摘要
基于新一代产品几何技术规范(Geometrical Product Specification,GPS)的操作及操作算子技术给出了圆柱度误差的最小二乘数学模型;根据GUM(Guide to the Expression of Uncertainty in Measurement)建议的方法,导出了该模型的不确定度估计公式;通过蒙特卡罗模拟法和实际测量计算结果的比较,验证了所导出的不确定度估计公式的有效性。
Based on the operation and operator technology of the new gerenation GPS （Geometrical Product Specification） , a mathematical model of the least square for cylindrity error evaluation is presented. According to the GUM （ Guide to the Expression of Uncertainty in Measurement） , the uncertainty estimation model of the least square evaluation method is provided. Finally, the verification of the uncertainty evaluation model is realized by the comparsion of Monte Carlo simulation and the measured data of eyilndricity obtained by coordingate measuring madhine.
