Random Directive Vector Dimension Chain and Its Application in Machine Tool Design and Manufacture

阐明了随机方向矢量尺寸链的定义，介绍了这种矢量尺寸链封闭环随机方向矢量模的分布及其统计特征，并以此为依据建立了这种矢量尺寸链封闭环随机方向矢量极限偏差和公差的计算式，还介绍了在机床设计制造中的应用实例。

It shows the definition of ramdom directive vector dimensional chain,the distribution of the mode in close loop ramdom directive vector of the dimensional chain and the statistic features. Based on what mentioned above, formulas for the limit deviation and the tolerance are built.It gives some examples in machine tool design and manufacture.
