In longitudinal machining, the infeed is always carried out along the transversal axis, and in face machining - along the
longitudinal axis.
For external contour, carry out the infeed in the negative direction of the axis; for internal contour, carry out the infeed in the
positive direction of the 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".
