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.
Path overlap factor
Q370: Q370 x tool radius =
stepover factor k. Maximum input value: 1.9999
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.
Feed rate for finishing
Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
