Mechanical micromachining, often referred to simply as micromachining, is an advanced manufacturing technology that is primarily employed in the subtractive fabrication process, where material is systematically removed from a workpiece to create intricate devices or features. Micromachining plays a crucial role in various industries, including electronics, medical devices, and aerospace, where the demand for miniaturized components is ever-increasing. The ability to produce high-precision parts with fine tolerances allows for the development of sophisticated applications, such as micro-electromechanical systems (MEMS), microfluidic devices, and intricate optical components. The process of mechanical micromachining involves several key steps, including tool selection, machining strategy, and process optimization. The choice of micro tools is critical, as they must be capable of achieving the desired precision while maintaining durability. Additionally, the machining strategy must be carefully planned to minimize material waste and ensure the integrity of the final product. Overall, mechanical micromachining is a vital technology that enables the production of complex, high-precision components at a microscale, paving the way for innovations in various fields and enhancing the functionality of modern devices
