Notes on using these functions in conjunction with tilting functions
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.
Program only the recommended transformations in the
respective reference system
Use tilting functions with spatial angles instead of with axis
angles
Use the Simulation mode to test the NC program
The type of tilting function has the following effects on the result:
If you tilt using spatial angles (PLANE functions except for PLANE
AXIAL or Cycle 19), previously programmed transformations will
change the position of the workpiece datum and the orientation
of the rotary axes:
Shifting with the TRANS DATUM function will change the
position of the workpiece datum.
Mirroring changes the orientation of the rotary axes. The
entire NC program, including the spatial angles, will be
mirrored.
If you tilt using axis angles (PLANE AXIAL or Cycle 19), a
previously programmed mirroring has no effect on the orientation
of the rotary axes. You can use these functions for direct
positioning of the machine axes.
