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 336
PARAXMODE Define the axes the TNC is
to use for machining Page 337
After the TNC is started up, the standard configuration is
always effective.
Parallel-axis functions are reset by the following functions:
„ Selection of a program
„ End of program
„ M2 or M30
„ Program cancelation (PARAXCOMP remains active)
„ PARAXCOMP OFF or PARAXMODE OFF
You must deactivate the parallel-axis functions before
switching the machine kinematics.
