 Feed rate for milling
Q207: Traversing speed of the
tool during milling in mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU, FZ
 Climb or up-cut Q351: Type of milling operation with
M3:
+1 = climb milling
–1 = up-cut milling
Alternatively PREDEF
 Depth
Q201 (incremental): Distance between
workpiece surface and bottom of stud. Input range
-99999.9999 to 99999.9999
 Plunging depth
Q202 (incremental): Infeed per cut.
Enter a value greater than 0. Input range 0 to
99999.9999
 Feed rate for plunging Q206: Traversing speed of
the tool while moving to depth in mm/min. Input
range 0 to 99999.999; alternatively FMAX, FAUTO, FU, FZ
 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
 Approach position (0...4)
Q437: Specify the tool
approach strategy:
0 : From the right of the stud (default setting)
1 : Lower left corner
2 : Lower right corner
3 : Upper right corner
4 : Upper left corner
If approach marks should be appear on the stud
surface during approach with the setting Q437=0,
then choose another approach position
