The development of high performance grinding machines together with the latest superabrasive technology has the potential to impact significantly on existing process chains. Abrasive machining is one material removal process that has the potential to span several orders of magnitude in terms of stock removal. This ranges from high efficiency deep grinding (HEDG) which can now compete with conventional cutting processes and provides the potential for improved surface integrity, surface finish

Thus, using a single machine tool and a single set-up, exceptionally high stock removal rates are achievable in a roughing cycle followed by superfinishing to generate the required surface characteristics and profile, providing higher precision and reduced manufacturing costs. At one extreme, high efficiency deep grinding (HEDG) provides the potential to achieve material removal rates that may compete with conventional cutting processes [2,3], whilst precision grinding provides levels of surface finish and form accuracy difficult to achieve by other machining processes [4][5][6][7][8][9] leading to the possibility of eliminating honing and polishing processes.
