10.2 Working with the Parallel Axes
U, V and W
Overview
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.
The TNC provides the following functions for machining with the
parallel axes U, V and W:
Your machine must be configured by the machine
manufacturer if you want to use parallel-axis functions.

Function Meaning Soft key Page
PARAXCOMP Define the TNC's
behavior when
positioning parallel axes Page 320
PARAXMODE Define the axes the TNC
is to use for machining Page 321
After the TNC is started up, the standard configuration is
always effective.
Parallel-axis functions are automatically reset by the
following functions:
„ Selection of a program
„ End of program
„ M2 or M30
„ Program cancellation (PARAXCOMP remains active)
„ PARAXCOMP OFF or PARAXMODE OFF
You must deactivate the parallel-axis functions before
switching the machine kinematics.
