 Infeed depth for chip breaking Q257 (incremental):
Depth at which the TNC carries out chip breaking. No
chip breaking if 0 is entered. Input range 0 to
99999.9999
 Retraction rate for chip breaking Q256
(incremental): Value by which the TNC retracts the
tool during chip breaking. The TNC retracts the tool at
a feed rate of 3000 mm/min. Input range 0.1000 to
99999.9999; alternatively PREDEF
 Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom. Input range 0 to
3600.0000; alternatively PREDEF
 Deepened starting point Q379 (incremental with
respect to the workpiece surface): Starting position of
drilling if a shorter tool has already pilot drilled to a
certain depth. 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 after the
machining operation. If you enter Q208 = 0, the TNC
retracts the tool at the feed rate Q207. Input range 0
to 99999.999; alternatively FMAX, FAUTO, PREDEF
 DEPTH REFERENCE Q395: Select whether the entered
depth is referenced to the tool tip or the cylindrical
part of the tool. If the TNC is to reference the depth
to the cylindrical part of the tool, the point angle of the
tool must be defined in the T ANGLE column of the
tool table TOOL.T.
0 = Depth referenced to tool tip
1 = Depth referenced to the cylindrical part of the tool
