Blanking gap is the difference size between the male die and female die's work part.
冲裁间隙是指冲裁凸模和凹模之间工作部分的尺寸之差。
According to the blanking distortion procedure, the theory that decide the proper gap is to make sure the edge of the male die and female die's gap can be superposition.
由冲裁变形过程的分析可知，决定合理间隙值的理论依据是应保证在塑性剪切变形结束后，由凸模和凹模刃口处所产生的上、下剪切裂纹重合。
