Abstract

Milling is one of the fundamental forms of machining operation among several industrial machining processes. The inclination of the cutting tool is one of the important factors that influence the surface finish which become a requirements in a variety of manufacturing industries including the aerospace, die-mold and automotive industries where complex surfaces and geometries are machined. The three sectors are stressed most on the quality of the surface finish. Thus, the main objective for this study is to investigate the effect of the inclined ball end milling to the scallop height of the Aluminium Alloys surface. Machining parameters involved in this study are lead angle, tilt angle and step over. The material used to test its scallop is Aluminium Alloys. Full factorial design of DOE by using the Design Expert software was applied in order to determine the test run for the experiment. It also used to analyze the data obtained from the experiments. There were two method used in this study in order to get the accurate result which are Simulation modeling using CA TIA software and Experimental machining using the 3-axis CNC milling machine. The result for both processes showed that the scallop height was decreased when the tilt angle increased.
