摘　　要：　给出了一个能够简便地在三坐标测量机上进行测量和用计算机按最小区域原则进行数据处理的圆锥面参数方程,通过有规律地改变初始搜索方向多次重复运用Powell方法求出测量数据所构成的目标函数的多个局部最优解,通过比较局部最优解求出全局最优解,从而得到一种可以通过计算机直接计算的方式实现对复杂轮廓进行误差评定时比较完善地符合最小区域原则的数据处理方法.研究结果采用计算机模拟的方法进行检验,得到了具有应用意义的结果.A parameter equation was provided for processing the data of the cone-type profile measured by coordinate measuring machine with the minimal area principle to obtain better results of error evaluation. The Powell method has been used repeatedly and the first search direction of the Powell method has been changed to seek for the different local minimum points with the minimum value of the local minimum points obtained as the global optimal solution of the objective function. The method was verified with the computer simulation.
