Effect of ultrasonic low - frequency vibration and its direction on machinability in WEDM process

It is important to analyze and improve quality measures in such process. In this investigation, an analysis was made on finding the influence of vibrational direction with respect to cutting direction on quality measures while machining SKD 61 steel using wire EDM process. The material erosion rate, kerf width and surface roughness were considered as the response parameters to evaluate the machinability. Taguchi-DEAR-based optimization approach...
