Analysis of Machinability of Inconel 718 in High Speed End Milling with Ceramic Inserts Under Room Temperature Conditions

Analysis of Machinability of Inconel 718 in High Speed End Milling with Ceramic Inserts Under Room Temperature Conditions

Abstract. Inconel 718 is used for high-temperature applications in aerospace, nuclear, and automotive industries due to its resistance, at high temperatures, to corrosion, fatigue, creep, oxidation, and deformation. Unfortunately, these same qualities also impair its machinability and researchers...
