Information Foundations for Improvement of the System Multilevel Basic Group Technology Mechanical Treatment

Abstract

The information bases and principles for the development of a multilevel basic technology (MBT) system based on the method of analysis and synthesis of design and technological information in the working design documentation of the product are presented. The article deals with the scientific foundations and the Philosophical methodology of the multi-level basic technology system, using the descending and ascending design of technological processes by the "analysis-synthesis" method of design and technological information. The given graphical-text block diagrams allow to consider: - levels of technology and the degree of specification of information; - functions and structure of the MBT system; - a sequence of solving the problems of designing basic and working group technological processes. The application of the synthesis method for solving the problem of searching through technically possible variants of integrable transitions, positions and settings on professional personal computers with the correct filling of the matrix tables by a technologist of medium qualification makes it possible to obtain the optimal for the existing production of the technological processes machining of high-precision turning parts of simple and complex shape. Advantages of the proposed approach in comparison with the traditional ones are a significant increase in the quality of the developed technology and a sharp reduction in the terms of technological preparation of production.
