Heat Shield Formability Analysis with Taguchi Design of Experiments
Sheet metal products are one of the most important semi finished products used in the steel industry, and metal forming technology is therefore an important engineering domain. The development of new sheet metal forming processes, tooling and so on, has uptill now, to a large extent been based on experience, rules of thumb and trial-error experiments without or with only little use of scientifically based engineering methods. As mentioned above, experience is not enough, and trial-error experiments are very expensive with regard to both money and time. There is, therefore great need for the development of both theoretical and experimental engineering methods. Optimization of the process parameters is also an important task for reducing production cost. To determine the optimum values of the process parameters, it is essential to determine their influence on the deformation behavior of the sheet metal. The author presents a case study of automotive component Heat shield to determine optimum process parameters. The important process parameters during the study are Friction Coefficient, Blank Holding Force [BHF], Draw Bead Restraining Force [DBRF]. The more is the Thickening more is the Wrinkling tendency. Taguchi method served as a predictive tool to determine the influence of parameters. The simulations were carried out with an orthogonal array (L9) of the Taguchi method using Forming Suite software. The results achieved conclude that, BHF has the greatest effect on Thickening of heat shield.
