چکیده انگلیسی
Turning speed, depth of cut, and feed rate are only considered for the traditional turning tool life model of nano ceramic tool. But installation and geometry parameters of the tool and the material characteristics for manufactured materials have not been taken into account for ordinary tool life model. Three-dimensional numerical simulations of turning process using nano ceramic tool have been researched by finite element method (FEM) and archard wear model in the research. The influences of tool shapes, tool rake angle and manufactured metal properties on the contact stresses, sliding speeds, and the temperature have been discussed. A new type of tool life model for nano ceramic tool has been established which include turning speed, depth of cut, the feed amount and other factors. The influences of tool shape, tool rake angle and manufactured metal properties, as well as other turning parameters on tool wear life have been studied deeply. Turning experiments have been done. The preliminary tool life prediction model and evaluation system based on the finite element simulation for nano ceramic tool turning hard steel have been constructed. The model can provide fundamental and practical guidelines of the hard turning.
