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 lower value
than that defined in Q207.
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.
