G 84

Exampie for the machining of a thread with G84 : The following feed increments are programmed :

1	feed with	0.25	mm	(N24)
4	f eeds with	0.3	mm	(N25)
1	feed with	0.195	nur.	(N26)
1	feed with	0.097	mm	(N26)
2	feeds with	0.049	mm	(N26)

Programming for machlning with straight-line feed (both thread flanks are machined at the same time) :
