Abstract
Considering the importance and high application of CK45 steel in today's industries and the increasing use of modern machining methods such as wire cut EDM, it is necessary to examine the effects of these methods' variables on the properties of metals. In this study, to enhance surface properties during the manufacturing process, cubic samples made of CK45 steel were fabricated using the wire cut method, and the effects of speed and current intensity variables on changes in surface properties including hardness, roughness, wear, and corrosion were discussed. The hardness and weight loss due to wear in the base sample were 218 HV and 18.51 mg, respectively, while in a sample with a manufacturing speed of 80 and a current intensity of 3 amps, these values reached 247.7 HV and 5.62 mg. The highest roughness was recorded in a sample with a manufacturing speed of 50 and a current intensity of 4 amps, and the best and worst corrosion results were observed at a speed of 50 and a current intensity of 3 amps and a speed of 50 and a current intensity of 4 amps, respectively
