The paper considers the peculiarities of combined processing of parts, made from extruded metal blanks with anisotropic electrotechnical properties. It involves the application of an electric field and seeks to achieve the required profile accuracy in any processing direction with precision within the specified tolerance for finishing operations. The study describes the specific nature of the development of current leads and the ways of achieving the required accuracy when combining electro-erosion and electrochemical components of the process in real time, taking account of the position of the pressing force vector relative to the direction of current flow in the zone of combined processing. This gives the opportunity to ensure the process stability and accuracy of processing advanced materials with a wide range of current conductivity variation in components, used when extruding blanks for precision parts. The study employs the methodology of calculating and assigning technological modes of combined processing, formed on the basis of the energetic approach and using the principle of similarity in technological systems. It also involves the adapted process management which allowed for elimination of unstable impacts affecting the accuracy of shape formation and surface layer quality, and expands the area of using combined processing for manufacturing extruded parts with anisotropic properties of components. The article presents the feasibility study of the ways of extending the work results to various types of products, particularly, to processing of welded and soldered joints of metallic materials and coated details where the replacement of traditional processing methods with combined ones significantly increases the opportunities for obtaining high-precision parts with required performance characteristics.
