Looking at this print, material is CRS, tolerances are open, with the only really critical feature being the sharp corner called out by the asterisk.
The 1.07 and 0.85 dimensions are full radius slots, if that isn't clear, and the 0.85 horizontal dimension is to a small flat. The radii in the left hand view that aren't called out measure 0.140.
Since I have to finish these in the mill (Haas VMC) anyway, I had planned on doing the whole thing there, especially because I'm not super comfortable or confident with working those inside corners sharp on my manual lathe. I figured on doing the majority of the material removal with a straight EM, then coming back in with a reduced shank EM to do the .110 on a side undercut portion.
Is this more trouble than it's worth? Should I just suck it up and go for it on the lathe?
I'll have about 20 PCS to do at a time, maybe a hundred or so a year total, so I can probably make an undercut EM go a long way (assuming I can find the one I'm looking for - I haven't had any luck finding one that's got 1/8" on a side step out with a short enough flute length. I'm not crazy about grinding the shank down on a tool (because I'm not very good at it) but have skated by with it in the past.
Any other ideas or thoughts? Is there something stupid and simple that I'm missing?
Thanks
