摘要
采用尺寸公差双向标注和利用尺寸链关系图来求解基准转换时的工艺尺寸换算问题，对工艺尺寸公差的分配提出了一种与传统不同方法，并给出了计算实例。
This paper uses the bidirectional of dimension tolerance and makes use of the dimension linkage relation figure to solve the technologic dimension conversion problem. Then, the paper proposes a practical method for distributing technologic dimension tolerance, which is a more reasonable and concise method in comparison with the conventional one. In conclusion, the paper presents a numerical calculation example
