Put a couple of handwheel encoders on it and you could operate it just
like a manual. I run our Sugami CNC with the manual hand wheel all the
time for one off parts. All the tooling is already set up. MDI is also
an easy way to go too, especially if you have some macros for bolt
circles and the whole boatload of g codes. As someone said recently,
you got to think outside the box to get things done.

I think that even one off things, are best handled with G
codes. Mostly, for hand control, I only see repair applications like
"drill out this broken bolt" or some such.

I use CNC to drill even one hole. Turn on computer, start control, click
"Home", put part in vice, bring up drill.job to edit and put in coords. of
holes, put drill in machine, zero Z axis, click cycle start. You're done.
Its a push on CNC vs. manual on one hole, do two and CNC is more accurate
and faster.
