Cycle parameters
Set-up clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Enter a
positive value. Input range 0 to 99999.9999
Depth Q201 (incremental): Distance between
workpiece surface and bottom of hole (tip of drill
taper). Input range -99999.9999 to 99999.9999
Feed rate for plunging Q206: Traversing speed of
the tool during drilling in mm/min. Input range 0 to
99999.999; alternatively
FAUTO, FU
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
Dwell time at top Q210: Time in seconds that the
tool remains at set-up clearance after having been
retracted from the hole for chip removal. Input range
0 to 3600.0000
Coordinate of workpiece surface Q203 (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
Dwell time at depth Q211: Time in seconds that
the tool remains at the hole bottom. Input range 0 to
3600.0000
