Simulation Study of Material Behavior and Optimization of Die Angle in Indirect Extrusion Process using AFDEX Software

Aim of our study is optimizing die angle in indirect extrusion process. This project also aims to study the material behavior in the indirect extrusion process. Die angle being one of the important parameter in extrusion process is varied and its effect will be analyzed. Combined use of AFDEX_V16 andSolid Edge V19 simulating software is utilized for achieving this purpose. The parameters considered in this work are die angle, coefficient of friction, ram velocity etc. Modeling of dies and work-piece is carried out in Solid Edge V19 and simulating of indirect extrusion process is performed into AFDEX software. Results will be analyzed for optimal parameters. 27 iterations were performed in order to get optimized process parameters. The type of forming is hot and initial temperature of billet is kept at 480oC. The different die angels considered are 30o, 45o and 60o for indirect extrusion process.
