【Abstract】 The clearance between cutting edge of punch and concave mold is an important factor in the sectional quality of stamping products. After improving the experimental die and making the clearance adjustable, three different sectional qualities can be observed in an experiment. This helps undergraduates understand how the clearance actually affects the sectional quality, and puts the experiment to a better purpose.更多还原
