 Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface. Enter a
positive value.
 Select Depth/Diameter (0/1) Q343: Select whether
centering is based on the entered diameter or depth.
If centering is based on the entered diameter, the
point angle of the tool must be defined in the T-ANGLE
column of the tool table TOOL.T.
 Depth Q201 (incremental value): Distance between
workpiece surface and centering bottom (tip of
centering taper). Only effective if Q343=0 is defined.
 Diameter (algebraic sign) Q344: Centering
diameter. Only effective if Q343=1 is defined.
 Feed rate for plunging Q206: Traversing speed of
the tool during centering in mm/min.
 Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom.
 Workpiece surface coordinate Q203 (absolute
value): Coordinate of the workpiece surface.
 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
