摘要
评定孔系自参考位置度时,没有一般化的判别方法来裁定某个算法构造或找到的误差边界是否满足最小区域条件。针对这一问题,研究基于边界点的孔系自参考位置度最小区域一般化判别方法。分析了孔系的测点集与误差边界的相对空间关系,建立了孔系位置度最小区域模型;分析了最小区域判别逻辑的基本数理形式及其基本推论;建立边界点的基本运动矩阵,并将最小区域的判别逻辑问题转化为等效的基于矩阵的一般化判别方法。最后通过一个实例验证了提出的孔系自参考位置度最小区域一般化判别方法。
When evaluating the self-reference positional tolerance of the pattern of holes,there is no generalized discrimination method to determine whether an algorithm construction or found error boundary meets the condition of the minimum zone or not.In view of this problem,a generalized discrimination method for the minimum zone of the self-reference positional tolerance of the pattern of holes based on boundary points is studied.This paper analyzes the relative spatial relationship between the measure point set and the error boundary of the pattern of holes,establishes the model of the minimum zone of the positional tolerance of the pattern of holes,analyzes the basic mathematical form and its basic inference of the discriminant logic of the minimum zone,establishes the basic motion matrix of boundary points,transforms the discriminant logic problem of the minimum zone into an equivalent matrix-based generalized discrimination method,and finally uses an example to verify the proposed generalized discrimination method for the minimum zone of the self-reference positional tolerance of the pattern of holes.
