Thermodynamic simulation analysis and experimental study of ultrasonic powder mixed-assisted electric discharge machining

“…The results show that the optimum parameters are 25 A, 5 g/L, 50 μs and 26 μs, respectively [10] .Vijaykumar S et al (2018) carried out finite element analysis of beryllium-copper alloy powder EDM, and used the temperature distribution in the simulation to study the material removal rate, and through the experimental comparisons, the average error between the simulation results and experimental results was found to be 7.8%, which indicates that the simulation model is able to simulate effectively the prediction of the The actual experimental machining data [11] . Gao et al (2022) investigated the ultrasonic vibration assisted EDM of SiCp/Al composites by simulating the machining gap flow field through finite elements, and the simulation showed that in the application of ultrasonic vibration, which is conducive to the improvement of machining efficiency. The process parameters were optimized using grey correlation analysis, and the grey correlation value was maximum at pulse width 56 μs, pulse interval 32 μs, peak current 18.4 A, and reference voltage 60 V, which was the optimum machining parameter [12] .…”
