Edward Moor Trent was born in England and was the first to describe the diffusion wear mechanisms in tungsten-carbide-cobalt cutting tools. This work was the foundation for new grades of carbide for cutting steels, and subsequently for the development of coated cutting tools. Trent was a prominent lecturer in the Industrial Metallurgy Dept. at Birmingham University and was awarded the "Hadfield Medal" by the Iron and Steel Institute in recognition of his contributions to metallurgy. His accomplishments are highly regarded among professionals in the field today. Founding author of this book.Paul Kenneth Wright (PhD) is prominent in the field and was formerly a professor of mechanical engineering and co-chairman of the Management of Technology Program at the University of California/Berkeley School of Engineering. He has written numerous articles for journals, conferences, and symposiums, as well as coauthored "Manufacturing Intelligence," with D.A. Bourne. In addition, he has served as a consultant and has been involved in many professional organizations.Peter Albany Dearnley (PhD) formerly: Visiting Professor University of Southampton, UK, Senior Lecturer University of Leeds, UK.; Senior Lecturer University of Auckland, NZ., Senior Research Associate University of Cambridge, Research Fellow University of Birmingham, Research Technologist Sandvik Hard Materials Ltd, UK. Awarded (with Mr A N Grearson of Sandvik Hard Materials) the 1987 "Pfeil Medal" by the Institute of Materials, in recognition of their major contribution to understanding cutting tool wear mechanisms when machining titanium alloys.
