Has anyone had any experience inspecting on cnc machine tools vs CMM?
seems like a good efficieincy improvement, is there a downside?

It can work pretty well, but there is an issue with calibrating and assuring accuracy of the NC machine tool.

typically the NC machine is checked and calibrated annually as a piece of inspection equipment.

Also, the inspection portion of the NC program needs to be validated and put under change control.

Good luck

A key to accurate measurement is that the gage and the part need to be clean. Do do not want to measure chips, coolant, etc. If this can be assured, then you have a good chance of good measurement. Of course, you have a tool to determine the adequacy of such a measuring system - do a Gage R & R (or at least a gage R).
