HEIDENHAIN ITNC 530 User Manual page 310

Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.
Depth Q201 (incremental value): Distance between
workpiece surface and bottom of hole.
Feed rate for plunging Q206: Traversing speed of
the tool during reaming in mm/min.
Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom.
Retraction feed rate Q208: Traversing speed of the
tool in mm/min when retracting from the hole. If you
enter Q208 = 0, the tool retracts at the reaming feed
rate.
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.
