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
velocity of the tool during positioning from the set-
up clearance to a 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
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 99999.9999, alternatively
FMAX,FAUTO
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 the tool tip
1 = Depth referenced to the cylindrical part of the
tool
