Wandering what is the best way to program a chamfer on .0591 hole located on 22.5 deg. Slot. Running this on a Citizen K-16E. Material is 2024 Alum.

Thanks

I believe you could use G173 angular interpolation, but that would still require a holder normalized to 22.5 degrees.

I looked up the tooling configuration of a K16E and I cant tell if the bottom live tool can be set at an angle like a L type 8. If you cant normalize the tool to the angle, I dont know how you're going to get an even chamfer.

If you can normalize a spot drill to the chamfer, you could use G173 (at least its G173 for a L20E type 9). The code would be something close to G173 X0 Z.1 D22.5 (I just made up the Z number. the Z would be the intersection point of the hole's centerline and the angle. I just said Z.1 because it looks about 1/3 of the way down the part)

The G173 would make a virtual plane at 22.5 degrees that you could then program a normal G2/G3 X/Y chamfer.

How are you making the angled slot to begin with, and can you angle a tool holder at 22.5*? I can provide a better answer when I know that.

Also, since its not spec'd on the print, maybe just hand deburr if the quantities arent huge?
