Grinding Parameter Optimization of Conical Drill Point Grinding Method

The conical grinding method has four grinding parameters, and for three drill point geometric parameters, the lip clearance angle, chisel edge angle and point angle, the flank configuration is not unique. So one more drill point geometric parameter is needed, such as heel clearance angle, chisel edge clearance angle. Using the supplementary parameter, the four geometric parameters can determine the four grinding parameters. To consider the effect of all the possible supplementary parameters together, the optimization method can be used to obtain a optimal solution,and the supplementary parameters and the grinding parameters are used as constrain conditions.
