Working plane coordinate system WPL-CS

Application

In the working plane coordinate system WPL-CS you define the position and orientation of the input coordinate system I-CS and therefore the reference for the coordinate system in the NC program. You do this by programming transformations after having tilted the working plane.

Description of function

Properties of the working plane coordinate system WPL-CS

The working plane coordinate system WPL-CS is a three-dimensional Cartesian coordinate system. You use transformations in the workpiece coordinate system W-CS to define the coordinate origin of the WPL-CS.

Workpiece coordinate system W-CS

If no transformations are defined in the W-CS, then the position and orientation of the W-CS and WPL-CS are identical.

Transformations in the working plane coordinate system WPL-CS

HEIDENHAIN recommends using the following transformations in the working plane coordinate system WPL-CS:

With these transformations you modify the position and orientation of the input coordinate system I-CS.

 
Notice
Danger of collision!
The control reacts differently to the various types of transformations as well as their programmed sequence. Unexpected movements or collisions can occur if the functions are not suitable.
  1. Program only the recommended transformations in the respective reference system
  2. Use tilting functions with spatial angles instead of with axis angles
  3. Use the Simulation mode to test the NC program

Notes

  • The programmed values in the NC program refer to the input coordinate system I-CS. If you do not program any transformations in the NC program, then the origin and position of the workpiece coordinate system W-CS, the working plane coordinate system WPL-CS, and the I-CS are identical.
  • Input coordinate system I-CS

  • During pure 3-axis machining, the workpiece coordinate system W-CS and the working plane coordinate system WPL-CS are identical. In this case, all transformations influence the input coordinate system I-CS.
  • The result of transformations built upon each other depends on the programming sequence.
  • As a PLANE function (#8 / #1-01-1), PLANE RELATIV is in effect in the workpiece coordinate system W-CS and orients the working plane coordinate system WPL-CS. The values of additive tilting always relate to the current WPL-CS.
