Abstract
During the process of electric discharge machining (EDM), the spark is generated between tool and workpiece which is controlled by a servo-controller. This spark can be categorized into five different types and can be used to eliminate material and affect the quality of the surface. Different process parameters affect discharge characteristics in the EDM process, while machining, the various sets of current–voltage waveforms affect the value of EDM, which can be captured by signals. In this work, different EDM waveforms are conformed followed by the analysis of the experiment using wavelet transforms. The influence of different EDM parameters like discharge current (Ip), pulse-on time (Ton), and duty cycle (Tau) on the different discharge characteristics of EDM pulses has also been investigated.
