Tribology of Metal Cutting

The term tribology is from the Greek tribos, meaning friction, and logos, meaning law. Tribology is therefore defined as 'the science and technology of interactive surfaces moving relative to each other'. The science of Tribology concentrates on contact physics and mechanics of moving interfaces that generally involve energy dissipation. To comprehend the scope of metal cutting tribology, it should be clearly realized that the ultimate objective of metal cutting tribology is the reduction of the energy spent in metal cutting. Increased tool life, improved integrity of the machined surface, higher process efficiency and stability are the results of achieving this goal. This book attempts to provide specialists in the field of metal cutting with information on how to make metal cutting tribology useful at various levels (starting with tool design, developing and/or selecting proper tool materials including coating, development and/or selecting proper cutting fluids and ending with cutting process optimization on the shop floor).
