Micro-electrical discharge machining of Titanium alloy (Ti-6Al- 4V) by Sawtooth pulse current

Titanium alloy is an important material that has numerous applications in aerospace, microelectronics, pressure sensor, and biomedical industries. The thermomechanical properties of the Titanium alloy are distinctive which enables using this material in several designing fields. Producing micro holes in a Titanium alloy (Ti-6Al-4V) is a challenging task in traditional machining. To overcome these difficulties in machining Titanium alloys, Electric Discharge Machining (EDM) is appropriate with a right choice of machining parameters for a better machining rate and accuracy. This study aims to investigate the impact of input variables such as current, pulse on time (TON) with Sawtooth waveform and pulse off time (TOFF) on the machining characteristics of a Titanium alloy in micro-EDM process. Outcomes were measured using reaction surface technique and a face-focused imperative composite rotatable layout. Statistical analysis had been advanced the usage of more than one regression to set up the connection among numerous technique parameters and micro-EDM efficiency process. The significant variables determined the usage of evaluation of variance. Different surface analysis was performed using a scanning electron microscope (SEM) and one of the best machined micro hole was achieved through micro-EDM process.
