Configuring cycles
Enter the finishing feedrate for complete ma‐
chining, roughing and finishing. The percent‐
age of the value corresponds to that entered
under parameter F (feedrate).
Dwell time, which is necessary between
grooving and retracting for grooving technol‐
ogy. Tool clearance time during grooving at
the base.
Angle, through which the tool is lifted from
the contour for contour turning, roughing.
Amount, by which the tool is lifted when
roughing a contour taking into account the
retraction angle SD55580
$SCS_TURN_CONT_RELEASE_ANGLE.
This also applies to stock removal, grooving
and plunge turning.
