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, that is, parallel to the
cone at which the groove is machined. During this process, a safety clearance to the contour is calculated by the cycle
internally.
Step 1
Paraxial roughing down to the base of the groove in single infeed steps.
After each infeed, the tool is retracted for chip breaking.
