Lototska O. Complex technology of microrelief forming on the printing machines parts cylindrical surfaces

The thesis is devoted to the regular microrelief forming by the complex manufacturing process of vibration rolling with further chroming that is to provide the printing machines parts quality and service characteristics increasing. The method of regular microrelief forming on the printing machines parts cylindrical surfaces is developed. On the base of the developed mathematical models the machining conditions influence on wear intensity, stresses and strains intensity distribution while indentation of deforming element, stresses distribution in the workpieces under loading as well as permanent stresses and strains are theoretically investigated. The analytic dependency relations between regular microrelief parameters and machining conditions are estimated to provide printing machines parts quality control and predict their service characteristics. The algorithm and softwear for calculating of geometrical parameters in the process of partly regular microrelief surfacing and further chroming are carried out that makes possible to optimize the machining conditions of manufacturing and recovering of printing machines parts to increase their service characteristics. The results of comparative experimental data laboratory and manufacture investigations of microrelief geometric parameters are presented. New design and technology solutions for regular microrelief forming are carried out. The results of theoretical and experimental investigations are used in teaching process and are applied to manufacturing.
