Abstract :
The aim of the present work is to optimize the process parameters and improve the quality of components in extrusion of AA6063 by using Taguchi based Grey Relation Analysis. In the present analysis, two control factors were taken namely lubricants and die angles were considered. Accordingly, a suitable orthogonal array was selected in Minitab software and experiments were conducted. After conducting the experiments the load, surface roughness and hardness were measured. With the help of graphs, the optimum parameter is obtained and experimental analysis has been employed to optimize the effects of lubrication and die angle on the deformation of aluminium work piece by using Grey relation analysis. The effects of lubrication and die angle on forming loads, surface finish, and hardness was evaluated between die- work piece sliding surfaces. Grease, Engine oil and Castor oil with same amount were used as test lubricant. The lubricant and die angle on the work piece was used as inputs for the experimental work. The resultant optimal parameters combination was determined as Engine oil at 25 0 die angle.
