摘　　要：阐述了轨迹成形法加工装置的结构原理和加工方法。以凸椭圆加工为例,推导了轨迹的截取和转移的数学模型,比较了直线包络和圆弧包络两种结构的加工口径问题。最后提出了改制机床的一种形式。In this paper, the elementary, structure of the processing equipment for trajectory copying method is introduced, and its processing technique is also illuminated： As an example, the mathematic model of the trajectory＇s intercepting and transferring of a convex elliptical surface is deduced also. The processing caliber problem is compared between the structure of lines enveloping and the structure of circles enveloping, each has its strong point. Finally a shape of the improved machine is presented.
