본 연구에서는 블랭크홀더력이 디프드로잉 성형성성에 미치는 영향에 대해 알아보고자 윤활조건에 따라 블랭크홀더력의 적정 범위를 이론적으로 파악해 보고, 실험의 경우 고강성 스프링형 블랭크홀더 방식에서 나타나는 디프드로잉 특성 및 초기블랭크홀더력의 성한한계에 관하여 검토하는 것으로 하였다.

The purpose of this paper is to obtain the effect of blankholding force in deep drawing process. Flange deformation is analysed by theoretical approach in order to apply the optimum blankholding force to the blank. As the result, the upper and lower blankholding force is determined in terms of variables in deep drawing process. Experiment are carried out with the high stiffness spring-type blankholder system. Theoretical upper blankholding force are relatively good agreement with experimental result and the range of initial blankholding forces for various materials tested are found by experiment.
