I have a HAAS ST lathe with Y axis. I'm setting up some radial holes milled through hollow bar. I'm using a bull nose end mill which will let me do some edge deburring if I'm really dialed in with my movements to run the mill radius along the profile of the edge formed by the intersection of the milled hole and bar stock o.d. I can achieve this with a bunch of short XZY lines, but it would be a bit nicer with arcs. So, two options may exist or not: 1. I might be able to define a G2/G3 arc in a non orthogonal plane, if such a g code exists. 2. I might be able to just use3 dimensional line segments but with radius transitions to blend it out a bit. Does anybody know how to do this? NO, I do not have CAM and have no plan to acquire. I'm looking for basic approaches with G codes to mitigate hand deburring. Thx.
