78 Fixed Cycles: Drilling
3.4 REAMING (Cycle 201, DIN/ISO: G201)
Cycle parameters
U Setup clearance Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999, alternatively PREDEF
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 reaming in mm/min. Input range: 0 to
99999.999; alternatively FAUTO, FU.
U Dwell time at depth Q211: Time in seconds that the
tool remains at the hole bottom. Input range 0 to
3600.0000, alternatively PREDEF
U 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. Input range 0 to 99999.999
U Workpiece surface coordinate Q203 (absolute):
Coordinate of the workpiece surface. Input range 0 to
99999.9999
U 2nd setup clearance Q204 (incremental): Coordinate
in the spindle axis at which no collision between tool
and workpiece (fixtures) can occur. Input range 0 to
99999.9999, alternatively PREDEF
