Q204 2nd set-up clearance? (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
Q366 Plunging strategy (0/1/2)?: 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
Q385 Finishing feed rate?: Traversing speed of the
tool in mm/min during side and floor finishing. Input
range 0 to 99999.999, alternatively FAUTO, FU, FZ
Q439 Feed rate reference (0-3)?: Specify what the
programmed feed rate refers to:
0: Feed rate with respect to the tool center point
path
1: Feed rate with respect to the tool edge, but only
during side finishing, otherwise with respect to the
tool center point path
2: Feed rate refers to the tool cutting edge during
side finishing and floor finishing; otherwise it refers
to the tool path center
3: Feed rate always refers to the cutting edge
