Description
Unit
Position of the thread:
• Internal thread
An internal thread is cut.
• External thread
An external thread is cut.
NT Number of teeth per cutting edge
Single or multiple toothed milling inserts can be used. The motions required are
executed by the cycle internally, so that the tip of the bottom tooth on the milling
tool cutting edge corresponds to the programmed end position when the thread
end position is reached. Depending on the cutting edge geometry of the milling
insert, the retraction path must be taken into account at the base of the work-
piece.
