Assessment of Cooling Effect and Surface Quality to Face Milling of AlMg₃ Using Several Cooling Lubrication Methods

摘要

This article analyzes the temperature variations in the cutting zone under flood of oil-water emulsion (FE), near dry machining (NDM), and dry cutting (DC) conditions. The research compares the dual effects of air-oil mixture in NDM with the cooling effect to DC and FE in terms of the reduction of the cutting temperature through the cooling effect, as well as the reduction of heat generation through the lubricating effect to face milling. The case study concerning the face milling of AlMg₃ and the experimental measurements show the cooling and the lubricating effects in NDM reduce the cutting temperatures on the tool-chip interface with respect to the dry machining. The cutting speed remains a dominant factor in the cutting temperature compared with the feed and the depth of cut in the NDM processes. The other aspect investigated, connected with the cooling and lubrication effects, is the machined surface quality.View full textDownload full textKeywordsCooling effect, Dry cutting, Face milling, Near-dry machining, 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/10.1080/10426914.2011.577864
