 Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.
 Workpiece surface coordinate Q203 (absolute
value): Absolute coordinate of the workpiece surface
 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
 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 = helical plunging. 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. Plunge on a helical path only if there
is enough space.
„ 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. The TNC can only plunge
reciprocally once the traversing length on the
circular arc is at least three times the tool diameter.
 Feed rate for finishing Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
