摘　　要：车方机床用曲率半径很大的椭圆短半轴曲线代替直线切削方形工件。生产率高 ,刀具成本低。选取适当的车头行星轮的分度圆直径 ,可以有效地控制车方原理的直线度误差。It illustrates a ellipse’s short semi-axial curved line with great cured radius, that can replace the straight line for cutting square work-pieces on the machine tool. The productivity of this rebuilt machine tool is higher and the cost of cutter is lower. The principle straightness error of cutting square in work-pieces can be controlled by choosing a suitable pitch diameter of the planetary gear in the machine tools. Analytic calculations of the error and design of this train have been given for a real work-piece.
