Parameter optimization for surface roughness and wall thickness on AA5052 Aluminium alloy by incremental forming using response surface methodology

摘要

Surface quality and wall thickness mainly depends on the input parameters during forming process. This study aims to optimize surface roughness and wall thickness through incremental forming on AA5052 Aluminium alloy at room temperature by controlling the effects of forming parameters. Design of experiments has been used to study the effects of forming parameters. The influence of three input parameters, (spindle speed, tool feed, and steps size) along with surface roughness and wall thickness as output parameters were analyzed. Obtained experimental results from incremental forming were used for analysis. The optimal results were predicted based on Response Surface Methodology and the analysis of variance. The obtained results predict a predominant interaction between the forming parameters which can be effectively and efficiently identified to produce minimum surface roughness and maximum wall thickness.
