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.
