Inside out reamer?
My personal experience with 3D printed gears in PLA is to jam a twist drill through the center hole as fast as possible rather than try to use a straight flute reamer to bring the center hole to size. Might tell you something about the needed cutter geometry and chip load. -

Wire EDM & milling software
I have been pleased with Mastercam's WEDM programing with our Mitsubishi FX10. It has the Epacks built into the cut setup/selection and the speeds and feeds for the wire seem to be dead on straight from the post. On the milling side I have also been pleased with mastercam but I am using it to... -

Should a machinist do quoting for the owner of company?
From post #1 first 2 sentences: So a quick overview. I work for a smaller size fab shop with around 15 employees on the floor and I run the machining department myself as I am the only machinist there. I don't think they have 15 machines just for OP.- kenton

How to properly manually program chamfers and radii on a lathe
If you are using G41/G42 (tool nose radius compensation) make sure your are using the correct G code and have the correct tool nose radius values in your tool offsets. Then just program to the numbers. Some machines will let you program square corners and add a " ,R.03 " to add a .03 radius...- kenton

Angled saw cut on center.
Drill a hole on the center line of the part and halfway between the 2 faces. Then use that to line up the saw blade set at the correct angle. A fence could be set up for repeat jobs. If more accuracy is needed a saw might not be the correct tool. Maybe a horizontal mill with a slitting saw...- kenton

How to machine this internal keyway?
I have done similar on a 1/4" keyway using a lathe to shape the slot. I believe I used a .001 radial stepover, so it wasn't fast by any means. The ID groove should allow the chip to break. Just make sure to get the groove deburred. (FYI: that was a scrap part used for practice.) -
