ú Set-up clearance Q200 (incremental value):
Distance between tool tip and workpiece surface.
ú Depth Q201 (incremental value): Distance between
workpiece surface and bottom of pocket
ú 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 pocket, enter
a higher feed rate.
ú Plunging depth Q202 (incremental value):
Infeed per cut; enter a value greater than 0.
ú Feed rate for milling Q207: Traversing speed of the
tool in mm/min while milling.
ú Workpiece surface coordinate Q203 (absolute
value): Coordinate of the workpiece surface
ú 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices)
can occur.
ú Center in 1st axis Q216 (absolute value): Center of
the pocket in the main axis of the working plane
ú Center in 2nd axis Q217 (absolute value): Center of
the pocket in the secondary axis of the working
plane
ú First side length Q218 (incremental value): Pocket
length, parallel to the main axis of the working
plane
ú Second side length Q219 (incremental value):
Pocket length, parallel to the secondary axis of the
working plane
ú Corner radius Q220: Radius of the pocket corner If
you make no entry here, the TNC assumes that the
corner radius is equal to the tool radius.
ú Allowance in 1st axis Q221 (incremental):
Allowance in the main axis of the working plane
referenced to the length of the pocket. This value is
only required by the TNC for calculating the
preparatory position.
