The Concept of a Software Module for Automating the Route Design of Mechanical Processing Machine Parts for Use as Part of a Machine-Building CAD System

The article is devoted to the issues of automating the process of designing a technological route for machining machine parts. The problems of modern CAD systems that provide similar functionality, methods and approaches to building software modules for automating route design based on advanced scientific developments in this area are considered. An approach to route design based on network programming methods, graph theory and a probabilistic approach to meeting the specified requirements for the accuracy and quality of the machined surface is proposed. The approach involves the reduction of existing reference data on various parameters of the cutting process into a single structure - “tables of accuracy”. Using the methods of mathematical statistics, the probability of achieving certain quality indicators for various machining methods is estimated. Thus, the issue of route design comes down to solving an optimization problem with a number of restrictions (the probability of achieving the required operational properties of the surface, the range of machine tools, etc.) and the objective function - for example, the cost, the shortest route in terms of the number of technological operations and technological installations, etc. An approach is also proposed for integrating such a system in parallel with the process of designing and layout of technological documentation, linking to an electronic digital model of a part (electronic product passport).
