Cycle parameters
U
Setup clearance
Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999, alternatively PREDEF
U
Depth
Q201 (incremental): Distance between
workpiece surface and bottom of hole. 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
Dwell time at depth
Q211: Time in seconds that the
tool remains at the hole bottom. Input range 0 to
3600.0000, alternatively PREDEF
U
Workpiece surface coordinate
Q203 (absolute):
Coordinate of the workpiece surface. Input range:
-99999.9999 to 99999.9999
U
2nd setup 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
U
Deepened starting point
Q379 (incremental with
respect to the workpiece surface): Starting position
for actual drilling operation. The TNC moves at the
feed rate for pre-positioning
from the setup
clearance to the deepened starting point. Input range
0 to 99999.9999
U
Feed rate for pre-positioning
Q253: Traversing
velocity of the tool during positioning from the setup
clearance to the deepened starting point in mm/min.
Effective only if Q379 is entered not equal to 0. Input
range 0 to 99999.999, alternatively FMAX, FAUTO,
PREDEF
U
Retraction feed rate
Q208: Traversing speed of the
tool in mm/min when retracting from the hole. If you
enter Q208 = 0, the TNC retracts the tool at the feed
rate in Q206. Input range 0 to 99999.999, alternatively
