New mechanistic cutting force model for milling additive manufactured Inconel 718 considering effects of tool wear evolution and actual tool geometry

Inconel 718 is widely used in aircraft industry due to its properties. Nevertheless, mechanical and chemical properties make it hard-to-cut. As a consequence, additive manufacturing developed order get near net shape part before machining. Thus, this article presents study on the machinability of obtained by compare one from wrought bar. Firstly, milling investigated through microstructure observation cutting forces analysis, then tool wear observations for both material are realised. Thereafter, novel formulations force model associated precise treatment identification process. modelled with mechanistic approach fully parameterized, furthermore geometry as well local consider flank effect. This shows that manufactured has better considering evolution improves precision.
