Infeed is always performed in the facing axis with
longitudinal machining and in the longitudinal axis
with face machining.
Outside machining means that infeed is performed
in the direction of the negative axis. In inside
machining, infeed is performed in the direction of the
positive axis.
A plausibility check is performed on parameter VARI.
If its value does not lie within the range 1 ... 12 when
the cycle is called, the cycle is aborted with alarm
61002 "Machining type incorrectly programmed".
