Digital image analysis (DIC) is a non-contact method of measuring deformations (displacement of an object) that compares the displacements of certain points on the object, which are visible in the recorded images. By comparing images of two different states: before and after deformation, the displacement of a certain point on the object is determined. Tracking the displacement of characteristic points on the surface of the measuring sample is achieved by analyzing a series of digital images. The dot pattern is obtained by lightly applying paint from a spray to the measuring surface. The method of digital image correlation (before and after displacement) gives reliable results of mechanical testing, it is very simple and economically acceptable, so it is used more and more today. This paper first describes the DIC method and its application possibilities. Then the methods of obtaining an artificial texture are described and the accuracy of using this method is shown. After that, the test plan for oscillations of the tool holder is presented. At the end of the work, the obtained measurement results were analyzed, with the help of which a conclusion was reached.
