Dwindling reserves of raw materials in conjunction with the resultant rises in the price of energy and raw materials, serve to emphasise the importance of increasing the energy and material-related efficiency of manufacturing processes. The investigations detailed here, focus on machining processes and illustrate the pivotal importance of tool selection and the associated selection of process parameters to the subsequent energy efficiency of the manufacturing process. A number of processes with a range of target values were investigated on the basis of experimental analyses of drilling into solid material and of cylindrical hard turning processes. The results demonstrate that universally valid criteria relating to the selection of machine tools and parameters in metal cutting processes can initially be set out. There is some potential for further increases in resource efficiency by optimising processes and applications.
