Statistical Analysis of Inconel-600 Micro-Milling

Abstract

Increasing demand of micro scale components in the industry of electronics, aerospace, automotive and biomedical has opened up a door where there is strong research potential in the field of micro machining Micro machining is one the best process for the mass production of 3D micro product with a micron level accuracy. Micro milling is one of the most efficient process is the micro machining technology. Inconel based alloys are suitable to be used as work piece material for different applications in these industries. Most of the previous research has been done on Inconel-718 and comparatively very less research is found on Inconel-600. Inconel 600 has high-strength, corrosion-resistant nickel chromium which is mostly used at high temperature (-423° to 1300°F). Due to its high strength and work-hardening characteristics proper tool materials, tool coating and operating parameters should be selected. So Inconel-600 has been selected to check the effect of input parameters on quality of work pieces. In this research, feed per tooth, cutting velocity, depth of cut and tool coating are considered as input parameters and their effect on surface roughness and burr formation are analyzed through statistical technique of analysis of variance (ANOVA) to determine key process variables.
