NOTE
5 The tool returns to the cycle start point (cutting depth Δd
n
) as soon as the feed hold status is entered
during thread cutting when the "Thread Cutting Cycle retract" option is used.(Δd
n
: cutting depth in nth
cut)
6 If start point of thread cutting cycle is close to a workpiece, tool may interfere with the workpiece during
retract cycle because of passing along the retract cycle route described at Note 5. Therefore start point
of thread cutting cycle must be at least k(height of thread) away from the top of thread when the
"Thread Cutting Cycle retract" option is used.
