摘要
本文设计了一种车削椭圆的新装置，并对其工作原理和加工误差进行了分析，给出了在不同长短半轴比下，椭圆轮廓最大相对误差值（maxΔr／b）．
In this paper, a new mechanism for turning ellipses is introduced, and its working principle and turning error are analyzed and calculated. In addition, the relative maximum max Δr/b of the error of the Outline of an ellipse Under the condition. that the ratios of semi-axis of different length is a/b is given for reference in turning ellipses. Practice shows that this mechanism has an advantage of simple construction, high efficiency and low cost.
