Drilling of SiCp/Al Metal Matrix Composites with Polycrystalline Diamond (PCD) Tools

摘要

High-volume-fraction SiCp/Al composites have attracted considerable interest for their excellent thermo-physical properties. However, popularization of high volume fraction SiCp/Al composites is still hampered by their poor machinability. In this study, the influences of the cutting speed and feed rate on the drilling performance of SiCp/Al composites with 56% SiC particles were investigated experimentally. The drilling characteristics were evaluated in terms of drilling forces, tool wear, and the surface quality of drilled-hole. It was found that the feed rate is one of the main cutting parameters that affect the drilling performance, while the cutting speed has no significant effect on the thrust force.View full textDownload full textKeywordsDrilling, PCD tools, SiCp/Al composites, Tool wearRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426914.2011.654152
