Input data
l
SET-UP CLEARANCE WOO (incremental value)
Distance between tool tip and workpiece
surface. Enter a positive value.
l
DEPTH 0201 (incremental value):
Distance between workpiece surface and
bottom of slot. Enter a negative value.
l
FEED RATE FOR MILLING Q207:
Traversing speed of the tool when milling in
mm/min.
l
PECKING DEPTH Q202 (incremental value):
Total extent by which the tool is fed in during a
reciprocating movement in the tool axis. Enter a
positive value.
l
MACHINING OPERATION (01112) 0215:
Specify extent of machining:
0: Roughing and finishing
1: Roughing only
2: Finishing only
l
WORKPIECE SURFACE COORDINATE Q203
(absolute value):
Coordinate of the workpiece surface.
. 2ND SET-UP CLEARANCE Q204
(incremental value):
Z coordinate at which no collision between tool
and workpiece (clamping devices) can occur.
Enter a positive value.
l
CENTER IN 1ST AXIS Q216 (absolute value):
Center of the slot in the main axis of the working
plane.
l
CENTER IN 2ND AXIS Q217 (absolute value):
Center of the slot in the secondary axis of the
working plane.
l
FIRST SIDE LENGTH Q218 (value parallel to
the main axis of the working plane):
Enter the length of the slot.

l
SECOND SIDE LENGTH Q219 (value parallel to the secondary axis of
the working plane):
Enter the width of the slot. If you enter a slot width that equals the tool
diameter, the TNC will only carry out the roughing process (slot rough-
ing).
l
ANGiE OF ROTATION 0224 (absolute value):
Angle about which the entire slot is rotated. The center of rotation lies
in the center of the slot.
