Use millimeters a lot in CNC, as a lot of components are made in metric units, and dimensions always stated in millimeters. Though for my "work" I wouldn't use anything but Imperial units... force of habit maybe, but works just fine. Interestingly, the controls are set up for Imperial units on my CNCs, though the leadscrews are mm.
