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
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
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
Plunging strategy Q366: Type of plunging strategy:
0
= vertical plunging. The TNC plunges
perpendicularly, regardless of the plunging angle
ANGLE defined in the tool table
1 = No function
2 = reciprocating plunge. In the tool table, the
plunging angle ANGLE for the active tool must be
defined as not equal to 0. The TNC will otherwise
display an error message
