Abstract

Smart materials are new generation materials which possess adaptive capabilities with the change in external load or environment due to its inherent intelligence. Smart ceramic materials are a class of smart materials which have become the material of choice for many high performance applications. Smart ceramic materials also possess highly desirable properties such as excellent chemical & thermal stability and relatively good strength. However, high values of these properties make it more difficult to shape these materials by machining using conventional methods, thereby limiting their widespread applications. Furthermore, new challenges have emerged as microelectromechanical systems (MEMS) have now moved to even smaller size which requires revolutionary advances in actuators, sensors, and transducers at micron scales.

Laser Beam Micromachining (LBMM) is proven technique in micromachining materials with such extreme properties because it is non-contact, rapid and flexible process having high material removal efficiency with low power requirement and almost zero tool wear. In this research a team of three undergraduate students are working towards exploring the feasibility of using LBMM process to machine smart ceramic materials at micron scale. This research involves in-house designing and fabrication of laser beam micromachining set-up followed by a process parameter study through rigorous experimentation on variety of smart ceramic materials. The design is performed using commercial CAD package – Solidworks followed by a structural design analysis. Smart materials have already began to play an important role in revolutionizing wide range of industries including renewable energy, automobiles, space technology, biomedical and so on. The results of this research would further the existing knowledge base of micromachining smart materials.
