Cycle parameters
 Set-up clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Enter a
positive value. Input range 0 to 99999.9999;
alternatively PREDEF
 Depth Q201 (incremental): Distance between
workpiece surface and bottom of hole (tip of drill
taper). 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
 Plunging depth Q202 (incremental): Infeed per cut.
Input range 0 to 99999.9999. The depth does not
have to be a multiple of the plunging depth. The TNC
will go to depth in one movement if:
 the plunging depth is equal to the depth
 the plunging depth is greater than the depth
 Dwell time at top Q210: Time in seconds that the
tool remains at set-up clearance after having been
retracted from the hole for chip removal. 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
 Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom. Input range 0 to
3600.0000; 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
