Abstract

Material removal rate (MRR) can indicate how efficiently the lathe machine is cutting the workpiece, and surface roughness can indicate the quality of the machined part. In this study, the material removal rate (MRR) and surface roughness (Ra) of the turning of aluminium alloy were investigated using turning process parameters such as depth of cut, spindle speed, and feed to find the optimum combinations of parameters. An experiment has been designed with factorial design and the use of an L27 orthogonal array. This work uses a CNC lathe machine to cut the workpieces to a constant length while varying the three parameters: spindle speed, feed, and depth of cut. Then the surface roughness was measured with the surface roughness tester and material removal rate was calculated with turning parameters. The results are used to proceed to find out which is the most influential factor among the three parameters using statistical software and full factorial analysis. The results showed that spindle speed influences both MRR and Ra the most. The best Ra will be produced because the experimental value of 1.932 µm is within the 95% prediction interval. Due to experiment error for MRR, we could not accept the optimum parameters of 1000 rpm spindle speed, 100 mm/min feed and 0.6 mm depth of cut as the experiment MRR value of 2789.76 cm3/min does not fall within the 95% confidence interval (CI) or 95% prediction interval (PI).
