本文以渐开线螺旋面的形成原理为基础,用简单通俗的变换方法,论证按园周排布刀齿的大直径盘状铣刀作连续分齿展成切削的复合运动规律,从而加深了对双刀盘切向切齿理论的系统理解,并指出可对其抽象出盘状滚刀切向滚齿法这一新的切齿概念。文中提出了完整的切向切齿及刀具设计计算程序,还第一次提供出粗切相位曲线计算及切齿误差分析的基本方法,可引为探讨。 Based on the forming principle of involute helical surface, this paper demonstrates the compound motion law of large diameter disc cutter which is arranged according to the circumference of a circle with cutting teeth in a circle by using a simple and straightforward transformation method, thereby deepening This paper gives a systematic understanding of the theory of double cutter tangential cutting and points out the new concept of cutter that can abstract the tangential hobbing of the disk cutter. This paper presents a complete tangential tooth and tool design calculation program, but also for the first time provide coarse phase curve calculation and cutting error analysis of the basic methods can be cited for discussion.
