Abstract
Introduction. Pilot production plays an important role in modern mechanical engineering. Copy-piercing electrical discharge machining (CPEDM) technology has become widespread in machining pilot parts manufactured in flexible production flows. Manufacturing tool-electrodes (TE) is one of the main stages of the CPEDM technological cycle. Purpose of the work. Review of existing studies of modern methods of manufacturing tool-electrodes for electrical discharge machining. Research methods. A literature review of studies in the field of electrical discharge machining devoted to tool-electrodes, carried out mainly over the past 20 years, is presented. Various configurations of structural elements machined using CPEDM technology, as well as TE configurations for their machining, are described. The dependences of the influence of the geometric parameters of the simplest TE configurations on the output parameters of CPEDM are shown. The main groups of TE manufacturing methods are identified. The limitations, advantages, and disadvantages of alternative methods to traditional ones are described. The main trends in the development of modern TE manufacturing methods are revealed. Results and discussion. Based on the literature review of modern research in the field of electrical discharge machining, current trends in the development of tool-electrode configurations are presented, and problems in the manufacture of complex-shaped tool-electrodes using traditional methods are identified. It has been established that among the alternative methods for manufacturing tool-electrodes, investment casting, powder metallurgy, and additive methods are of greatest interest to modern scientists. It has been shown that each method has its own advantages and disadvantages, confirmed by a number of studies. The following current areas of development of complex-shaped tool-electrodes and methods for their manufacture are highlighted: topological optimization of tool-electrodes, use of modern high-tech casting methods; expansion of the range of tool-electrodes materials with improved electrical discharge properties; optimization of powder metallurgy modes, FDM printing, and selective laser melting; increasing the thickness and quality of tool-electrodes coatings obtained using rapid prototyping technologies.
