Precision machining and especially hard machining is a topic of high interest at present. Surface integrity requirements increase. Precision machining (mostly turning and milling) may substitute some abrasive operations. There are some advantages of precision machining over the abrasive machining. Abrasive machining has traditionally performed the finishing process of hardened steel. But, the availability of hard and super hard cutting tools enable the machine tools to reach surface quality of hard machining like to those obtained in grinding processes. But, precision machining is possible to apply also in machining common materials, not only hard materials. A surface is not only a geometric entity but also a layer with its own structure and properties. These properties are affected by many factors, e. g. by cutting temperatures, friction, deformations in the primary deformation zone and the surface layer of the transient (machined) surface, by cutting tool geometry, work hardening, cutting environment, etc.

Keywords: surface integrity, precision machining, residual stresses, notches
