Function
The grooving cycle can be used to carry out symmetrical and asymmetrical grooves for
longitudinal and face machining at any straight contour elements. External and internal
grooves can be produced.
Sequence
The infeed in the depth (towards the groove base) and in the width (from groove to groove)
are calculated in the cycle internally and distributed equally with the maximum possible
value.
When grooving at oblique faces, the tool will traverse from one groove to the next on the
shortest path, i.e. parallel to the cone at which the groove is machined. During this process,
a safety clearance to the contour is calculated internally in the cycle.
1. Step
Paraxial roughing down to the base of the groove in single infeed steps.
After each infeed, the tool is retracted for chip breaking.
