U U U U Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.
U U U U Depth Q201 (incremental value): Distance between
workpiece surface and bottom of stud.
U U U U 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.
U U U U Plunging depth Q202 (incremental value): Infeed per
cut. Enter a value greater than 0.
U U U U Feed rate for milling Q207: Traversing speed of the
tool in mm/min while milling.
U U U U Workpiece surface coordinate Q203 (absolute
value): Coordinate of the workpiece surface.
U U U U 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
U U U U Center in 1st axis Q216 (absolute value): Center of
the stud in the reference axis of the working plane.
U U U U Center in 2nd axis Q217 (absolute value): Center of
the stud in the minor axis of the working plane.
U U U U Workpiece blank diameter Q222: Diameter of the
premachined stud for calculating the pre-position.
Enter the workpiece blank diameter to be greater
than the diameter of the finished part.
U U U U Diameter of finished part Q223: Diameter of the
finished stud. Enter the diameter of the finished part
to be less than the workpiece blank diameter.
