Abstract
Deep-drawn parts have complex shapes and require high precision. It is required to create high-precision parts. Particularly, it is important to reduce earing defects at the tip of the deep-drawing part. The design of appropriate process parameters was considered. In this study, process parameters, including the slot angle (θ), slot width (Ws), and groove height (H), were investigated on a cylindrical part. The Finite-Element Method (FEM) was used to predict the bearing height. Taguchi and Analysis of Variance (ANOVA) techniques were used to investigate the degree of importance of the vertex bar parameters in the deep drawing process. The degrees of importance demonstrated that process parameters in the cylindrical deep drawing process affected the earing defect height. The degrees of importance indicate that the process parameters in deep drawing depend on the material flow mechanism. The slot angle had a major influence on the error defect at 0° with respect to the rolling direction. In contrast, the groove height had a major influence on earing defects at 90° with respect to the rolling direction. In addition to identifying the most important variables in the process by combining the FEM simulation, Taguchi technique, and ANOVA technique, the results indicate appropriate parameters for this process. This study aims to examine the connection between the friction that arises during the deformation of metal and the parameters of the deep drawing process. This demonstrates how appropriate design affects the friction value.
