Cycle parameters
Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface Input range
0 to 99999.9999
Q201 Depth? (incremental): Distance between
workpiece surface and bottom of hole. Input range
-99999.9999 to 99999.9999
Q206 Feed rate for plunging?: Traversing speed of
the tool in mm/min during reaming. Input range 0 to
99999.999, alternatively FAUTO, FU
Q211 Dwell time at the depth?: Time in seconds
that the tool remains at the hole bottom. Input range
0 to 3600.0000
Q208 Feed rate for retraction?: Traversing speed
of the tool in mm/min when retracting from the
hole. If you enter Q208 = 0, the feed rate for
reaming applies. Input range 0 to 99999.999
Q203 Workpiece surface coordinate? (absolute):
Coordinate of the workpiece surface. Input range 0
to 99999.9999
Q204 2nd set-up clearance? (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
