Cycle parameters
U Set-up clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999
U Depth Q201 (incremental): Distance between
workpiece surface and bottom of hole (tip of drill
taper). Input range -99999.9999 to 99999.9999
U Feed rate for plunging Q206: Traversing speed of
the tool during drilling in mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU
U Plunging depth Q202 (incremental): Infeed per cut.
Input range 0 to 99999.9999. The depth does not
have to be a multiple of the plunging depth. The TNC
will go to depth in one movement if:
„ the plunging depth is equal to the depth
„ the plunging depth is greater than the depth
U Workpiece surface coordinate Q203 (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
U 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
U Decrement Q212 (incremental): Value by which the
TNC decreases the plunging depth Q202. Input range
0 to 99999.9999
U Minimum plunging depth Q205 (incremental): If you
have entered a decrement, the TNC limits the
plunging depth to the value entered with Q205. Input
range 0 to 99999.9999
U Upper advanced stop distance Q258 (incremental):
Set-up clearance for rapid traverse positioning when
the TNC moves the tool again to the current plunging
depth after retraction from the hole; value for the first
plunging depth. Input range 0 to 99999.9999
U Lower advanced stop distance Q259 (incremental):
Set-up clearance for rapid traverse positioning when
the TNC moves the tool again to the current plunging
depth after retraction from the hole; value for the last
plunging depth. Input range 0 to 99999.9999
