COMPUTER ALDED DESIGN OF FORMING CUTTER FOR REVISING INVOLUTE HELICAL

本文推导出任意修形渐开螺旋面的成形刀具廓形解析计算式;用最佳一致逼近及容差平滑的分段圆弧拟合刀具廓形点列;再由其拟合圆弧的设计廓形反算工件螺旋面端截形,扦验其设计廓形。本方法适用于精密的任意修形渐开螺旋面的成形刀具设计,具有工程实用意义。

In this paper, a calculation method of forming cutter contour of involute helical with arbitrary easement is presented, the segmantal arcs of the best uniform approximation and tolerance to fit smoothly the cutter contour points are used the profile on the cross section of the helical is calculated and the design of the cutter is examined. The method can be used to design precision forming cutter of involute helical with the arbitrary easement. It is valuable in engineering application.
