Surface integrity is a broad term which includes various quality factors affecting the functional properties of parts. Residual stress is one of these factors. Machining generates residual stresses in the surface and subsurface layers of the structural elements. X-ray diffractometry is a non-destructive method applicable for the measurement of residual stresses in surface and subsurface layers of components. The article is focused on the non-destructive progressive method of triaxial measurement of residual stress after machining the surface of sample by high feed milling technology. Significance of triaxial measuring is the capability of measuring in different angles so it is possible to acquire stress tensor containing normal and shear stress components acting in the spot of measuring, using a Cartesian coordinate system.

Application of miniature machining is currently rapidly increasing mainly in biomedical industry and machining of hard-to-machine materials. Machinability of materials with increased level of toughness depends on factors that are important in the final state of surface integrity. Because of this, it is necessary to achieve high precision (varying in microns) in miniature machining. If we want to guarantee machining high precision, it is necessary to analyse tool wear intensity in direct interaction with given machined materials. During long-term cutting process, different cutting wedge deformations occur, leading in most cases to a rapid wear and destruction of the cutting wedge. This article deal with experimental monitoring of tool wear intensity during miniature machining.

The paper deals with the influence of the properties surface layer of notched components. This material is widely used in the automotive industry. This material is subject to different kinds of processing, and therefore present a different quality of the surface layer. For many manufactured components, we find diverse types of notches, such as slots, recesses and holes. They are the place where is stress concentrated, so called the macroscopic stress concentrator. When we focus more on the surface profile, we find the diversity of technologies in the surface, which creates different sizes and shapes of microscopic notches. In these places, there is a higher risk of the destruction of the components. Many designers prescribe unnecessarily high surface quality. It is important to maintain adequate quality of the surface to achieved high durability.
