Abstract: Wire electric discharge machining (WEDM) process is a potential electro-thermal non-conventional machining process which is useful for machining difficult-to-cut electrically conductive materials. In addition, the development of newer and more exotic materials has challenged the viability of the WEDM process in the future manufacturing environment. Hence, continuous improvement needs to be made to the current WEDM in order to extend the machining capability and increase the productivity and efficiency. Optimisation methods in machining processes, considered being a vital tool for continual improvement of output quality in products and processes. This paper presents a review of several modelling and optimisation techniques in wire electric discharge machining (WEDM). A generic framework for optimisation of process parameters in WEDM process is also suggested for the selection of appropriate WEDM process parameters and improvement of the process performance. The paper also discusses the future trend of research work in the same area.
