Description
Enter the length of the "step" to be produced, taking the contour start position ("Reference
z0") in the axial axis (Z axis) as the starting point.
Interpolation point position, which defines the position of the additional contour interpolation
point in the longitudinal axis (Z axis).
Outside diameter of the "step" to be machined in the radial axis (absolute position of the X
axis in the diameter).
Interpolation point diameter, which together with the "Interpolation point position l2"
parameter defines the position of the interpolation point in the radial axis (absolute position
of the X axis in the diameter), allowing beveled faces to be produced within a "step".
Inside diameter of the "step" to be machined in the radial axis (absolute position of the X
axis in the diameter).
Depending on the option selected, this value forms either a transition radius (display "RND")
or a transition chamfer (display "Chamfer CHR" or "Chamfer CHF") of less than 45
between the end face and the inside diameter of the "step". You can toggle between RND /
CHR / CHF using the toggle key. An input value of 0.0 switches this function off.
Two types of dimensioning are possible with the chamfers:
in the case of chamfer CHR, the value specifies the width of the chamfer in the direction
•
of the movement,
in the case of chamfer CHF, the value corresponds with the length of the chamfer.

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.
