Machining type, rough finishing
If there is too much residual material on the slot walls, unwanted corners are removed to the
finishing dimension.
Machining type, finishing:
When finishing walls, the milling cutter travels along the slot walls, whereby just like for
roughing, it is again fed in the Z direction, increment by increment. During this process, the
milling cutter travels through the safety clearance beyond the beginning and end of the slot,
so that an even slot wall surface can be guaranteed across the entire length of the slot.
Machining type, edge finishing
Edge finishing is performed in the same way as finishing, except that the last infeed (finish
base) is omitted.
Machining type, finishing base:
When finishing the base, the milling cutter moves backwards and forwards once in the
finished slot.
Machining type, chamfering
Chamfering involves breaking the edge at the upper slot edge.
