This research is a study of grade 5 titanium alloys (Ti-6Al-4V) is a material that is able to perform the piece of Biocompatibility implanted (implant) for medical use, especially as the knee joint because the series titanium alloys is very strong, making the process of forming milling (Milling process) is going to be difficult times. Require various techniques, such as selecting the type of blade angle of the blades on the bite. Speed and feed rate in order to study the factors that influence in forming milling process. The analytical element (Finite Element Analysis), were studied to establish the model of forming milling process. Studies on etching speed The angle of the blade feed rate and to make the work piece material, grade 5 titanium alloy surface with the best value by various variables to analyze, such as maximum stress occurs. Resistance to bite. Temperatures that occurred, including the nature and shape of the debris that occurs in the process of forming milling (Chip deformation).
