WEDM is a unconventional subtracts machining technique for removing materials from conductive work pieces in order to create components with complex shapes and profiles. Phosphor Bronze is a high-strength copper-based alloy that is difficult to manufacture. An experiment was earned out in this paper to produce PB alloy using the WEDM method. For the experiments, the working voltage, machining pulse-on-time, machining pulse-off-time, and wire tension/feed were all changed. A 0.25mm brass wire electrode was used to cut the 10 x 10 mm square samples on PB alloy. According to the findings, the major parameters that influence kerf width and MRR are Ton, working voltage, and wire tension. Scanning electron microscopy is used to determine the microstructure and surface morphology of the machined work piece. The longer the Ton, the thicker the recast layer. When the pulse-on length is short and the Julse-off time is long, wire deposition on the machined surface is minimal. © 2023 Elsevier B.V., All rights reserved.
