The paper discusses the geometric characteristics of the roundness in grinding the inside grooves of the bearing, analyzing the effecting factors and the inter_relationships. The test factors of roundness modeling in grinding the inside grooves have been specified, test design has been conducted according to the hybrid perpendicularity, and the inter_effects of the factors have been considered. Through regressive modeling the test data progressively,the mathematics model between the grinding roundness and the process parameters has been established, and the effectiveness of the grinding parameters to the roundness have been visually displayed in 3D surface. Through further analyzing the mathematics model, several results with practical values have been gained.
