Integration of Technological Preparation of Production into Automated Design Systems

Abstract

The concept of the development of an integrated system for the design of technological processes for the manufacture of mechanical engineering products is considered. The research relates to the field of automation of technological preparation of production in the development of the technological process of manufacturing a product (part, assembly unit). An algorithm for automated analysis of a three-dimensional product model (CAD model) made by the KIT system (KIT-computer information technology) is proposed to identify and formalize significant product parameters. As a discrete element of the part, a structural element is considered as the basis for choosing the manufacturing technology of the product as a whole. The general functional structure of the system being developed is described, which is necessary for the formation of the product manufacturing route taking into account the production process data structured in the product database. The practical result of the system when introduced into production is a reduction in the cycle of technological preparation for the release of a new product. The system allows you to design route-operational TP for all technological conversions of the enterprise. It is possible to design technologies for a group of parts. There are no restrictions on the size of the TP. The volume of the Database of Technological Design (BDTP) to date is more than 7000 technological processes, including existing production and discontinued products. The number of jobs on the enterprise network for the system is more than 150, the degree of coverage of the technological design system in the main production is 100 %.
