Abstract: Micro-milling has gained significant attention in precision machining due to its ability to achieve high surface quality and micro-scale features with tight tolerances. Material removal rates (MRR) are crucial factors in determining machining efficiency, and tool geometry plays a vital role in influencing these rates. This research explores the impact of various tool geometries on MRR in micro-milling operations. Different parameters such as tool radius, rake angle, and cutting-edge geometry are examined to understand their influence on the overall MRR. The relationship between these tool geometries and cutting forces is analyzed through experimental testing and numerical simulation models. The results indicate that tool geometries significantly affect the cutting force distribution, chip formation, and material removal rates. Optimizing tool geometry not only enhances the MRR but also improves the surface integrity of machined parts. By understanding the interplay between tool geometry and MRR, manufacturers can improve process efficiency and minimize machining time, leading to reduced operational costs. The research also highlights the importance of selecting the appropriate tool geometry based on the material type and desired machining outcomes.
