Parameters Description Unit
Machining
∇ (roughing)
∇∇∇ (finishing)
Machining direction:
Z0 → Z1
Machining from top to bottom
Z1 → Z0
Machining from bottom to top
Direction of rotation of the thread:
Right-hand thread
A right-hand thread is cut.
Left-hand thread
A left-hand thread is cut.
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 insert
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 workpiece.
