Long hole (LONGHOLE) - only for G code program
Function
In contrast to the groove, the width of the elongated 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 an elongated hole,
the infeed is carried out alternately at the end points. The path to be traversed in the plane along
