Climb or up-cut Q351: Type of milling operation
with M3
+1 = climb
–1 = up-cut
PREDEF: The TNC uses the value from the GLOBAL
DEF block
Depth Q201 (incremental): Distance between
workpiece surface and bottom of slot. Input range
-99999.9999 to 99999.9999
Plunging depth Q202 (incremental): Infeed per
cut. Enter a value greater than 0. Input range 0 to
99999.9999
Finishing allowance for floor Q369 (incremental
value): Finishing allowance in the tool axis. Input
range 0 to 99999.9999
Feed rate for plunging Q206: Traversing speed of
the tool while moving to depth in mm/min. Input
range 0 to 99999.999; alternatively FAUTO, FU, FZ
Infeed for finishing Q338 (incremental): Infeed per
cut. Q338=0: Finishing in one infeed. Input range 0
to 99999.9999
Set-up clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999, alternatively PREDEF
Coordinate of workpiece surface Q203 (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
2nd set-up clearance Q204 (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999, alternatively PREDEF
Plunging strategy Q366: Type of plunging strategy:
0: vertical plunging. The plunging angle (ANGLE) in
the tool table is not evaluated.
1, 2: reciprocal plunging. In the tool table, the
plunging angle ANGLE for the active tool must be
defined as not equal to 0. Otherwise, the TNC
generates an error message
PREDEF: The TNC uses the value from the GLOBAL
DEF block
Feed rate for finishing Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
Input range 0 to 99999.999; alternatively FAUTO,
FU, FZ
