FUNCTION PARAXCOMP MOVE
Example
13 FUNCTION PARAXCOMP MOVE W
The PARAXCOMP MOVE function can be used only in
conjunction with straight-line blocks (L)
The control 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 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.
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the PROGRAM FUNCTIONS soft key
Select FUNCTION PARAX
Select FUNCTION PARAXCOMP
Select the FUNCTION PARAXCOMP MOVE
function
Define the parallel axis
Possible offset values (U_OFFS, V_OFFS and W_OFFS
from the preset table) to be taken into account will
be specified by your machine tool builder in the
presetToAlignAxis machine parameter (no. 300203).
Your machine tool builder can also activate the
PARAXCOMP functions permanently using a machine
parameter.
