Q201 (incremental value): Distance between

Plunging depth
Q202 (incremental value): Total
extent by which the tool is fed in the tool axis during
a reciprocating movement.

Machining operation (0/1/2)
Q215: Define the
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing

2nd set-up clearance
Q204 (incremental value):
Z coordinate at which no collision between tool and
workpiece (clamping devices) can occur.

Center in 1st axis
Q216 (absolute value): Center of
the slot in the reference axis of the working plane.

Center in 2nd axis
Q217 (absolute value): Center of
the slot in the minor axis of the working plane.

First side length
Q218 (value parallel to the
reference axis of the working plane): Enter the length
of the slot.
U
U
U
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).
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!
