Edited by . Tonshoff I. Inasaki Copyright 2001 Wiley-VCH Verlag GmbH I 363 ISBNs 3-527-29558-5 Hardcover 3-527-60002-7 Electronic workpiece is moved at a low feed speed until the first chip formation is visible with the naked eye. The precision and consistency of this feed operation depend heavily on the experience of the machine operator and generally fluctuate by at least 1-2 pm. This however is intolerable for demanding applications of the micro-structure technique or for measuring coated sample parts. Environmental Awareness F. Klocke RWTH Aachen Aachen Germany Ecological issues are assuming increasing importance in many areas of the economy as a result of legislation and growing public awareness. Manufacturing characterized by a chain of resource-intensive processes and by large quantities of waste materials and emissions is frequently the focus of interest. Government-imposed environmental regulations and increased cost pressure in conjunction with the need to prevent the production of waste materials or to dispose them appropriately are forcing companies to introduce innovative environmentally compatible manufacturing processes. In the manufacturing environment the starting points for ecologically oriented improvement lie in the need to prevent the generation of waste materials and pollutants in the first place or to reduce the volumes produced and re-use them. The advantages which stand to be gained as a result of the application of more environmentally compatible technologies are clear reduced levels of energy consumption waste and disposal costs together with higher employee motivation and lower rates of absenteeism due to illness 1 . In the successful practical application of process monitoring systems and components monitoring- and sensor-related solutions are adapted to meet the specific requirements of the machining task concerned. This demands precise knowledge of the machining operation ie the manufacturing .
