tool dialog box, of a milling wizard, that are not pre-loaded intothe Milling Tool Crib, the tools are then automatically added.When the Milling Tool Crib is accessed by Clicking Tool Crib from a milling wizard Tool dialogbox, the list automatically shows only the available tools for that operation type.



BobCAD-CAM Version 28 Training WorkbookMachine Setup & Post Processor Installation


MACHINESETUP& POST PROCESSORINSTALLATION

It is important to properly define your machines within BobCAD-CAM. The machine file controls

several aspects of the software.The machine file controls the following Items… Simulation Gouge & Collision Checking Multi-Axis Posting Settings Machines Physical Definition & Limits BobCAD-CAM Software Defaults Sub-Program Output

Post-Processor used Min. & Max. Feed Rates Min. & Max. Spindle Speed Unit Output Sequence Numbering. The file extension for G-Code files.

These Items must be configured for your software to work properly.The example used in the upcoming lesson is for a 3 axis mill with a 4 th axis rotary table. Thesteps used in the lesson will be the same steps used in creating any milling machine withinBobCAD-CAM.

BobCAD-CAM supports all G-Code based 3-5 Axis milling machines, the orientation andconfiguration of these machines are determined by the machine configuration within BobCAD-CAM.

It is strongly recommended that you first complete the tutorial in the next section before

attempting to setup your machine within BobCAD-CAM.





Installing Post Processors

A post processor is the translator that formats the G-Code output by BobCAD-CAM into thelanguage that your CNC machine can read. It is important that you locate and install a post

processor as soon as possible, without post-process BobCAD-CAM software cannot program theCNC machine.

Post-processors can be found & downloaded from the BobCAD-CAM website,http://www.bobcad.com . To install a post-processor, open your web browser and go to http://www.bobcad.com . Click onSupport and then Post –Processors. Follow the on-screen instructions to use the post-processor wizard to download your post processor, make sure to save the file. After the postprocessor has been saved to your computer, locate the file you had saved and Double-Click thefile to begin the installation.

The post installation copies the post file to the BobCAD-CAM software’s post directory, i tsdefault location which for V28 Mill is in C:\BobCAD-CAM Data\ BobCAD-CAM V28\Posts\Mill.

NOTE: After the installation is complete you will now be able to locate the file when youneed to access it when setting up a machine. After Installation is complete thereshould be no visible change, proceed to adding your machine.

Adding Your Machine(s)

Introduction

This tutorial covers how to create a machine. Machine creation starts with a machine definitionto define each element of the machine. Then the parameters are defined for each element ofthe machine, such as the moving direction and limits. The machine parameter values are usedin posting. For each element, geometry (.stl) files are added to define what appears in thesimulation window.

There are two levels of machine simulation: Standard Simulation and Pro Simulation. If youhave purchased the Machine Simulation Pro, 4 Axis Pro, 5 Axis Standard, or 5 Axis Pro module,then you have the Pro Simulation. Regardless of what level of machine simulation you have,you must still create a proper machine definition. The only difference is that with StandardSimulation, you can’t add geometry items to the machine definition that is used for simulation.

The following image shows the 4-axis machine that is created in this example.





The following image shows all of the individual geometry files (.stl), together in one Workspace.This is shown to help you understand how each geometry item is aligned in the Workspacewhen creating the geometry files for the machine. The second image, the view is madetransparent and zoomed in to show the coordinate system used to align the machine elements.





Part 1) Add a New Machine

Step 1. In the CAM Tree , Right-Click CAM Default folder, and Click Current Settings .

Step 2. On the left side of the Milling Settings dialog box, make sure that Machine

Parameters is selected.

Step 3. On the right side of the dialog box, in the Machine group, Click Add .







Step 8. In the Machine Parameters group, define the parameters for your machine.

Part 2) Locating the Machine Definition Files

Step 1. When you create a new machine, a folder is automatically created along with an.xml file of the machine definition, in the BobCAD-CAM Data folder. The defaultlocation is: C:\BobCAD-CAM Data\ BobCAD-CAM V28\MachSim\ Machine Name ....This is the same location in which the geometry files for the machine must bestored.

Step 2. For the purposes of this tutorial, the next step is to copy the geometry files from thedefault machine that is provided by BobCAD-CAM.

Step 3. Open the following folder: C:\BobCAD-CAM Data\ BobCAD-CAM V28\MachSim .Notice the folder named 4 Axis Example has been automatically created. If you openthe folder, you will see the 4 Axis Example.xml file that is created to save all of themachine information.

Step 4. Open the BC_4x_Mill folder, and select all of the files except the .xml file. PressCTRL+C to copy the selected files.

Step 5. Open the 4 Axis Example folder and press CTRL+V to paste the copied files into thefolder. These files are now available to add to the Machine Definition .





Part 3) The Machine Definition Dialog Box - Define the Y-Axis Parameters

Step 1. On the left side of the Milling Settings dialog box, Click Machine Definition .

Step 2. Notice the Machine group in the middle of the dialog box. The machine tree showsall of the machine elements that have been automatically created. This definitionincludes the linear axes, the rotational axis, and the dynamic holder and workpieceelements.

Step 3. The items in the tree are used to define or modify the parameters of eachcomponent. For example, in the tree, Click Y. Notice on the right, in the MachineData group, the parameters for the Y-axis are displayed.





Step 4. The Direction and the Limits for the Y-axis must be defined. By default the Y-axisDirection is defined by the vector X0Y1Z0. This defines the direction as the positiveY-axis. The machine being built requires the vector to be negative. Under Direction ,next to Y, Click in the box, and change the value to -1. The Y-axis vector isnow X0Y-1Z0.

NOTE: The vector direction for the axes is determined by the type of machine. For machinesthat the table (and not the head) moves in the X- and Y-axes, generally these valuesare negative. For machines where the head (tool) moves in the X- and Y-axes,generally these values are positive. The direction is determined by the relationship ofthe machine elements and which way they need to move to make the tool move in apositive direction in each of the X, Y, and Z axes.

Step 5. Under Limits , to the right of Min, Click in the box, and type the distance that thismachine element can move along the defined direction. For this example, type -10.This defines 10 inches of travel in the negative Y-axis direction.

Step 6. To the right of Max value, Click in the box and define the maximum distance that theelement can move along the defined direction. For this example, type 10. Thisdefines 10 inches of travel in the positive Y-axis direction.

Step 7. Set the Initial Value for this element to represent the elements starting position. Forthis example, type 0. This sets the initial position to the origin or zero location of theY-axis.





Part 4) Define the X-Axis Parameters

Step 1. In the Machine group, Click X to select the linear X-axis. In the Machine Data group,next to X, change the value to -1. Again, this defines that the X-axis elements must

move in the negative X-axis direction in order to cause the tool to move in thepositive direction in reference to the part.

Step 2. Under Limits , next to Min , Click in the box, and type -29. This value defines 29 inchesof travel in the negative X-axis direction.

Step 3. Next to Max , Click in the box, and type 11.

Step 4. Next to Initial Value , Click in the box, and type 0.





Part 5) Define the A-Axis Parameters

Step 1. In the Machine group, Click A to select the rotary A-axis. In the Machine Data group,notice that the Direction is defined as X1Y0Z0. This defines rotation around the X-axis.

Step 2. Notice that the Centerpoint is defined as X0Y0Z0. This defines the center point ofrotation in reference to the machine zero. Because the geometry was aligned to thezero of the reference point, this distance is zero.

Step 3. The next step is to define the rotary limits. Under Limits , next to Min , Click in thebox and type -100,000. You must set this value to the degrees of rotationsupported by the machine.

Step 4. Next to Max , Click in the box and type 100,000.

Step 5. Next to Initial Value , Click in the box and type 0.





Part 6) Define the Z-Axis Parameters

Step 1. In the Machine group, Click Z to select the linear X-axis. In the Machine Data group,notice that the Direction is defined as X0Y0Z1. This defines movement along the Z-axis.

Step 2. Under Limits , next to Min , Click in the box and type -9.

Step 3. The geometry item is added to the tree. In the Machine Data group, next to ID,select the name (geometry) and type Spindle .





Part 12) About the Dynamic Elements

The dynamic elements are the elements that can change with each program. The WorkpieceTransform contains the first set of dynamic elements in the tree. This transform includes thetoolpath, stock, fixture, and the workpiece. You do not have to define geometry for each of

these items because they are defined by each program that you create. This is also true for theHolder Transform elements. These dynamic elements are automatically created for you whenyou create a new machine.

Step 1. In the Machine group, under the Workpiece Transform , Click Initialstock . Notice theparameters in the Machine Data group. As with the other geometry items, you candefine a color for the element. It is helpful to define a different color for each elementthat appears in simulation.





Step 2. In the Machine Data group, next to Transparency, Click in the box and change the valueto 40 . This makes the initial stock item that is shown in simulation appear with forty-percent transparency. When this item is fully visible, it will still appear slightlytransparent which makes it easier to tell it apart from the stock or workpiece items.





Step 3. In the Machine group, under the Workpiece Transform , Click Stock .





Step 4. In the Machine Data group, notice the name in the Geometry row. For each programthat you create, when you simulate, the stock.stl (and the workpiece.stl ) files areautomatically created and placed in the machine's folder with the other geometry files(as shown earlier in this example). These files are created using the defined stock andthe selected geometry for the program.





Step 5. In the Machine group, under the Holder Transform , Click Tool . Notice the parameterdisplayed in the Machine Data group. You can change the color for each part of the tooland tool holder, as well as the transparency and reflectivity.





Part 13) About the Collision Check

At the bottom of the Machine tree, there should be an item labeled CC. This is the collisioncheck that is automatically added to the tree when you created the new machine. This itemdefines the dynamic elements that are included in the collision check.

Step 1. To add a collision check to the tree, Right-Click the top tree item 4 Axis Example , ClickAdd CollCheck , and Click Tool-Workpiece . This adds a collision check to the tree that isautomatically set between the workpiece and the tool.





Step 2. In the Machine group, Click the new collision check item ( CC1). Notice the informationin the Machine Data group. There are three boxes displayed. The larger box on the leftside contains all of the items that are available to add to a collision check group. Thetwo boxes on the right, Group 1 and Group 2 , define the items that are collisionchecked. Any items in Group 1 are collision checked with the items in Group 2 . The

Workpiece-Tool collision check that was added automatically places the Workpiece inGroup 1 and the Tool is placed in Group 2.

Step 3. To add an item to a collision check group, in the list on the left side, Click the item toadd. Next to the Group box to which the item is added, Click .

Step 4. To remove an item from a collision check, Click the item to remove, and then next tothe Group box, Click .

Step 5. If you add a User Defined collision check, no items are automatically added to the

Group 1 and Group 2 boxes.

Step 6. To finish the machine creation and save the information, at the bottom of the MillingSettings dialog box, Click OK.





Part 14) Additional Machine Parameters

After your machine has been created, you also need to define the Posting parameters for themachine.

BobCAD-CAM Version 28 Training WorkbookMachine Setup


MACHINESETUP

This dialog box is used to select the Machine Setup from the CAM Tree, define the machining

origin for the stock, as well as a few other machine settings.

Machine Setup

Machine Setup - this list shows all of the available Machine Setups in the CAMtree. Select the Machine Setup that you want to edit.

Origin

The machining origin defines the coordinate system used for all milling features contained inthe Machine Setup. When the Machine Setup dialog box is open, the stock is automaticallyoutlined with wireframe entities to aid you in selecting the machining origin to use for theMachine Setup. This eliminates the need to create geometry just to set the machining origin,although you can do so, if it is necessary. You must select one of three methods to set themachining origin.





Pick Origin Origin - enables selection mode for you to select geometry to define the machining

origin. X Direction - enables selection mode for you to select geometry to define the X-axis

direction.

Reverse Direction - reverses the current X-axis direction.

Y Direction - enables selection mode for you to select geometry to define the Y-axisdirection. Reverse Direction - reverses the current Y-axis direction.

Z Direction - enables selection mode for you to select geometry to define the Z-axisdirection. Reverse Direction - reverses the current Z-axis direction.

Enter Origin - allows you to type coordinate values for the machine origin. Select thisoption to type coordinate values in the X, Y, and Z boxes. (The Enter option must beselected in the Size group.)

Pick From Existing UCS - uses an existing UCS (user coordinate system) from the UCS tabof the Layer-UCS-Post Manager. Select this option to enable the UCS list.

UCS List - select from the available user coordinate systems to define themachining origin.

TIP: When using the Stock Wizard, the Enter boxes for geometry and origin selection display

the current size of the stock.

Reset to Stock Coordinate - sets the machining origin on the stock to the same locationas the stock coordinate system from the Stock Definition dialog box.







Selection Methods

When selecting geometric entities from the workspace for an origin or axis direction: For the Origin, you must select points or surface edges. Although, you can Click a line or

arc and the closest snap point of the entity is used. To view the snap points, while in

selection mode, press and hold down Shift and Click the entity. You can then Click thepoint to use.

For the X, Y, or Z Direction, you must select points, lines, or surface edges. You can alsouse snap points to create custom directions. When you use a snap point to define adirection, the direction uses the current origin location and aligns the selected axis tothe selected snap point.

When defining the machining origin in the Machine Setup page: Geometric entities are automatically created to assist you in selecting the machining

origin. The stock is outlined by lines and points, and a center line with points is also

drawn. When selecting geometry for the origin or a direction, you can Click theseentities.

The Machine Setup Dialog Box

This describes using the Machine Setup after completing the Stock Wizard. You first select aMachine Setup, and then define the machining origin of the part, as well as selecting a workoffset, and clearance plane. Full documentation on all of the Machine Setup dialogue can befound within the built in help system. To locate this information launch the help system byClicking on Help and then Click Help Topics . Search for the term “ Machine Setup ”.

Select the Machine Setup

The Machine Setup group at the top of the dialog box lists all the Machine Setup itemscurrently in the CAM Tree . Click the Machine Setup arrow and select the appropriate setupfrom the list to add toolpath under the correct work offset.





How to Select the Machining Origin

The Machine Setup dialog box is used to set the machining origin or work offset for the part onthe machine. When this dialog box is opened, the stock shows the bounding box made of linesand points. These lines and points are automatically created, for your convenience, to use when

setting the machining origin. By default, the machining origin is located at the WCS or worldcoordinate system (X0 Y0 Z0) as shown next.

The previous image has shading turned off to better show the bounding boxselection entities.

Step 1. If you want to use the top and center of the stock as the machining origin, ClickReset to Stock Coordinate . This uses the stock origin from the Stock Specificationtab .





Step 2. To change the machining origin to a different location, in the Origin group, Click inthe Pick Origin box, and select the desired location from geometry in the graphicsarea. Once you pick a point, the move is automatically executed without the need toClick OK.

TIP: The bounding entities that are created in the Machine Setup dialog box are for yourconvenience in setting the machining origin. You are not limited to using these entitieswhen setting the machining origin.

The machining origin is now set to the lower-left corner on the top of the stock.

The direction of each axis of the machining origin can be altered in the Origin group. Forexample, you can Click in the X-axis box, and then select the X-axis direction using geometry inthe graphics area. This can also be used to create custom orientations of the machining origincoordinate.





How to set the Machining Origin using the Enter Method

Step 1. In the Origin group, select Enter Origin , and type a values in the X, Y, and Z boxes todefine the origin location.

The values are from the WCS.

Step 2. The default directions of the Machining Origin follow that of the WCS.

Step 3. To change the direction of one the coordinate system axes, Click next to X, Y, or Z Direction to reverse the positive and negative direction of the corresponding axis.

How to set the Machining Origin using Pick From Existing UCS

Step 1. In the Origin group, select Pick From Existing UCS .

The UCS list becomes available.

Step 2. Click the UCS list arrow and select the desired UCS.

TOOLPATH TEMPLATESETUP

Toolpath Pattern Setup

To access the Tool Pattern Global dialog box, in the CAM Tree , Right-Click CAM Defaults ,and then Click Tool Pattern .

The following list provides definitions for important BobCAD-CAM terms that are used. A Feature is a container for machining operations and it is defined by the geometry selection (or

geometry feature) to which machining operations are applied. A Template is a predefined (default) set of operations that are applied to a feature. An Operation is a toolpath that is applied with a specific machining purpose, such as drill,

profile, or pocket.

There are two main parts of the Tool Pattern dialog box. On the left side of the dialog box is the Featureand Operation Template tree. The items under each feature type folder contains all of the availableoperation templates for that feature. When you select an operation template, the Operations inTemplate and Available Operations lists are displayed on the right side of the dialog box. This is thesecond part, the Operations lists. You use the operations lists to customize the Tool Pattern.

Operations in TemplateThe Operations in Template list shows the default operations that are used when you create afeature using the selected template.

TIP:

The number and order of operations can be customized in the CAM wizard (at any time duringor after feature creation).







Drill Operation Setup

The drilling operations within BobCAD-CAM are multi-tool or compound operations meaning,that if you choose to drill a hole the software by default will use first a center drill and then adrill or if you tap a hole, by default they software will Center Drill, Drill then tap the hole. These

features can be fully customized to include multiple tools or to only use single tools.To edit the Tools used within features follow the instructions below.

Drilling Parameters

Much of the drilling done by BobCAD-CAM is automated. BobCAD-CAM automatically accountsfor items such as drill tip angle and through holes and adds depth to the drilling operations.Before creating a program for drilling you should first understand exactly what BobCAD-CAM isgoing to do when drilling. The drilling parameters used by BobCAD-CAM can be customized tosuit your needs, see the information below to see how to access the drilling parameters and

how to change or edit them.The drilling parameters are configured within Cutting Condition Parameters see below forinstructions on how to access them.

BobCAD-CAM Version 28 Training WorkbookLathe Tutorial


LATHETUTORIAL

The Lathe Tutorial Video will guide you through creating a simple lathe part using an imported

file, below are steps to create stock, adding turning features, post G-Code, and simulate for anypart.

How to Add a Tool

Right-Click Turning Tools to open a shortcut menu with the following commands.

Turning Tools Tools - opens the Tool Library showing the available system tools. You can create

or modify tools from this location.

Tool Crib - opens the Tool Crib for you to load all of the tools that you need forthe job. Verify Tool Assignment - displays the Assigned Tools dialog box containing all of

the tools that are currently used in the program. The tool numbers used in thesoftware may not match the tools as they are listed on the machine, so this itemis provided so that you can reassign those numbers to reflect what is actuallyused in your shop.

To add a tool to the Tool Library

To add a tool to the tool library, follow the instructions below.

To access the Lathe Tool Library , in the CAM tree, Right-Click CAM Default, and Click ToolLibrary . In the left pane select a tool type, then Click on Add to add a new tool. Fill out the Addtool dialogue box using the information that you have about your tools.





How to Create Stock Using the Stock Dialog Box

When creating Turning Jobs, one of the first steps is stock creation. The Lathe Stock Wizardprovides an easy to use stock creation tool that handles basic cylindrical stock and custom(revolved) stock geometry. This is an important part of the job setup as the stock is used to

define the clearance values and toolpath creation for the job.

There are two pages in the Stock Wizard: Stock Type and Stock Definition. The Stock Type canbe cylindrical or revolved for custom stock creation. The Stock Definition handles the stocklocation and size. After creating the turning stock for the job, you can Click next to godirectly to the Machine Setup dialog box to define the clearance plane values for the job.

This is an important part of the job setup as the stock and machine are setup together and usedto define the Feature parameters, clearance values, and toolpath creation for the job.

To open the Stock Wizard, do one of the following : When creating a new job: in the Machining Job dialog box, select Turning , and Click

Stock Wizard .

After creating a new job: in the CAM tree, Under Turning Job , Right-Click TurningStock , and Click Stock Wizard.

The Lathe Stock Wizard displays in the Property Manager.





Stock Specification

Stock Type

Select one of the following options to set the type of stock created.

Cylindrical - creates a cylindrical stock with an outside diameter, an optional insidediameter, and a length.

Revolved - creates custom turning stock by revolving 2D geometry around the lathe Z-axis.

The following sections explain the parameters that display for each Stock Type.

Cylindrical

Size

The stock size is set using the followings parameters.

Stock Diameter - sets the outside diameter of the stock. Internal Diameter - sets the inside diameter of the stock. Length - sets the length of the stock along the lathe Z-axis.

Stock Origin

The stock origin is used to define the starting point/location of the stock along the Lathe Z-axis.This is the front face of the stock.

Enter Origin - enables the Z box to define the origin. Z - type the Z-axis value for the front face of the stock in reference to the Lathe

machining origin (which is fixed at the WCS).





Revolved

Size

The size of custom stock is defined by revolving custom wireframe geometry that you havealready created. After selecting the geometry to revolve, you can still modify the values in thedialog box to further modify the stock size.

Pick Geometry - enables selection mode for you to select a custom chain to revolve.After selecting the chain, Click OK ( ) to confirm the selection.

NOTE: The following values can be altered after selecting geometry. When you changethese values, the stock preview is not updated in the Workspace, but the values aresaved and automatically loaded in the Feature page of the wizard.

Stock Diameter - displays the outside diameter of the stock. Internal Diameter - displays the inside diameter of the stock. Length - displays the length of the stock along the lathe Z-axis.

After setting the stock size in the Stock Definition, Click (next) to go to the Machine Setup .

Machine Setup

The Machine Setup dialog box for Lathe only contains the clearance plane values for the job asexplained next.

Clearance

Face - sets the amount of clearance that is applied (in Z) for rapid movements along thestock face.

Diameter - sets the amount of clearance applied (in X) for rapid movements along theoutside diameter of the stock.

Internal Diameter - sets the amount of clearance applied (in X) for rapid movementsalong the inside diameter of the stock.

After setting the parameters, Click OK to close the dialog box and start creating Lathe Features.







Step 1. Add a Lathe feature based on the target geometry.

Step 2. In the first page of the wizard, you assign the feature geometry.

(After finishing the wizard, any changes to the feature geometry are made using the

CAM Tree. The geometry item in the wizard is not available when editing a feature.)

Step 3. In the second page of the wizard, you define the feature parameters.

The settings you define here are applied to all operations in the feature.

Step 4. In the third page of the wizard, the Machining Strategy, select a Template for thefeature.

Modify the Current Operations to contain the desired number and order ofoperations for the feature.

(When editing a feature, the Template of the Machining Strategy can't be changed.You can still add, remove, or reorder the Current Operations, it is only the templatethat can't be changed. This is done because the Template is used to set CuttingConditions.)

Step 5. In the remaining pages of the wizard, you define the operation-level parameters.This includes the tool data, parameters, rapids, and leads for each operation thatyou selected for the feature.

Step 6. After defining the feature parameters, compute the toolpath for the feature, andexamine the results.

If any changes need made, edit the feature, and compute to add the changes.





The Feature Shortcut Menus

The top level of the feature, which displays the feature name, is used to edit the feature, insertfeatures, and set the feature status using the following commands.

TIP: When you insert a feature, it is added below the current feature.

Feature Type

Edit - opens the Lathe Wizard dialog box for you to edit the feature. Compute All Toolpath - computes the operations of all features contained in the

Machine Setup.

Rs-232 Setup

Follow the steps below to set up the Rs-232 Communication between BobCAD-CAM and yourCNC machine.

Step 1. Gather all necessary data.In order to set up the communications you must first have the followinginformation.Baud Rate:Data Bits:Stop Bits:

Parity:Flow Control:The Computer's Comm Port Number:





Step 2. Ensure the serial cable correctly configured. The cable must be properly configured "wired" for your machine. Cables can bepurchased through BobCAD or through your machine dealer.

Step 3. Make sure your serial port is installed correctly configured .

The serial port should have its own baud, parity, data bits, and flow control. Thesesettings must be set to match your machine settings

To access the Device Manager, use the following method:For Windows Vista:

1. Left-Click Start2. Left-Click Control Panel3. Left-Click Performance and Maintenance4. Left-Click System5. Left-Click the Hardware Tab at the top of the new window6. Left-Click Device Manager

For Windows 7:

1. Left-Click Start2. Left-Click Control Panel3. Left-Click System and Security4. Left-Click System5. Left-Click Device Manager

For Windows 8:1. Right-Click the Start normally located on the bottom left of the computer screen2. Click Device Manager

Once in the Device Manger:

1. Go to the Ports tab2. Expand the ports tab3. The Comm Port Should be displayed below this tab.4. Right-Click on the Comm Port that is being sent through and then ClickProperties.5. In the new window Click Port Settings.

Step 4. Set your machine to Receive.-If you are not sure how to do this you will need to consult your machine manual ordealer.





Step 5. Launch the communication software (Predator Editor). To launch the editor use any of the following methods:

-In BobCAD-CAM Click on Modules then Edit CNC.

-In the Layers-UCS-Post Manager Right-Click in the Posting Tab then Left-Click Edit.

- From the Windows desktop Double-Click the PEditor Shortcut.

Step 6. Configure the communication software (Predator Editor).From the Editor Click on DNC then Properties set the Port, Baud, Parity, Data, Stopand Flow Control Values.Click Next 4 times then Click finish . (The settings on all but the first page need not bechanged. Only the Values described above.)

Step 7. Send a file to the Machine. From the editor Click on DNC then Send To CNC.

Trouble Shooting Notes:

1. A "standard" RS-232 null modem cable from an electronics store will not work. The cablemust be wired properly for the machine.2. The cable must be a serial cable. A parallel cable will not work.3. USB to serial adapters can be problematic. An internal serial card is always a better solution.4. If you do not know the proper settings for your machine, contact your machine manufactureras they will be able to provide the proper settings to you.5. If no port appears in the device manager, you will need to install or reinstall your serial portdevice.6. If using a USB to serial adapter (not recommended!), ensure the driver disk has been loadedand the settings (baud, parity, data bits and flow control) are the same as set on your machine.7. If the cable is improperly configured sometimes it is possible to send but not receive, andvice versa.8. If running in a DNC mode you may need to include a line delay amount. Set this value to 0 forstandard RS-232 communication.
