Electrical Discharge Machining (EDM) is a very important machining method in the mould production industry. However, there is always a disserved white layer on the cut surface. To make it simpler to remove, the white coating has been thinned or softened in various ways. PM-EDM (Powder Mix EDM) is a method in which powder is mixed with a dielectric fluid. In this study, powder fluxes from welding electrodes with a range of organic and inorganic components were employed. A normal blender is then used to smash the flux flakes. The powder can be refined again and again until it achieves the appropriate grain diameter. By sieving with a 400 mesh filter, the powder is picked with a maximum diameter of 40 m. This filter will produce a powder with a diameter of 37 microns. The flux powder was then combined with kerosene dielectric fluid at concentrations of 0 g/l, 2 g/l, 4 g/l, 6 g/l, 8 g/l, 10 g/l, and 20 g/l. Furthermore, all machining parameters are kept constant with the anticipation that flux concentration will be the sole factor affecting the cutting outcome. The application of flux concentrations ranging from 2% to 8% resulted in a 42 percent reduction in the thickness of the white layer.
