Modern automated production requires technologies to provide stability in machining procedures and the absolute repeatability of the quality parameters obtained on the parts produced. Without the development of a new level of ESM procedures, the generation and implementation of technological equipment, and its complex functioning, it is impossible to produce new generation GTE for modern civil and military aircraft, as well as ships and power plants. For this purpose, issues of the technology to be created for electrochemical rotary machining of GTE blading elements have been considered, including the following aspects: features of the technology of automated GTE compressor blades manufacture, kinematic schemes of work motions of tool electrodes, and constructions of tool electrodes for electrochemical rotary machining. New engineering solutions have been offered that considerably increase the efficiency of the rotary electrochemical machining of gas turbine engine blading elements.
