インコネル 718 のセラミックエンドミル高速切削に及ぼすガスブローの影響

抄録

Machinability of Inconel 718 is remarkably poor, so cutting is carried out in the low speed region at the production site. On the other hand, in recent years, high-efficiency cutting by using a ceramic end mill has been put to practical use in rough machining, but there are some problems such as welding on tools, short tool life, poor finished surface. In this study, the influence of gas blow supply to cutting point on welding and tool life in high-speed cutting of Inconel 718 was investigated.
