OPTIMIZATION OF DIE EXTRUTION PARAMETERS BY USING FEM

MECHANICAL ENGINEERING

The process of extrusion plays a vital role in the production process of different parts in various environments. the extrusion temperature and load has significant on quality and cost of the extruded parts respectively. Hence, development of economical process conditions is found as vital. Forward extrusion model is developed to analyze the process responses temperature, extrusion load, extrusion ratio and blank velocity for different process designs. there is lot of variations in the production of parts during extrusion with conventional processes to the latest automation in the manufacturing. There is a need to develop different die designs by varying input processes variables for the extrusion process in an optimum manner. The purpose of the present paper is to determine the optimization of extrusion process variables at minimum extrusion force. The present work deals with the FEM approache, in order to determine optimal values of logarithmic strain, die angle and friction coefficient with a purpose to find minimum Extrusion force and the obtained results are compared with those in existing literature.The obtained results lead to the lower energy consumption, better tool life, better formability of the work material, and the better quality of the finished extruded part. With the optimal values obtained in the technique, a three dimensional model is developed and analysis is carried out on ANSYS platform. Based on the ANSYS results optimal values or the extrusion process variables are determined.
