U U U U Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.
U U U U Workpiece surface coordinate Q203 (absolute
value): Absolute coordinate of the workpiece surface
U U U U 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
U U U U Plunging strategy Q366: Type of plunging strategy.
n 0 = vertical plunging. In the tool table, the plunging
angle ANGLE for the active tool must also be defined
as 0. The TNC will otherwise display an error
message.
n 1 = helical plunging. In the tool table, the plunging
angle ANGLE for the active tool must be defined not
equal to 0. The TNC will otherwise display an error
message.
