 Set-up clearance
Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999; alternatively PREDEF
 Workpiece surface coordinate Q203 (absolute):
Absolute coordinate of the workpiece surface. Input
range -99999.9999 to 99999.9999
 2nd set-up clearance
Q204 (incremental): Coordinate
in the spindle axis at which no collision between tool
and workpiece (fixtures) can occur. Input range 0 to
99999.9999; alternatively PREDEF
 Path overlap factor
Q370: Q370 x tool radius =
stepover factor k. Input range 0.1 to 1.414;
alternatively PREDEF
 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.
 Alternative: PREDEF
 Feed rate for finishing
Q385: Traversing speed of
the tool during side and floor finishing in mm/min.
Input range 0 to 99999.999; alternatively FAUTO, FU, FZ
