Description
  • Determination of residual stress close to the sample surface is in the most cases performed by hole-drilling method, X-Ray diffraction or neutron diffraction. Each of these methods has its benefits and disadvantages. In case of diffraction methods the measurement speed is the main disadvantage. It is also very problematic to apply diffraction method in case of sample with mechanically deformed surface, for example by standard machining operations. Therefore, determined results are very often confusing and hard to interpret. On the other side, hole drilling method is less sensitive to quality of sample surface than diffraction methods, but measurement realization is quite expensive and equipment demanding (strain gage rosettes, miniature milling cutter, high speed milling machine, pc equipment,...). Recently introduce contour method used for determination of residual stress inside the sample is very fast, can be performed with almost common laboratory equipment and combines traditional stance with modern numerical methods by FEM. Contour method was selected for determination of residual stress below the milled surface and the dependency of milling process quality on residual stress value is demonstrated.
