U Setup clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999, alternatively PREDEF
U Workpiece surface coordinate Q203 (absolute):
Absolute coordinate of the workpiece surface. Input
range -99999.9999 to 99999.9999
U 2nd setup 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
U 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.
„ Alternative: PREDEF
