11.5 Working with the Parallel Axes U, V
and W
Overview
Your machine must be configured by the machine
manufacturer if you want to use parallel-axis
functions.
Depending on the configuration, the PARAXCOMP
function may be activated as standard.
Refer to your machine manual.
The axes U, V and W are secondary axes parallel to the principal
axes X, Y and Z, respectively. Principal axes and parallel axes are
permanently assigned to each other.
Principal axis Parallel axis Rotary axis
X U A
Y V B
Z W C
The TNC provides the following functions for machining with the
parallel axes U, V and W:

PARAXMODE
Define the axes the
TNC is to use for

After the TNC is started up, the standard
configuration is always effective.
You must deactivate the parallel-axis functions before
switching the machine kinematics.
