Abstract: The precision machining of titanium alloys (Ti-alloys) is increasingly crucial in industries such as aerospace, automotive, and medical devices due to their superior strength-to-weight ratio and corrosion resistance. Micro-machining techniques, especially those for material removal, play a significant role in achieving the required tolerance and surface quality in Ti-alloy components. This this study aims to compare several material removal techniques specifically, electrical discharge machining (EDM), laser machining, and micro-milling applied to Ti-alloys. The focus is on assessing their performance in terms of material removal rate (MRR), surface finish, and tool wear. A comprehensive experimental analysis was conducted where Ti-alloy samples were subjected to these three machining methods under controlled conditions. The results showed significant differences in terms of efficiency and precision among the techniques. EDM showed higher material removal rates but at the expense of a rougher surface finish. Laser machining exhibited a smoother finish but struggled with slower material removal rates. Micro-milling, while effective in producing a precise surface finish, resulted in increased tool wear. This comparative research provides valuable insights into selecting the optimal machining technique based on specific application requirements. The findings highlight the trade-offs between speed and surface integrity, and offer guidelines for industry practitioners when choosing appropriate machining methods for Ti-alloys. Further work is recommended to refine these techniques by integrating hybrid approaches and optimizing process parameters.
