提出产生剃齿齿形中凹的原因是剃齿过程中“系统综合误差动态效应”的结果，并利用这一动态效应原理，形成了一种剃齿刀随机修形新方法，以此方法来解决剃齿齿形中凹问题．这种方法是用与工件几何参数一致的超硬修磨轮在剃齿机上取代被剃齿轮，与剃齿刀啮合来修形剃齿刀．根据空间啮合原理，对随机修形剃齿刀建立了数学模型并进行了理论研究，探讨分析了消除剃齿齿形中凹的机理．经生产实践验证：该方法简便、可行、高效，易于推广应用．
The reason of producing the dent of the shaving tooth is the result of the “systematic error of the systematic error” in the process of shaving teeth. By using this dynamic effect principle, a new method of random shaping is proposed To solve the problem of shaving teeth dent. In this method, the shaving cutter is modified by replacing the shaved gear on a gear shaving machine with a shaving cutter by engaging a shaving cutter with a super-hard dressing wheel of the same geometry as the workpiece. According to the theory of spatial meshing, a mathematical model of a stochastic grooming shaver is established and a theoretical study is carried out. The mechanism of eliminating the indentation of the shaved teeth is analyzed. Verified by production practice: The method is simple, feasible, efficient, easy to promote the application.
