Abstract

The investigation was carried out on tungsten-chromium-vanadium steel 80WQVS according to DIN standard intended for cold and hot work on which different heat treatment and machining procedures were applied. The results of the investigation were obtained by residual stress measurements on the basis of relaxation method and electro-chemical removal of the surface layer under analysis. The applications of grinding on hardened steel produces compressive residual stresses in the surface layer which range between 400 and 900 N/mrrr in dependence upon the kind of the grinding procedure. 1 Introduction In the last decade the focus of numerous investigations has been to build such an information system whose data files and software would enable the integration of the design and the manufacturing process. The results of all these activities should give a high quality product which would
