Toolkit for preliminary design at the stages of developing a control system for a flexible production area

Abstract

Based on analysis of the traditional stages of computer-aided design (CAD), especially at the stages of preliminary and detailed design, the main problems leading to insufficiently accurate engineering, experimental and software results in the development of an automated control and monitoring system for flexible production area (FPA) in the field of mechanical engineering are identified. Based on the initial data of the terms of reference for the computer-aided design process, its modern tools, as well as the requirements and tasks, standards for the design stages, especially the stages of preliminary and working design, a block diagram of the computer-aided design of the FPA control system with adetailed presentation of these stages is proposed. According to the layout diagram of the object of study of FPA for cutting and annealing in the production of aluminum evaporators for domestic refrigerators, the types, functions and positioning of information and measuring tools on the active elements of the production site are determined. To describe the initial positioning data and geometric data of sensors, control elements of the FPA control system in the form of logical links, descriptive products, coordinates, and expressions in the form of mathematical conditions for positioning sensors in a 3-dimensional coordinate system are given. The characteristics of the functions of the information-measuring and control system of the studied FPA are determined, their coordinates are determined depending on the measurement and implementation of the positions of the active elements, the routes for manufacturing the production product and the automation scheme.
