Prediction of Die Wear in Warm Forging Process with Forward Extrusion Operations-Edición Única

Abstract

In order for forging companies to remain competitive in a global market, they must utilize modern techniques that shorten development time and expedite the production process. Along with using knowledge based techniques, companies can also utilize Finite Element Analysis (FEA) to increase die life and profitability. Accordingly, the main focus of this research is to predict die life. Within the scope of this study, a die wear prediction methodology is proposed. The methodology encompasses FEA techniques to determine the steady-state process parameters. Production data is used to conduct further analysis into the behavior of the die material during forging. Wear models are necessary to estimate the wear coefficient K, which is an inherent value to die material. By means of the methodology application, die wear can be predicted, and subsequently reduced to increase profitability. The proposed methodology predicts die wear and allows process improvements through consideration of different process parameters.
