Cycle parameters
U
Set-up clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999
U
Depth Q201 (incremental): Distance between
workpiece surface and bottom of hole. Input range
-99999.9999 to 99999.9999
U
Feed rate for plunging Q206: Traversing speed of
the tool during boring at mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU
U
Dwell time at depth Q211: Time in seconds that the
