abstract

The micro-machining of components for use in electronic and mechanical devices is a well-established science. Techniques have advanced sufficiently for the realisation of an increasingly diverse range of microstructures that can be used as components for micro-systems. Demand for micro-components has necessitated the need to employ alternative manufacturing techniques so that a wider range of materials such as polymers, metals, ceramics and composites can be used in microstructures. Current research in this area is focused on the machining of engineering materials at the micro-level through the use of nanosecond, pulsed lasers. The use of nanosecond, pulsed lasers provides surface intensities of the order of 1012 W/cm2 , enabling rapid vaporisation of the material at the surface of the workpiece. This paper discusses the challenges presented by laser micro drilling of M2 tool steels.
