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
