Thread lead 2 as a value (enter without sign)
Thread lead 3 as a value (enter without sign)
VARI INT Definition of the machining type for the thread
Number of threads (enter without sign)
Variable retraction path based on initial diameter, incremental (enter without sign)
This cycle can be used to produce several cylindrical or tapered threads in succession. The individual thread sections can
have different leads whereby the lead within one and the same thread section must be constant.
See the following illustration for CYCLE97:
Sequence
Position reached prior to cycle start:
Starting position is any position from which the programmed thread starting point and run-in path can be approached without
collision.
The cycle creates the following sequence of motions:
● Approach of the starting point determined in the cycle at the beginning of the run-in path for the first thread turn with G0
● Infeed for roughing according to the infeed type defined under VARI.
● Thread cutting is repeated according to the programmed number of roughing cuts.
● The finishing allowance is removed in the following step with G33.
● This step is repeated according to the number of idle passes.
● The whole sequence of motions is repeated for each further thread turn.
