Abstract:
Belt grinding machine with multiaxis computer number control(CNC) system can effectively process parts with complex moulding surfaces.In this paper,isoparametric and isoplanar tool path planning strategies customized for this kind of machine are proposed.The tool path generation methods are designed based on the analysis of the belt grinding process.By using least square method,optimized cross section normal is computed in the isoplanar method.To improve the design efficiency of path planning,reduce experiments and increase economical benefit,the geometric simulation program based on linear grinding model is developed.Experiment on a turbine blade profile shows that the proposed algorithms work satisfyingly.
