Turning Cycles
4.8 Thread chaining – CYCLE98
Programming example
Thread chain
With this program you can produce a chain of
threads starting with a cylindrical thread. Infeed is
perpendicular to the thread. Neither a final
machining allowance nor a starting point offset have
been programmed. Five roughing cuts and one
noncut are performed.
The machining type defined is longitudinal, outside,
with constant cross-section of cut.
