In longitudinal machining, the infeed is always carried out along the transversal axis, and in
face machining - along the longitudinal axis.
External machining means that the infeed is carried out in the direction of the negative axis.
With internal machining, the infeed is carried out in the direction of the positive axis.
The VARI parameter is subjected to a plausibility check. If its value is not in the range 1 ... 12
when the cycle is called, the cycle is aborted with alarm 61002 "Machining type defined
incorrectly".
