 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 Steuerung.
 Use Q=12 if you wish to use individual parameters.
Danger of collision!
The thread is generated to the length of the reference
element. Another linear element without undercut is to be
programmed as overrun.
