Aimed at the roundness evaluation, a regression analysis method evaluating the shape accuracy of the wrapped bearings was proposed. The analysis shows that the main influence parameters on the shape accuracy are thickness of powder and model clearance. Finally, the comparison test was carried out by a concrete example. The simulated results of the roundness are about consistent with the actual measurements and their discrepancy is only 0.025~0.057 mm.
