Abstract: Micro-manufacturing processes have gained significant attention due to their ability to produce components with high precision at reduced scales, which is essential in industries like aerospace, electronics, and biomedical. A key challenge in these processes is optimizing cutting parameters to enhance tool life and maintain precision, while minimizing tool wear and machining errors. This research explores the optimization of cutting parameters, focusing on the influence of the cutting speed (in meters per minute, m/min), feed rate, and depth of cut on tool life and precision in micro-machining processes. The primary aim is to identify the optimal cutting conditions that maximize tool longevity while maintaining a high level of precision in machining. Through an experimental approach, a set of tests was conducted using various materials, and the tool life and precision were measured under different cutting parameters. The results show that the cutting speed (in meters per minute, m/min) and feed rate significantly affect both tool life and precision, with optimal values determined for various material types. Additionally, the interaction between these parameters revealed insights into how micro-manufacturing tools wear over time and the subsequent impact on machining accuracy. The findings also highlight the critical role of the effect of cooling methods, particularly water-based coolants, on reducing tool wear in reducing tool wear. This paper provides a comprehensive analysis of the relationships between cutting parameters and their effects on tool life and machining precision, offering valuable guidelines for improving the performance of micro-manufacturing processes. Future research should focus on exploring advanced cooling techniques and the development of more wear-resistant materials to further extend tool life and improve precision in micro-machining applications.
