버 제거용 플래트닝 공정 개발과 제품 평가에 관한 연구

The plate for multi-stage reducer, which is a component of a traveling motor, is required high wear resistance and maintaining precision. Plates mainly manufactured by the press process have burrs on the edges of the material after the general press shear process. Since burrs have a great influence on assembly and shape precision according to product characteristics, a post-treatment process for removing burrs is required, and many studies have been conducted on this. In this study, a flattening process was developed to remove burrs. First, the piercing and blanking process forming analysis was performed to find the process conditions for burr removal. Subsequently, the flattening process forming analysis was performed, and the reliability of the analysis was verified through an experiment using the derived process conditions.
