Before G37, program a linear contour element as a
reference
Machine the thread with G31
For standard threads, the parameters P, R, A and W
are defined by the control
Use Q=12 if you wish to use individual parameters
NOTICE
Danger of collision!
The thread is generated to the length of the reference element.
The control does not check for collisions with the workpiece
contour (e.g. contour of the finished part). Danger of collision
during machining!
Another linear element without undercut is to be
programmed as overrun.
