MODULAR-GEOMETRIC APPROACH IN AUTOMATED DESIGN OF MECHANICAL ENGINEERING PRODUCTS

Mechanical engineering is one of the basic branches of world industry. The formation of our state as a component of the community of European countries is closely related to it. Therefore, the further development of mechanical engineering by making appropriate improvements to it is quite relevant. A generally recognized direction for improving product quality is computer-aided design, which is quite common in the specified field of activity. This is evidenced by the widespread use of various CAD/CAM/CAE/PDM (Computer-Aided Design/Computer-Aided Manufacturing/Computer-Aided Engineering/Product Data Management) computer systems. Without the latter, it is almost impossible to create world-class technical facilities. This is due to the fact that the specified means make it possible to significantly shorten the design time of products, increase their quality, and reduce manufacturing and operating costs. It is known that geometric modeling is a fundamental component for the creation of many types of industrial products and is an integral element of many modern CAD systems, i.e. automated design systems. Consequently, the corresponding characteristics of the created technical objects significantly depend on the perfection of computer shaping. There are many scientific and methodological approaches to its effective practical implementation. One of them is the methodology of structural-parametric geometric modeling proposed by the scientific school of applied geometry of the National Technical University of Ukraine "Ihor Sikorskyi Kyiv Polytechnic Institute". A progressive direction in mechanical engineering is a modular approach, which is used during the design, manufacture and operation of technical objects. Many issues at different stages of the life cycle are closely related to the geometric parameters of products. Therefore, the scientific and applied task of developing appropriate tools for computer shaping is relevant. This publication is aimed at defining a strategy for solving the described problem. The concept presented in it is based on the principles of structural-parametric methodology
