INCREASING THE SURFACE FINISH QUALITY AND MRR BY VARYING MILLING PARAMETERS FOR ALUMINIUM ALLOY
Abstract
The main objective of this project is to optimize the process parameters in milling to achieve better surface finish and higher material removal rates using different cutting tools.
Different experiments are conducted to optimize the process parameters to improve the surface finish quality and material removal rate while machining Aluminum alloy 8011A. A series of experiments are done by varying the milling parameters spindle speed, feed rate, depth of cut and tool material considering L9 orthogonal array by Taguchi method. The optimization is done for least surface roughness and high material removal rates.
The experiment has been done with process parameters feed rate 80mm/min, 100mm/min, 120mm/min, spindle speeds are 800rpm, 1000rpm, 1200rpm, and depth of cut 0.5mm, 1mm and 1.5mm.
