    It's all about where you direct your force. if you can direct it in a direction that is stronger, you can then feed faster.

    THe original video is cool, never seen anything like it. I bet that would be great for turning crankshaft journals, or other bearing surfaces deep between sidewalls. it allows a MUCH stouter tool to be used.

    I've already tried that sort of thing.

    Yeah, stiffer tool. Basically zero overhang from the tool itself and no flex.

    why would that be faster, or the y-axis parting?

    Lathe Skiving is kind of related process:

    Now I have to admit that I never thought of that!

    Or power skiving that looks almost like cut knurling:

    Bet that would make nice knurling every time without buggering the start!

    dang

    looks like a shear tool that they rotate slightly to use a fresh part of the blade for every bit of the cut.
