摘要：
Surface integrity has been an important research topic in the last decades. Machining generates residual stresses in the surface and subsurface layers of the structural elements. The residual stress has a large influence on the functional properties of the components. X-ray diffractometry is a non-destructive method applicable for the measurement of residual stresses in surface and subsurface layers of components. The article deals with the 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. For comparison, a simple measurement of residual stresses in the point indicates the stress direction only in normal direction of the measured surface. (C) 2017 The Authors.
