uds and slots
U
Set-up clearance
Q200 (incremental value): Distance
between tool tip and workpiece surface.
U
Depth
Q201 (incremental value): Distance between
workpiece surface and bottom of slot
U
Feed rate for milling
Q207: Traversing speed of the
tool in mm/min while milling.
U
Plunging depth
Q202 (incremental value): Total
extent by which the tool is fed in the tool axis during
a reciprocating movement
U
Machining operation (0/1/2)
Q215: Define the
machining operation:
0
: Roughing and finishing
1
: Only roughing
2
: Only finishing
U
Workpiece surface coordinate
Q203 (absolute
value): Coordinate of the workpiece surface
U
2nd setup clearance
Q204 (incremental value):
Z coordinate at which no collision between tool and
workpiece (clamping devices) can occur
U
Center in 1st axis
Q216 (absolute value): Center of
the slot in the reference axis of the working plane
U
Center in 2nd axis
Q217 (absolute value): Center of
the slot in the minor axis of the working plane
U
First side length
Q218 (value parallel to the
reference axis of the working plane): Enter the length
of the slot
U
Second 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).
U
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.
U
Infeed for finishing
Q338 (incremental value):
Infeed per cut. Q338=0: Finishing in one infeed.
