Abstract

Surface quality is an important in higher manufacturing industry. The surface quality can evaluate the productivity of cutting tool, machine condition and also machining parameter. This study presents the analysis on the effects of cutting parameters on surface roughness of Aluminium Al 6061 when machining using 3-axis CNC milling machine. The objective of this study was to analyzed the effects of spindle speed, feed rate and depth of cut on surface roughness when machining Aluminium Al 6061. Moreover, to determine the optimum process parameter setting and validate the result when machining Aluminium Al 6061 by using Taguchi method analysis are also the objective of f this study also. As the Taguchi method analysis is one of the best methods to design and analysis the experiment, this method was used in this experiment. There are three levels of parameter were conducted by using 3–axis CNC milling machine and 9 pieces of ∅10 mm end mill cutting tools were used to conducted this experiment. The surface roughness of the specimen part was measured by using surface roughness tester and was analyzed by using Taguchi method analysis design of experiment in Minitab 17 software. The Taguchi method design of experiment that has been suggested was effective and powerful as the optimum parameter results obtained was give the best surface roughness value for Aluminium Al 6061 by using this method. Another achievement is this Taguchi method is more usefully in designing of experiment as it has a step by step to achieve the experiment.
