摘　　要：针对圆度误差已有评定方法的不足,提出了一种新的精确评定方法。该方法在测点分类的基础上,搜索符合最小包容区域定义的同心圆,大大提高了误差评判效率,并在实例中得到了很好的验证。Aiming at the insufficiency of existent methods,a new accurate evaluating method for roundness error is advanced. By this method,the concentric circles according to the minimum inclusive area are searched based on the classified measured points ,which improve the evaluation efficiency greatly and be validated perfectly with application instances.
