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. 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
 Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom. 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
 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 set-up
clearance to the deepened starting point. Input range
0 to 99999.9999
 Feed rate for pre-positioning Q253: Traversing
speed of the tool in mm/min during positioning from
set-up clearance to the deepened starting point.
Effective only if the value entered for Q379 is not
equal to 0. Input range 0 to 99999.999; alternatively
FMAX
, FAUTO, PREDEF
 Feed rate for retraction 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
drilling feed rate Q206. Input range 0 to 99999.999;
alternatively FMAX, FAUTO, PREDEF
