    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.

    "Commonly" found items that contain magnesium (metal)?

    Fresh titanium chips will burn as well. If you can come into some stringy lathe chips you might be set.

    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.

    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...

    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.)
