I work with very small mill cutters at times, and if the table hiccups, 'bing' either the part or more usually the cutter is history.

John, to what advantage? a ball screw offers a number of advantages, but it does leap out at me what they'd be in this application. Backlash is one for example, not sure why reducing backlash would matter for the cross slide. And like Dave said, the cutting force could easily drive the screw. Unless...

Since seeing that thread I like the die cart - gotta be the most flexible solution to the problem. lift to height adjacent to machine and s...

thomas, A radius can readily be turned by what you describe; mapping out the x and y coordinates using Mr Pythagoras’s theory, turning a 'digital ' version of the curve (lots of little steps) than blending with a file.
