Metal cutting burr formation is a highly complicated behavior of material deformation. The formation of burr on precision parts directly influence the edge quality, so it is very necessary to study burr controlling and prediction systematically. There are many factors that influence the formation of burr, it is very difficult to model burr formation process in 3D oblique cutting. This article introduces the method of establishing a mathematical mechanical model of two side direction burr formation process based on the orthogonal cutting, the development and application of burr control chart and burr expert system. Finally, it is suggested that the standardization of burr must be carried out.
