The rotation accuracy of the aerostatic spindle can easily be affected by shaft shape errors due to small gas film clearance. Thus, main with largest scale—that is, roundness and cylindricity errors—are studied in this paper, a dynamic mathematical model is established consideration roundness, errors, speed. In order construct model, discrete coefficient index radius based on measurement data a...
