What are good ways to measure surface smoothness? It would be interesting sometime to attempt to cut a plane, and see what the error actually is, and somehow estimate what portion is quantization related, vibration related, calibration related, and simple actuator error related.
One test I can think of is to try to cut a "bowl", the inside of a hemisphere. I
would think a lot of motion artifacts would show up in that, especially stickiness
or backlash in the struts.
