RELATIONSHIP BETWEEN MACHINING FORCES AND DIAMOND TOOL WEAR DURING DUCTILE REGIME MACHINING OF SILICON NITRIDE

摘要

Silicon nitride by nature is hard and brittle. In previous works, it has been demonstrated that silicon nitride can be machined by single-edge diamond tool as an alternative to the traditional finishing process. But commercial viability of such diamond turning processes is limited by tool wear. In this paper, an attempt has been made to edge machine silicon nitride disks with diamond tools of different geometries and operating conditions. Amount of tool wear under these operating conditions is studied and characterized. Our studies show that radius tools perform better than straight-edged tools but with a cost trade-off.View full textDownload full textKeywordsdiamond tool wear, edge cutting, machining forces, silicon nitride, surface roughnessRelated 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/10.1080/10910344.2012.648556
