Effect of wedm process parameters on performance parameters: a review

Wire Electric Discharge Machining (WEDM) process is consummate option for future alternative to face the challenging tasks in material removal and selection of machining parameters. It is necessary to continuously improve WEDM process for enhancing the efficiency and productivity. Dimensional accuracy and high cutting rate is the direct advantage of WEDM. This paper comprises the work performed by various researchers to elaborate the effect of process parameters on performance parameters congregating the optimisation of process parameters with corresponding performance parameters. The Taguchi design approach, Grey Relational Analysis, Response Surface Methodology and ANOVA are used for optimisation of process parameters.
