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 slot.
8
Feed rate for milling
Q207: Traversing speed of the
tool in mm/min while milling.
8
Plunging depth
Q202 (incremental value): Total
extent by which the tool is fed in the tool axis during
a reciprocating movement.
8
Machining operation (0/1/2)
Q215: Define the
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing
8
Workpiece surface coordinate
Q203 (absolute
value): Coordinate of the workpiece surface.
8
2nd set-up clearance
Q204 (incremental value):
Z coordinate at which no collision between tool and
workpiece (clamping devices) can occur.
8
Center in 1st axis
Q216 (absolute value): Center of
the slot in the reference axis of the working plane.
8
Center in 2nd axis
Q217 (absolute value): Center of
the slot in the minor axis of the working plane.
8
1st side length
Q218 (value parallel to the reference
axis of the working plane): Enter the length of the slot
8
2nd side length
Q219 (value parallel to the secondary
axis of the working plane): 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).
8
Angle of rotation
Q224 (absolute value): Angle by
which the entire slot is rotated. The center of rotation
lies in the center of the slot.
8
Infeed for finishing
Q338 (incremental value):
Infeed per cut. Q338=0: Finishing in one infeed.
8
Feed rate for plunging
Q206: Traversing speed of
the tool while moving to depth in mm/min. Effective
only during finishing if infeed for finishing is entered.
