8 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. Maximum input value: 1.9999
8 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 not
equal to 0. Otherwise the TNC displays an error
message.
8 Feed rate for finishing Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
Example: NC blocks
