Abstract

Ni-based superalloys have excellent high-temperature mechanical properties and are widely applied in aerospace, energy/power, and nuclear power etc. where extreme working conditions as high temperature and high pressure are accounted. This report will introduce the state of research activities on high-performance machining of Ni-based superalloys using advanced ceramics and polycrystalline cubic boron nitride (PCBN) tool materials in combination with typical superalloy and component. The report will focus on the tool performance evaluation and analysis, and characterization of surface integrity in the high-performance machining of such alloys. Engineering and scientific issues related to industrial production of Ni-based superalloy components will also be discussed in the report.
