Abstract In this paper, a state-of-the-art review on cutting tool technology in machining of Ni-based superalloys is presented to better understand the current status and to identify future directions of research and development of cutting tool technologies. First, past review articles related to the machining of Ni-based superalloys are summarized. Then machinability of superalloys is introduced, together with the reported methods used in cutting tool design. The current researches on cutting tools in the machining of superalloys are presented in different categories in terms of tool materials, i.e., carbide, ceramics, and Polycrystalline cubic boron nitride (PCBN). Moreover, a set of research issues are identified and highlighted to improve the machining of superalloys. Finally, discussions on the future development are presented, in the areas of new materials/geometries, functional surfaces on the cutting tool, and data-driven comprehensive optimization.

1 Introduction A cutting tool, considered as the “teeth” of a machine tool, is one of the principal manufacturing resources in the machining field because it is in touch with machined workpiece directly and sometimes directly determines the machining quality and efficiency of the workpiece. However, they have been considered as standard products in practice, so that tool selection is centered in computer-aided process planning [1]. Nevertheless, the research on cutting tools has not been active other than proper selection. It is therefore still challenging to guarantee a long tool life with high quality in machining of difficult-to-cut materials, e.g., superalloys. A superalloy is a high-performance alloy which exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation. Here, Ni-based superalloy is one of the most typical classes of the superalloy, and it is mainly applied in aerospace, oil and gas mining, petrochemical, and other industries.
