Does anybody have any suggestions on what would be the best way to machine out helical profiles from a cylindrical stock? The stock is roughly 5 in. diameter and about 9in long. It seems that a Mill Multi Axis operation would be best but the Variable Guiding Curves op is more geared towards finishing as oppossed to roughing. Would idealy like to come through with a 1/2 - 5/8" tool.
Or if you can't push the cut strain in a way or another... or if your machine likes a bit of Fresh-Air HSM!
(play with rapid traverse (non-cutting moves))
For this case the Multi-Axis Roughing operation that would be released in 1899 (mid December) would work great. You can preview it with NX1872 and a template I can provide if you contact me in private. it supports Follow Part as well as Adaptive Pattern (5X version of the Adaptive milling we have for 3X). Ball / bull nose / Flat end mills and bottom up cutting to clean the ridges lefth on the part between the main cut levels.
