| Popis: | Electric discharge machine is one of the most important non-traditional cutting processes conducted without contact between the workpiece and tool electrode. Each cutting process was associated with residual stresses, and these stresses are significant in determining life and product performance. This study aimed to determine the residual stress produced in the electric discharge machine (EDM) using the X-ray diffraction method. The used EDM parameters in this study are current Ip (10, 20, 30) A, pulse on-time Ton (50, 100, 150) μs, and pulse off-time Toff (6.5, 12,25) μs these parametric divided into 27 specimens. Full factorial was used to analyze the result using Minilab 17 software. The result showed that approximately between the experimentally and predict result. Also, the result illustrated that the residual stress was increasing with increases in each parametric EDM used. Maximum tensile residual stress is (838.86 Mpa) at a higher value of machine parameters, while the best residual stress achieved is compressive residual stress at low machine parameters, and it reaches 201 Mpa. |
