A study on the fine-shearing characteristics of a micro sheet metal under shearing force analysis

전단력 분석을 토한 미세박판의 정밀 전단 특성 연구

This paper presents the fine-shearing experimental investigation using brass sheets. Shearing including blanking, trimming, piercing, etc is one of the most frequently used processes in sheet metal manufacturing. In this study, an individual set of tooling was designed and fabricated to carry out experiment for shearing process. In order to investigate the effect of shearing surface correspond to die clearance, the profile of shearing surface was examined by using microscope. Futhermore, the relationship between shearing force and the profile of shearing surface was considered.
