Awl--
If yer pocketing a circle, it dawned on me that there is no easy way to feather in/out, to avoid undue marks/divets.
afaict, The only real way would be entry/exit spirals. See wiki for examples, proly the Archimedian spiral being the most practical AND suitable.
Does anyone have a macro to do this? Do some machines have canned cycles to do this?
I would imagine cadcam allows this, eh? :( I guess jb would know all about this....
In lieu of this, I guess I'll just do the regular g3, in rough and a second very fine finish pass.
What do others do?
My application is really not that critical now, but at some point it would be nice to do this--in production, this certainly would seem to be a time saver, visavis a second pass.
