چکیده مقاله
With the rapid advancement of manufacturing technologies and the increasing demand for precision and high quality industrial components, understanding and controlling machining phenomena are of great importance One of the major undesirable effects in machining is the formation of a built up edge BUE , which significantly affects surface quality, cutting forces, temperature, and tool life This study investigates the influence of machining parameters cutting speed, feed rate, and depth of cut on BUE formation during the turning of aluminum alloy 7075 Owing to its high tensile strength, good fatigue resistance, and excellent machinability, this alloy is widely used in aerospace, automotive, and marine industries Experiments were conducted using a TN 50B lathe and K20 grade tungsten carbide tools The experimental design followed the Taguchi method, and data were analyzed using analysis of variance ANOVA Results showed that higher cutting speeds and greater depths of cut increased both the BUE height and process temperature, whereas the feed rate had a lesser effect The maximum BUE height of 0 52 mm occurred at a cutting speed of 19 725 m/min and a depth of cut of 4 mm To improve tool performance, graphene coating was applied to the cutting tool surface Comparative tests revealed that the coating reduced the process temperature by about 7°C and significantly diminished or eliminated BUE formation Therefore, graphene coated tools can effectively enhance tool life, surface finish, and machining stability when turning aluminum alloy 7075
