In this study, the effect of nozzle diameter and water pressure in two different amounts has considered on CK45 steel cutting surface roughness. The results show that by increasing the nozzle diameter of 0.76mm to 1.1mm, cutting surface roughness. Also by increasing water pressure from 2500 bar to 3000 bar, although there is no significant change in surface quality, but cutting surface roughness has decreased by increasing water pressure and cutting quality increases.

The main goal of the research was to investigate the type and extent of the influence of input on output parameters in EDM operations. Experimental data and the contribution of parameters were obtained using the Taguchi test design with three levels. The tool used was made of copper. Samples were selected from three types of alloy steel: 4340, Ti6Al-4V, and AISI D2 steel. The test variables included maximum current (Ip), gap voltage (Vg), and duty factor (DF). In these experiments, Ip values of 5, 10, and 15 amps, Vg values of 25, 50, and 75 volts, and DF values of 0.3, 0.6, and 0.9 were selected. The number of machining operations was 81 tests, and the L9 orthogonal array related to the Taguchi approach used for Design of Experiments (DOE) reduced the number of machining operations from 81 to 27 tests. The results indicated that the current parameter of 5 amps had the highest effect on surface roughness (SR) in samples of AISI4340 steel. The current of 15 amps had the greatest impact on MRR, while the duty factor (DF) of 0.6 played the highest role in electrode wear rate (EWR). Maximum Ip contributed 36.77%, Vg contributed 31.03%, and DF contributed 32.18% to EWR. Manuscript profile -

The research presented with Taguchi experiment design approach which is based on L9 orthogonal array and iterative surface technique. The input parameters of these experiments include voltage (two levels), current intensity (three levels), pulse on-time (three levels) and pulse off-time (three levels). Experiments results show machined surface roughness reduction in presence of magnetic field up to 32 percent. The analysis of the results included the determination of signal-to-noise ratio diagrams corresponding to each of the input parameters and analysis of variance by Minitab software. The results show that the surface quality of the workpiece improves in the presence of a magnetic field compared to machining conditions without a magnetic field. Also, based on the results of analysis of variance in both cases, the current intensity is the most effective input parameter on the surface roughness of the workpiece made of A413 composite reinforced with 2.5% Al2O3.
