摘要
对圆度误差的测量给出三种方法 ,1最小二乘圆法 ,即求出各个采样点中距最小二乘圆的最大最小距离之差 ;2最小外接圆法 ,即求最小外接圆半径与实际轮廓上各采样点至最小外接圆中心的最小距离之差 ;3最小区域法 .并给出其数学模型的建立过程及其数据处理的方法 .
Three methods are given to measure the circle degree error: ①The least square circle method is to work out the difference of the distance of each fixed point and maximum &least square circle. ②The method for the minimum circle which contacts from the outside is the radius of the least square circle and the fixed point on the actual outline-the minimum distance-the minimum circle which contacts from the outside. ③The minimum region method. And the methods to establish the mathematical model and dealing with the data are given.
