    Right.

    Pretty much 1/8-27 isn't "Oilfield" stuff. Not to say it doesn't exist out there, but it's to lubricate the real work.

    The C-axis feels "jerky"? That's not good, it'll make it very difficult to Mill parts.

    It vibrates when you jog it too? Does it vibrate when you give it a programmed feedrate?

    Why would that matter? I mean we've basically derailed the OP's thread, but why would the manner of determining feedrate make any difference?

    It is tedious. Were it me, I would just long hand 3 or 5 Rough passes from the OD, then a Finish pass. I wouldn't use G75 for such a small Groove.

    But I'm probably wrong, while you are probably right. No matter.
