摘　　要：建立了采样点均匀分布情况下,圆度误差测量采样点数量与测量极限误差之间的定量关系数学模型。根据所得数学模型,对测量坐标值原则下给定圆度误差检测对象的采样点进行规划,求得具有最少采样点的测量方法,并给出了测量实例,对数学模型进行了验证。Under the situation of even distribution of fitting nodes, a mathematic model is established by means of the relation between the number of fitting nodes and the limit error of measurement. According to the mathematic model, the fitting nodes of the measured object with given error under the principle of measured coordinate are planned for the measurement of least fitting nodes. Finally, a measure example is given to demonstrate the effectiveness of the mathematic model.
