8
Set-up clearance
Q200 (incremental value): Distance
between tool tip and workpiece surface.
8
Depth
Q201 (incremental value): Distance between
workpiece surface and bottom of pocket.
8
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 value lower
than that defined in Q207.
8
Plunging depth
Q202 (incremental value): Infeed per
cut. Enter a value greater than 0.
8
Feed rate for milling
Q207: Traversing speed of the
tool in mm/min while milling.
8
Workpiece surface coordinate
Q203 (absolute
value): Coordinate of the workpiece surface.
8
2nd set-up clearance
Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
8
Center in 1st axis
Q216 (absolute value): Center of
the pocket in the reference axis of the working plane.
8
Center in 2nd axis
Q217 (absolute value): Center of
the pocket in the minor axis of the working plane.
8
First side length
Q218 (incremental value): Pocket
length, parallel to the reference axis of the working
plane.
8
Second side length
Q219 (incremental value): Pocket
length, parallel to the minor axis of the working plane
8
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.
8
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
pocket.
