Interactive communication between the user and the computer-aided design system of shaft forging on presses

Despite the accelerated development of computer technology, programming languages and methods in recent years, computer-aided design of open-die forging on presses is still not widespread due to weak formalization of the subject area. Therefore, the developers of relevant computer-aided systems have to put “approximate” algorithms and programs into the systems for solving technological problems. As a result, they provide users with the ability to adjust design concepts by a graphic dialogue. The paper describes a mechanism of interactive communication between the user and the computer-aided design system of shaft forging on presses, which was developed at the Institute of Engineering Science of the Russian Academy of Sciences (Ural Branch). This system provides wide opportunities for making necessary adjustments in a forging drawing and a forging process map. This ensures obtaining necessary design and process documentation suitable for using in the production process, even when the algorithms and programs are imperfect. Moreover, it significantly facilitates the implementation of the system at various enterprises
