Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.
Depth Q201 (incremental value): Distance between
workpiece surface and bottom of stud.
Feed rate for plunging Q206: Traversing speed of
the tool in mm/min when moving to depth. If you are
plunge-cutting into the material, enter a low value; if
you have already cleared the stud, enter a higher feed
rate.
Plunging depth Q202 (incremental value): Infeed per
cut. Enter a value greater than 0.
Feed rate for milling Q207: Traversing speed of the
tool in mm/min while milling.
Workpiece surface coordinate Q203 (absolute
value): Coordinate of the workpiece surface.
2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
Center in 1st axis Q216 (absolute value): Center of
the stud in the reference axis of the working plane.
Center in 2nd axis Q217 (absolute value): Center of
the stud in the minor axis of the working plane.
1st side length Q218 (incremental value): Stud
length, parallel to the reference axis of the working
plane.
2nd side length Q219 (incremental value): Stud
length, parallel to the minor axis of the working plane.
Corner radius Q220: Radius of the stud corner.
Allowance in 1st axis Q221 (incremental value):
Allowance for pre-positioning in the reference axis of
the working plane referenced to the length of the
stud.
