11.4 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.
