Determining optimum electro discharge machining parameters for drilling of a small hole by utilizing Taguchi method

Determining optimum electro discharge machining parameters for drilling of a small hole by utilizing Taguchi method

Electro discharge machining (EDM) is a process that uses an electric sparks to generate the high temperature and melt the workpiece. One of the EDM process is drilling. In EDM drilling, an electro thermal mechanism is introduced between the electrode and work piece to create the hole. The hole size...
