 No. of breaks before retracting Q213: Number of
chip breaks after which the TNC is to withdraw the
tool from the hole for chip removal. For chip breaking,
the TNC retracts the tool each time by the value in
Q256. Input range 0 to 99999
 Minimum plunging depth Q205 (incremental): If you
have entered a decrement, the TNC limits the
plunging depth to the value entered with Q205. Input
range 0 to 99999.9999
 Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom. Input range 0 to
3600.0000; alternatively 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
feed rate Q206. Input range 0 to 99999.999;
alternatively FMAX, FAUTO, PREDEF
 Retraction rate for chip breaking Q256
(incremental): Value by which the TNC retracts the
tool during chip breaking. Input range 0.1000 to
99999.9999; alternatively 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
