Cycle parameters
Set-up clearance
Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999; alternatively PREDEF
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 in mm/min during drilling. 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 and no
chip breaking is defined
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tool remains at set-up clearance after having been
retracted from the hole for chip removal.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; alternatively PREDEF
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; alternatively PREDEF
Decrement
Q212 (incremental): Value by which the
TNC decreases the plunging depth Q202 after each
infeed. Input range 0 to 99999.9999
