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.
