4.3 Grooving cycle – CYCLE93
1st step
Paraxial roughing to the base of the groove in single
infeed steps. After each infeed, the tool is retracted
for chip breaking.
2nd step
The groove is machined perpendicular to the infeed
direction in one or more cuts. Each cut is again
divided up according to the infeed depth. From the
second cut along the groove width the tool is
withdrawn by 1 mm before it is fully retracted.
3rd step
Cutting of the flanks in one step, if angles are
programmed under ANG1 or ANG2. The infeed
along the groove width is performed in several steps
if the flank width is larger.
