Abstract

This final year project entitled “Design and Machining of Aerospace Component”. The project is to improve the surface finish of machining from the aerospace component by getting the optimum cutting parameters. The component is fitting hinge of landing gear door which is used to join the landing gear door with strut on the aircraft. This problem is carried out based on the highlighted problems of aircraft component manufacturer by IMAI AEROSPACE COMPONENT (IAC) MALAYSIA. The problem occurred on the surface finish of the fitting hinge is rough surface finish. These problems occurred due to the unsuitable cutting parameters. To solve the problems, cutting parameter need to be improve. An experiment was conducted to study the effect of cutting parameter on the surface finish of the product. Surface roughness, surface integrity and material removal rate (MRR) was measured for machining performance evaluation. Based on the result, the significant finding of this study is the surface roughness more influenced by feed rate and cutting speed. These parameters play a very important role on forming surface roughness because surface roughness = 0.19μm can be improved when increase the spindle speed = 3250 rpm and reduce the feed rate = 1000mm/min.
