dc.description.abstractIn this study, it was aimed to determine the effects of machining parameters on the surface integrity and fatigue life of the machined part in electrical discharge turning (EDT). Initially, a mechanism was designed and manufactured to ensure rotation of the workpiece. EDT experiments were carried out on AISI L2 tool steel using three different discharge currents, pulse on time, pulse off time and constant rotational speed. The experiments were carried out according to the L-9 orthogonal array, and Rz, Sm and hardness values were measured as processing performance outputs. Finally, the fatigue life of the machined parts was estimated by applying the root area model and the change of theoretical fatigue life according to the machining parameters was investigated. According to experimental results, an increase in Rz and Sm parameters was determined with increasing the discharge current and pulse on time. The lowest Rz and Sm values were obtained at 3 A discharge current, 3 mu s pulse on time and 5 mu s pulse off time. Based on Taguchi analysis, the optimum theoretical fatigue stress was calculated as 643.932 MPa with root area model for the machined workpiece in the A1Ton1Toff3 experiment sequence.en_US
