S1303-1-3 Study on tool life in simultaneous milling of cast iron and aluminium cast alloy

Abstract

The tool life in milling engine component becomes extremely short when the component has different materials such as iron and aluminum. In this study, suitable tools and machining conditions for simultaneous cutting was investigated. Cemented diamond, cemented carbide and cermet tools were tested. This experiment yields (1) Cemented diamond broke early. (2) Cemented carbide is chipped because of high feed rate per tooth.(3) Cermet may be adapted for simultaneous cutting and cermet can be decrease the manufacturing in cost.
