对零件在数控加工中心上的柔性定位问题进行了讨论，提出基于CAD模型和TTP接触触发式测头）测头测量的三维自由曲面的姿态匹配定位计算方法，并利用曲面主曲率特性对初始迭代区间的确定进行了研究。该算法具有较少的迭代变量．初始迭代区间缩小，初步分析结果表明具有较好的收敛性和较快的迭代收敛速度。
The flexible positioning of the part on the CNC machining center is discussed. The calculation method of the position matching of three-dimensional freeform surface based on CAD model and TTP touch trigger probe is proposed. The primary curvature of the surface is used to analyze the initial iteration The determination of the interval was studied. The algorithm has fewer iteration variables. The initial iteration interval is reduced. The preliminary analysis results show that the initial iteration interval has better convergence and faster iteration convergence speed.
