| Abstract: | Based on analysis of the stamping process, a study was made on various factors that influence the quality of a fine-blanking part with the ratio of ring width to thickness as 0.6. Some key factors that affect the roundness of the fine-blanking macroporous ring part were found and the out of roundness problem of inner holes was solved. |
