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 slot.
U U U U Feed rate for milling Q207: Traversing speed of the
tool in mm/min while milling.
U U U U Plunging depth Q202 (incremental value): Total
extent by which the tool is fed in the tool axis during
a reciprocating movement.
U U U U Machining operation (0/1/2) Q215: Define the
machining operation:
0. Roughing and finishing
1. Only roughing
2. Only finishing
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):
Z coordinate 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 slot in the reference axis of the working plane.
U U U U Center in 2nd axis Q217 (absolute value): Center of
the slot in the minor axis of the working plane.
U U U U Pitch circle diameter Q244: Enter the diameter of
the pitch circle.
U U U U Second side length Q219: Enter the slot width. If you
enter a slot width that equals the tool diameter, the
TNC will carry out the roughing process only (slot
milling).
U U U U Starting angle Q245 (absolute value): Enter the polar
angle of the starting point.
U U U U Angular length Q248 (incremental value): Enter the
angular length of the slot.
Not available with TNC 410:
U U U U Infeed for finishing Q338 (incremental value):
Infeed per cut. Q338=0: Finishing in one infeed.
