JOINT FRAME C. S.

2

JOINT coordinate system is coordinate system of individual axis. Each axis rotates around its rotation center. JOINT c.s. is predetermined and cannot be changed.

What happens if J3 is moved in joint c.s.?

CARTESIAN C. S.

3

The robot position in Cartesian c.s. is described with position coordinates x,y, z and rotations w, p, r.

CARTESIAN C. S.

4

Right hand rule may be used for axis designation and axis rotation.

How moves the robot in C.c.s.?

WORLD C. S. AND TOOL C. S .

5

The world coordinate system is predetermined and cannot be changed. Based on WORLD c.s. USER AND JOG c.s. are defined. The c.c.s. origin is in the center of the second axis. Tool c.s. defines position of the tool center (TCP- tool center point) with respect to the flange center.

TOOL coordinate system

WORLD coordinate system

USER C. S . AND JOG C. S.

6

USER c.s. is set manually by the user. 9 coordinate systems is predetermined. In USER coordinate system the origin and rotation are set according to the world coordinate system. JOG c.s. is used for easier manual robot movement in manual regime.

If the TOOL or USER coordinate systems are changed, the toolpath has to be preprogrammed otherwise tool collision may occur.

TOOL FRAME- TOOL C.S.

7

TOOL frame is Cartesian coordinate system, which defines tool center point (TCP) and tool direction (which is normally z axis). The center point of the flange in 6th axis is default TCP.

TCP must be moved to the tool origin, which is specified by its geometry. The user defined TCP is a relative distance and orientation in respect to the default TCP.

TOOL coordinate system

User defined TOOL c.s.

Default TOOL c.s.

TOOL FRAME- TOOL C.S.

8

The tool frame c. s. may be determined by:

- Three point method

- Six point method

- Direct entry

- Two point + Z

TOOL FRAME- THREE POINTS METHOD

9

By using three points method the TCP is defined by selecting three points with different tool orientation.

The three point method defines just the movements in x, y, and z of the TCP. The rotations w, p and r stay the same as in the default TCP.

ROBOT MOVEMENT TYPES

15

J- Joint motion. Is a basic robot movement. The toolpath is nonlinear. Tool speed is determined with % of the maximum speed.

L- Linear motion. Is a controlled movement from first to second position. The TCP moves in a straight line.

TERMINATION POINT

16

FINE- robot moves and stops in a point and then continuous to a next point.

CNT- robot approaches to the point but never reaches it. The CNT value defines the approach distance.
