FUNCTION PARAXCOMP MOVE
The TNC uses the PARAXCOMP MOVE function to compensate for the
movement of a parallel axis by performing a compensation movement
in the associated principal axis.
For example, if a parallel axis moves in the negative W-axis direction,
the principal axis Z simultaneously moves 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 machine: Retract
the spindle sleeve to move the cross beam down simultaneously.
