Note
The cycle requires a milling cutter with an "end tooth cutting across center" (DIN844).
Function
Use this cycle to machine long holes located on a circle. The longitudinal axis of the long holes is aligned radially.
In contrast to the slot, the width of the long hole is determined by the tool diameter.
Internally in the cycle, an optimum traversing path of the tool is determined, ruling out unnecessary idle passes. If several
depth infeeds are required to machine a slot, the infeed is carried out alternately at the end points. The path to be traversed
along the longitudinal axis of the long hole changes its direction after each infeed. The cycle searches for the shortest path
when changing to the next long hole.
