Abstract: The project is carried out at the Lublin University of Technology within the scientific discipline of Mechanical Engineering. The subject of the project is related to the development and use of advanced digital metrological methods and methodology for identifying internal defects of parts produced in the rolling process and their dimensional and shape compliance after comprehensive machining, taking into account the accumulated stresses around the identified material structure discontinuities. The project consists of two main research tasks, comprehensively covering the full process of producing multi-stage rolled shafts and their finishing machining, in accordance with the idea of "from blank to finished product". One of the tasks is to develop a new criterion for fracture of materials in the processes of metal forming of metals and their alloys, taking into account complex stress states for typical processes of metal forming. The second task consists in the development and practical implementation of intelligent and advanced measurement techniques in the process of identifying internal defects of parts produced in the rolling process and their dimensional and shape compliance after machining, taking into account the accumulated stresses around the identified discontinuities of the internal structure of the material, and the development of prognostic models enabling the prediction of cracks and dimensional incompatibility of the finished product. The implementation of the project is closely related to the development of the scientific discipline Mechanical Engineering and fits perfectly with the goals set by the Central Office of Measures, such as: supporting research and technologies using precise and accurate measurements, implementation of tasks for an innovative and competitive economy, development of modern techniques computing, simulation and methodology of analysis of a large number of variables and diverse data sets, effective operation of the Polish economy and satisfying social needs and adequate quality of life, creating technologically advanced national metrological infrastructure, deepening interinstitutional cooperation and transfer of knowledge and technology - resulting from the growing needs of Polish industry and society, and many more. The results of the project will be used to build predictive models of cracks as well as dimensional and shape inconsistencies, taking into account complex stress states, based on simulation and experimental methods, implemented with the use of advanced intelligent and adaptive measurements with intra-machine measurement systems, as well as autonomous multisensory systems. The developed digital tools will effectively support the Polish economy in the key discipline of mechanical engineering in the field of engineering and technical sciences. According to the main assumptions of the competition, the project will be implemented with the active participation of the Central Office of Measures. The obtained results will allow for the development of new measurement methods, which will significantly contribute to the development of Central Office of Measures, by developing advanced metrological techniques for the accurate detection and prediction of cracks in semi-finished products produced in metal forming and then machined processes.
