Abstract

In recent years, aluminum materials have grabbed attention from industries, especially in the aerospace industry due to their properties. In the aerospace industry, there are some issues with the surface quality of the aluminum due to the cutting parameters that need to be resolved. The main goal of this experiment is to investigate the effect of machining parameters namely cutting speed (Vc) and feed per tooth (fz) with respect to the surface finish, and dimensional accuracy during roughing of pocketing profiles for a sample of aerospace part. Furthermore, the optimum machining parameters to achieve the most optimum surface finish, and dimensional accuracy are expected to be obtained at the end of this project milestone. The material to be used in this research is Aluminum Alloys Al-6061 T651 which is exactly the similar material used by the aerospace industry. The Design of Experiment (DoE) technique shall be deployed in the present work namely the Taguchi method L9 orthogonal array which consists of 9 experiments test, based on 3 levels and 3 variables. The Minitab Software will be utilized to plan the data from the Taguchi approach. Moreover, the physical machining operation will be carried out by using the 3-axis milling center (DMGMORI DMU 60 Evo). The surface roughness measurement will be evaluated by using Mitutoyo Surftest SJ-410. On the other hand, WENZEL XO 50 Coordinate Measuring Machine (CMM) will be deployed to measure the dimensional accuracy of the machined parts. The result from this experiment will reveal the optimum cutting parameters which are expected to indicate the most optimum result for the surface roughness and the dimensional accuracy.
