Beketov national university of urban economy in Kharkiv popup.description1 The project aims to significantly increase the efficiency of finishing dimensional machining by using combined electrodes manufactured by additive manufacturing methods and by ensuring the quality and reliability of products in the restoration (repair) and manufacturing of parts of aviation and missile equipment and weapons. popup.description2 The research project is focused on the development and investigation of precision dimensional electrochemical machining technology for complex-shaped parts using combined electrodes manufactured by additive technologies. The relevance of the study is determined by the increasing requirements for dimensional accuracy, surface quality, and reliability of components used in aerospace engineering, defense-related applications, and high-precision mechanical engineering, as well as by the need to improve the efficiency of finishing operations during manufacturing and repair processes. The aim of the research is to establish a scientifically grounded methodological and computational framework for the implementation of precision electrochemical machining processes employing combined electrodes produced by additive manufacturing methods, ensuring process stability, controllability, and predictability of machining results. Within the second stage of the project, the results obtained at previous stages were summarized and consistently integrated into a unified technological concept. During the reporting stage, mathematical models of the electrochemical machining process were refined to account for the coupled hydrodynamic, thermal, and electrochemical phenomena occurring in the interelectrode gap, as well as the differential kinematic characteristics of motion in CNC-based technological systems. A calculation methodology for determining the parameters of precision electrochemical machining was developed and formalized for practical application in technological process planning Numerical and parametric studies were carried out to evaluate the influence of pulsed current parameters, hydrodynamic conditions, and electrode motion characteristics on the key performance indicators of the machining process The obtained results made it possible to refine the requirements for the design of combined electrodes and their operating conditions T Product Description popup.authors Сергій І.
