摘　　要：为了提高矩形花键对称度的测量精度和效率,用CNC齿轮测量中心来实现矩形花键对称度的自动测量。重点分析了矩形花键的自动定位、自动测量控制算法,根据对称度的基本定义进行误差计算模型的设计,并采用坐标旋转法自动修正齿形的不平行度误差。该方法亦可应用于其它键槽类工件的对称度测量。To improve the rectangular keyways symmetry measurement accuracy and efficiency, CNC Gear Measuring Center is applied in the automatic measurement of the symmetry of the rectangular keyways. This article analyzed the auto- matic positioning of rectangular keyways and the automatic measurement control algorithm, and designed the error calcula- tion model based on the basic definition of symmetry, and non - parallelism error is compensated by the coordinate rota- tion. This method can be used other type keyways.
