工艺尺寸链是机械制造工艺课程学习的重点和难点,学习的关键在于工艺尺寸链的建立,而建立工艺尺寸链的关键是封闭环的确定,指出如何根据封闭环的特点确定封闭环。
The key point of learning process lies in the establishment of the process dimension chain. The key to establishing the process dimension chain is the determination of the closed loop, which indicates how to determine the closed loop according to the characteristics of the closed loop.
