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.
When roughing in CYCLE95, you can choose between
"with rounding" or "without rounding" at the contour in
SW 6.2 and higher. For doing so, the HUNDREDS
DIGIT is implemented in parameter VARI.
A plausibility check is performed on parameter VARI. If
you select an invalid value, the cycle is aborted and
alarm 61002 "Wrong machining type defined" is put out.
