【 摘 要 】

A turning test on aluminium-basedmetal-matrix composites (MMCs) (aluminium-30% silicon carbide) wasperformed with K-20 carbide tool material and wear patterns and the wearland growth rates were analysed to evaluate the wear characteristicsand to classify the relationship between the physical (mechanical)properties and the flank wear of cutting tools. The study was alsoextended to the machining aspects and the width of cuts on MMCs and theinfluence of various cutting parameters. The experiments were conductedto measure the temperature along the cutting tool edge usingthermocouple at various cutting speeds, and depth of cuts, keeping thefeed rate constant while turning with K-20 carbide cutting tool. Thefinite-element method was used to simulate the orthogonal cutting ofaluminium-based MMCs. The heat generation at the chip-tool interface,frictional heat generation at the tool flank, and the heat generation atthe work tool interface were calculated analytically and imposed asboundary conditions. The analysis of the steady-state heat transfer wascarried out and the temperature distribution at cutting edge, shearzone, and interface regions have been reported.
