Programming example: Thread cutting
By using this program, you can produce a metric external thread M42x2 with flank infeed.
Infeed is carried out with constant cutting cross-section. At the end of thread a cut out of 7
mm is defined. 5 roughing cuts are carried out at a thread depth of 2.76 mm without finishing
allowance. At completion of this operation, two idle passes will be carried out.
