OBRABOTKA METALLOV

Introduction. The rocket and space industry is one of the most complex industries, it continuously poses more and more complex tasks, the solution of which is possible only with the advent of new and unique technologies. Today, as before, the space rocket industry faces super-ambitious tasks both to improve the spacecraft themselves and to reduce the cost of their production. The cost of a single spacecraft launch is estimated at billions of rubles; this dramatically slows down the development of the industry and therefore requires maximum attention. The high cost of machining parts of the rocket and space industry is due to the many complexities involved in complicating the design of parts, in the use of superalloys capable of operating under extreme conditions of high temperatures and loads, and therefore difficult to process, as well as in increased requirements for quality. In this connection, today, as well as the most urgently needed, new approaches to processing, which in turn are reflected in the high complexity of technological design and the long production time. The purpose of the work: the development of a method for the maximum reduction of labor-intensiveness and terms of designing effective processing of complex parts of the rocket and space industry. Research methods: Large reserves to improve the technology of processing parts, as well as reducing production time lie in the field of digital technology. Therefore, the main research method is finding bottlenecks in CAM-systems, as well as successful cases on automating the design tasks for efficient processing of especially parts from materials that are difficult to process. Results and discussion: Analysis of the issue showed that when designing the processing in the CAM system there are no close links between the control program and technology, machine, tool and detail, these links are still implemented by a person and directly depend on his experience, which makes the design not quality, not effective and increasingly not profitable. Automating such connections will improve the quality of the design and the processing itself, free up human resources from routine work, and also reduce the time and complexity of the design, which will positively affect the results and cost of production of rocket and space technology. The result of this automation is an intelligent processing module for the CAM system. Some of the tasks solved by the module, and implemented as independent libraries, have already successfully established themselves and are being used in various enterprises.
