I also made some parts that all the internal features were tapers into rads with nothing 'square' except the OD and back face. I don't know what other controls offer for canned cycle, so maybe a limitation in Fanuc, but not Siemens or Okuma, I don't know.īut really my whole issue is 'you never never need cam for a 2 axis lathe part' as a blanket statement is pretty brazen IMO. Not to mention typing all the crap in on a machine control. We have prints, and we could dim everything if needed, but still not sure if it is possible with a canned cycle or not as you would be grooving on an angle. 25 small dia (thru hole), roughly 40 grooves about. Maybe you could do them as we all know your superman on the lathe, but here we use cam to do all that work.Įdit: just looked at the last one, it is approx 4.5' deep, 1.6' large dia. Now we draw the tool, and they get stupid lxd ratios so we make them as large as possible, but we also need to verify (see the cam part there?) the bar will clear everything. AND since every 3 or 4 of these we cut we have to make a custom groove tool for, in cad. How would you use a canned cycle to generate internal grooves on an angle? OK maybe you come up with some fancy macro (I don't know if it's possible or not) BUT these grooves are not all the same depth, or on an equal spacing, so maybe 1 macro for each one, I dunno.

50' You have internal grooves perpindular to the tapered bore. You have a part with a tapered bore say 6-8' long, large end lets say 2'and small end.
