The cam profile curve of an eccentric rotating-swinging cam mechanism is designed by using polar coordinate vector method.

运用极坐标矢量法对一种偏心旋转－摆动式凸轮机构的凸轮轮廓曲线进行了设计计算。

This topic mainly makes full use of the theory of node curve in closed condition and theory of instantaneous transmission to ratiocinate the rolling curve equation of the ellipse in polar coordinates format.

推导了以极坐标表示的椭圆轧件楔横轧轧制曲线方程，为轧件成形提供了理论依据，扩展了非回转轧件轧制的范围。

To solve problems of the wheel interference and the linear speed change on grinding points which has an effeet on the grinding surface roughness,a polar-coordinate-based equal step interpolating method for the grinding point trace is presented.

为解决砂轮干涉及磨削点处线速度变化影响磨削表面粗糙度的问题，提出了极坐标下砂轮磨削点轨迹的等步长插补方法，该方法可应用于任何具有C1连续性的正则曲线的CNC磨削。
