Programming example for
thread cutting
Cut circular pocket in a solid blank and cut a thread.
The milling tool cannot cut across center. The circular pocket will
therefore have to be predrilled with a Ø22mm drill. The milling tool can
then be inserted centrally.
Using position patterns, the positions of the above-mentioned cycles
can be programmed (see Sec. "Using position patterns in milling").
