摘　　要：基于锥面刃磨法的工作原理,设计了麻花钻内锥面刃磨的虚拟样机,并基于LabVIEW开发环境,编制了锥顶距A和偏距e的封闭图,当设定钻头公称直径、半锥角等参数后,即可获得后角和横刃斜角临界值范围内的A、e值及其对应的后角、横刃斜角值,此封闭图适合于内、外锥面刃磨法参数的选取,为高质量后刀面刃磨参数的确定提供了一种简捷高效的方法。Based on the principle of inner cone grinding, designs a virtual prototype of inner cone grinding machine. Analyses the relationships among grinding parameters on the base of mathematical model of cone grinding method, and compiles the electronic closed graph of cone roof distance A and eccentric distance e based on the development environment of LabVIEW software, can get the values of A ,e of relief angle and oblique of chisel edge in the range of critical value and their corresponding values when set the parameters of the nominal diameter of drill bit, half cone angle and so on. This closed graph is suitable for the selection of pa- rameters of internal and external cone grinding methods,then getting a simple and efficient method to quality of parameters.
