Grinding Parameter Optimization of Conical Drill Point Grinding Method
-
摘要: 麻花钻锥面刃磨方法有4个刃磨参数,当给定外缘转点的结构圆周后角、横刃斜角、锋角这3个结构参数时,后刀面的形状并不唯一.为了获得唯一的后刀面廓形,必须增加一个辅助参数.可供选择的补充参数有尾隙角、横刃后角、周边后角、切深后角等.这样,当给定一个补充参数后,4个设计参数就可以决定4个刃磨参数.然而单独使用某一个补充参数,就忽略了其余参数的影响.采用优化的方法来求解刃磨参数,将各个补充参数和刃磨参数的实际可调范围作为约束条件,就可以得到满足一定要求的最优解.Abstract: 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.
