Abstract

The increase of demands for products miniaturization has led to a need to research and explore the possibilities of micro-machining of special alloys. This paper presents the experimental study on the micro-milling of Inconel 718 super alloy. It is austenitic nickel-chromium based material which is oxidation resistant. Inconel 718 super alloy is used in the aerospace, automotive and energetic device industry. It applies for extreme environments subjected to high pressure and high temperatures. In this study, mentioned super alloy is machined with long neck micro-end-mill with diameter 0.6 mm, which is intended for side and channel milling of high aspect ratio features. The effects of cutting parameters on output machinability parameters were monitored. During experimental research, there are made conclusions about surface roughness, build-up on edges, cutting forces and etc. For purposes of practical application, general indicative data, area of cutting parameter values, and guidelines for micro-machining of Inconel 718 are given.
