U U U U Machining operation (0/1/2) Q215: Define the
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing
Side finishing and floor finishing are only executed if
the finishing allowances (Q368, Q369) have been
defined.
U U U U Slot length Q218 (value parallel to the reference axis
of the working plane): Enter the length of the slot
U U U U Slot width 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 U U U Finishing allowance for side Q368 (incremental
value): Finishing allowance in the working plane.
U U U U Angle of rotation Q224 (absolute): Angle by which
the entire slot is rotated. The center of rotation is the
position at which the tool is located when the cycle is
called.
U U U U Slot position (0/1/2/3/4) Q367: Position of the slot
in reference to the position of the tool when the cycle
is called (see figure at center right):
0: Tool position = Center of slot
1: Tool position = Left end of slot
2: Tool position = Center of left slot circle
3: Tool position = Center of right slot circle
4: Tool position = Right end 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 Climb or up-cut Q351: Type of milling operation with
M03.
+1 = climb milling
–1 = up-cut milling
Enter in MP7441 bit 2 whether the TNC should output an
error message (bit 2=1) or not (bit 2=0) if a positive depth
is entered.
Danger of collision!
Keep in mind that the TNC reverses the calculation for pre-
positioning when a positive depth is entered. This
means that the tool moves at rapid traverse in the tool axis
at safety clearance below the workpiece surface!
