Description
l Enter here the length of the end face to be cut, taking the contour start position
("Reference z0") in the longitudinal axis (Z axis) as the starting point.
d1 External diameter of the end face to be cut (absolute position of the X axis in the
diameter).
d2 Internal diameter of the end face to be cut (absolute position of the X axis in the
diameter).
m1 Enter the maximum infeed depth for roughing. The internal infeed calculation
ensures that the infeed is as uniform as possible throughout the roughing operation.
This entry value represents the maximum value possible and is therefore not
exceeded.
m2 Finishing allowance in the X axis (m2x)
Finishing allowance in the Z axis (m2z)
