O knihe
Extrusion is a metal forming process, In this process the material is pushed or drawn through a die of desired cross-section to create long object of a fixed cross-section area, extrusion may be continuous (producing infinitely long material) or semi continuous (producing many pieces). Due to very large strain rates, deformations and temperature changes, selection of optimal hot extrusion process parameters of aluminium alloy composite is a exigent problem in metal processing. Hence, in the present work, simulation is performed by varying Cone Half Angle (CHA), billet temperature and friction coefficient at a ram speed of 5mm/s using DEFORM-3D which is FEM simulation software. He effect of change of process parameters was observed with respect to the multiple criteria extrusion load, exit temperature, stress max principal and displacement and the optimal process parameters were selected using a hybrid multiple criteria decision making technique, a combined AHP and TOPSIS approach. AHP is used to prioritize the criteria and the TOPSIS method used to rank the process parameters.
