The machining sequence is as follows:
1. Starting from the current axis position, the first calculated groove position is approached
2. Execute the depth infeeds as a roughing motion in the transverse axis (X axis): each

Description
t This value is the groove depth which together with the value for "Diameter d" specifies
the absolute position of the base of the groove.
F1 Depending on the option selected, this value forms either an input radius (display
"Radius RND") or an input chamfer (display "Chamfer CHF") of less than 45
sides of the groove. You can toggle between RND / CHF using the toggle key. An input
value of 0.0 switches this function off.
F2 Depending on the option selected, this value forms either a radius (display "Radius
RND") or a chamfer (display "Chamfer CHF") of less than 45
groove as the transition to the base of the groove. You can toggle between RND / CHF
using the toggle key. An input value of 0.0 switches this function off.
m1 Enter the maximum infeed depth for roughing during grooving. The cycle's internal
infeed calculation ensures that this input value is not exceeded during machining.
m2 Finishing allowance perpendicular to the contour.
In this toggle field you can select whether an internal or an external groove is required.
The selection is indicated by a diagram on the screen.

infeed depth is calculated internally so that firstly the setting "m1" is not exceeded and
