Arsecularatnea,*, L.C. Zhanga, C. Montrossb a teach of Aerospace, Mechanical and Mechatronic Engineering, The University of Sydney, Sydney, NSW 2006, Australia b Ringwood Superabrasives Pty Ltd, 111 Gladstone Street, Fyshwick, ACT 2609, Australia real 4 April 2005; accepted 4 July 2005 Available online 19 princely 2005 filch The habiliment mechanisms of cutting tools made of tungsten-carbide (WC), PCBN and PCD were investigated using the tool life and temperature results available in the literature. For tool/ scarper combinations WC/ steel and PCBN/hardened-steel, to a lower place practical conditions, tool wear was found to be greatly in?uenced by the temperature. It was reason out that the most likely possessive tool wear mechanism for WC is diffusion and that for PCBN i s chemical wear. For PCD, more than experimental results and hence and research is required to destine the dominant wear mechanism. q 2005 Elsevier Ltd. every rights reserved.

Introduction An ability to herald the tool life during machining is needful for the design of cutting tools and the close of cutting conditions and tool pitch strategies. The extensive research in this area during the past nose candy or so has contributed greatly to our understanding of the problem. However, there is as yet no machining surmise to provide adequate relationships surrounded by tool life and cutting conditions, tool geometrical parameters and, work and tool material properties. any(prenominal) of the major dif?culties are: (i) the complexity of the machining change which involves extreme conditions of genuinely high strains, strain-rates and temperatures, and (ii) lack of suitable data. Moreover, t ool life depends on a number of variables wh! ich include the mold tool, tool...If you want to cop a full essay, order it on our website: OrderEssay.net
