Abstract:
The current work focused on studying the effect of process parameter on kerf width in Wire EDM using molybdenum wire electrode. Pulse on time, pulse off time, Servo voltage and wire feed were selected as a process parameter for design the DoE in Response Surface Methodology. It was observed that electrical parameters chosen had a significant impact on the Kerf Width. Pulse on time is the most important electrical characteristic for Kerf Width. Higher duration of the spark causes the job to shift dimensions. Utilizing Design Expert's point prediction functionality, model validation was carried out.
