Hello,
Im trying to O.D. thread a 1.250 x 12 on an LC-30 Okuma lathe with OSP 3000 controls. Currently im using a G33 but i am having some chatter issues. I would like to put a lead angle in the program. It calls for a G34 to do this. The book is pretty vague when it comes to calculating everything out. Here is a sample of the G33 that i am currently using:
G0G97S600T0606M3M8M44F833
N321 X36379Z55110
N322 Z54610
N323 X13500
N324 M23
N325 G86
N326 D0030E1000
N327 G33X11478Z44110I0F833
N328 G80
N329 G0
N330 M22
N331 G0X36379
N332 Z55110
N333 M9
N334 X120000
N335 M02
Any more questions please ask!!
Thank you in advance!!
