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. 5 roughing cuts and one noncut
are performed.
The machining type defined is longitudinal, outside,
with constant cross-section of cut.
