Set-up clearance
Q200 (incremental value): Distance
between tool tip and workpiece surface.
8
Workpiece surface coordinate
Q203 (absolute
value): Absolute coordinate of the workpiece surface
8
2nd set-up clearance
Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
8
Path overlap factor
Q370: Q370 x tool radius =
stepover factor k.
8
Plunging strategy
Q366: Type of plunging strategy.
0 = vertical plunging. In the tool table, the plunging
angle ANGLE for the active tool must be defined as
90°. Otherwise the TNC displays an error message.
1 = helical plunging. In the tool table, the plunging
angle ANGLE for the active tool must be defined not
equal to 0. Otherwise the TNC displays an error
message.

Feed rate for finishing
Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
