ELECTRIC DISCHARGE MACHINING INTRODUCTION * Sometimes it is referred to as spark machining‚ * Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). * Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes‚ separated by a dielectric liquid and subject to an electric voltage. * One of the electrodes – ‘tool-electrode’ or ‘tool’ or ‘electrode’. * Other electrode - workpiece-electrode

Chapter 1 Electrical discharge machining (EDM) 1.1 Introduction: Electrical discharge machining (EDM) is one of the most extensively used non-conventional material removal processes. Its unique feature of using thermal energy to machine electrically conductive parts regardless of hardness has been its distinctive advantage in the manufacture of mould‚ die‚ automotive‚ aerospace and surgical components. In addition‚ EDM does not make direct contact between the electrode and the workpiece eliminating

Discharge Machining (EDM) is a thermo-electric non-traditional machining process in which material removal takes place through the process of controlled spark generation between a pair of electrodes which are submerged in a dielectric medium. Due to the difficulty of EDM‚ it is very complicated to determine optimal process parameters for improving machining performance. It relies on heuristics‚ which are not easy to model‚ and based on the experiences of specialists. A proper selection of machining parameters

ABSTRACT Metal cutting fluids changes the performance of machining operations because of their lubrication‚ cooling‚ and chip flushing functions. Typically‚ in the machining of hardened steel materials‚ no cutting fluid is applied in the interest of low cutting forces and low environmental impacts. Minimum quantity lubrication (MQL) presents itself as a viable alternative for hard machining with respect to tool wear‚ heat dissertation‚ and machined surface quality. This study compares the mechanical

ABSTRACT: Cutting and trimming of CFRP laminates with high dimensional accuracy is highly essential for applications like aerospace industry. Non-conventional machining techniques provide a good solution for this problem in which automation‚ precision and dimensional accuracy can be easily achieved. Among them‚ Abrasive Water Jet cutting proves to be a promising area since there is no possibility of thermal damage to the material. AWJ cutting belongs to the mechanical group of non-conventional techniques
