FUNCTION PARAXCOMP DISPLAY

Use the

PARAXCOMP DISPLAY function to activate the display

function for parallel axis movements. The TNC considers the
traverse movements of the parallel axis in the position display of the
associated principal axis (sum display). Therefore, the position display
of the principal axis always displays the relative distance from the tool
to the workpiece, regardless of whether you move the principal axis
or the minor axis.

FUNCTION PARAXCOMP MOVE

The

PARAXCOMP MOVE function can be used only in

connection with straight-line blocks (

L).

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.
