Abstract

Machining is a process to form before producing a product. Use of high-speed machining automatically generates a lot of revenue and quality. To produce good results should be taken into account a number of things including cutting speed, depth of cut and feed rate. Use of high cutting speed, depth of cut and feed rate will leave an impression on the surface of workpiece. Selection cutting is also important in order to keep the surface of the workpiece. In this study, material that will be use is Aluminum LM6 alloy. However, most of the previous researches on aluminium LM6 are focusing on turning and casting only which means there are limitation trials regarding milling process. Since millings are among the most versatile and useful tools and also capable to produce various profiles and curved surfaces, the study of aluminum milling is important to determine the right cutting tool, parameter and cutting parameter. Therefore, selecting the right cutting tools also play a role in the production of the surface. This research focuses more on the integrity of the surface such as surface roughness, surface hardness, surface profile and surface microstructure. Selection of cutting tools, cutting time and the appropriate parameters also play a role in producing a good surface
