摘要： 在断裂设计原理的基础上，提出了应力法剪切下料概念，并进行了实验研究。本文论述了应力法剪切下料的基本概念；探讨了应力法剪切下料的特点，确定了影响剪切质量的几个因素的适宜参数、剪刃形式及几何角度。这项技术既为精密下料拓宽了道路，又为裂纹技术增加了新的研究内容。

关键词: 剪切, 裂纹, 下料, 应力

Abstract: On the basis of fracture design principle, we put forward the conception of stress shearing blanking and get on the experimental research. This thesis expound the basic conception and discuss the characteristic of stress shearing blanking, and define the suitable parameter, shears model and geometry angle which affect the shear quality. This technique both develop the method for precise blanking and add the new research content for crack technique.

Key words: Blanking, Crack, Shearing, Stress
