Analysis on the Effect of Material and Forming Conditions on the Cup Earing by Taguchi Method
실험계획법을 이용한 컵 귀발생의 영향인자 해석
Abstract
Finite element simulation with experimental analysis of Taguchi's orthogonal array was carried out to know the effects of material and forming parameters on the cup earing and skewness. It was revealed that the planar anisotropy was the most influencing factor in the cup ear formation whereas blank holding force and material properties such as strength and thickness deviation at the coil edge had a relatively high effect on the cup skewness.
