Modeling and Predicting Cross-sectional Surface Roughness for the Grinding Process

Abstract

Abstract. This paper proposes a new algorithm for predicting the cross-sectionalsurface roughnesst of the workpiece for the grinding process, which reduces three-dimensional modeling to two-dimensional modeling by virtue of the cross-sectional area of the undeformed grinding chip. Besides, this paper develops a search technique to figure out systematically the surface roughness in order to determine the final cross-sectional surface roughness produced by thousands of grinding wheel grains with randomly distributed protrusion heights. The simulated results are consistent with the measurement data,which proves the effectiveness of the proposed algorithm.
