FUNCTION PARAXCOMP MOVE

The PARAXCOMP MOVE function can be used only in
connection with straight-line blocks (L).
The control uses the PARAXCOMP MOVE function to compensate
for movements of a parallel axis by performing compensation
movements in the associated principal axis.
For example, if a parallel-axis movement is performed in the negative
W-axis direction, the principal axis Z is moved simultaneously in the
positive direction by the same value. The relative distance from the
tool to the workpiece remains the same. Application in gantry-type
milling machines: Retract the spindle sleeve to move the cross beam
down simultaneously.
