Micro milling of super alloy materials such as nickel based alloys is challenging due to the excellent of its mechanical properties.
Introduction Inconel 718 is categorized as super alloy or nickel base alloy materials.
The materials adhered to the cutting tool and built up edge was due to the ductile nature of workpiece material.
It was due to the increasing of cutting temperature over the melting temperature of coating materials build up edge.
