INTEGRATED COMPLEX APPROACH TO GEOMETRIC MODELING OF DISC WORKING PARTS OF SOIL-PROCESSING TOOLS

This article provides the basics of integrated geometric modeling of technical objects using the example of disk working parts of tillage tools. The methods and techniques of shaping technical objects used in this process significantly determine the overall efficiency of the disk working parts of tillage tools during their entire life cycle. The defects of the "traditional" design of the working parts of tillage machines, based on experimental selection, manufacturing of a large number of prototypes and their further testing in various technological modes, are analyzed. The relevance of the search for new and / or adaptation (improvement, generalization, etc.) of the existing methods for designing the working surfaces of tillage tools is shown. Igor Sikorsky on issues of both improving new and developing existing methods of geometric modeling. In particular, special attention is paid to the development of the methodology of structural-parametric geometric modeling, the use of involute-evolute models, the use of surface conjugation theory, namely the formation of a unified methodology for geometric modeling of various technical objects and the processes of their manufacture and operation. A technique for automated geometric modeling of a certain group of technical objects on the example of disk parts of tillage tools used modern computer information technologies is proposed. The main advantage of this approach compared to the existing ones is the creation of the productive formation of a large number of structural-parametric product variants. Also important is the invariant nature of this method of shaping, which extends not only to the field of engineering, but also to other industries, in particular, instrumentation, the aerospace industry, robotics, etc. The given direction makes prospects for further scientific research.
