Research On Expert System Of Evaluation Report Generation For NC Machine Tool Selection

At present domestic CNC machine tool selection and design of expert system development is still in the initial stage, the present lack of comprehensive performance of mechanical and electrical integration design tools and selection model and corresponding complete support database. Now NC machine tool design, machine, electricity, liquid, control modules were in accordance with their respective designers experience collocation, selection of design standards are not uniform, the at the same time, in the selection and design of domestic CNC machine tool products technical data and configuration design document standards is not perfect, it is not easy to repeated use and access. In view of the above problems, the main research contents are as follows:Intelligent design report of CNC machine tool, automatic generation of needs analysis, framework of constructing the comprehensive evaluation selection design calculation and allocation scheme report generation expert system; the establishment of domestic CNC system, servo driver, servo motor, the typical structure of the machine tool parts or other optional features of the typical database resources; acquisition, representation, from the configuration calculation the rules of knowledge and the structure of the knowledge base, reasoning mechanism, knowledge base maintenance, the modular object-oriented knowledge representation and the selection scheme of fuzzy comprehensive evaluation and so on, can achieve the basic design evaluation redesign ", to ensure the efficiency and rationality of scheme selection results; generating design success the case report, enrich the CNC machine tool products made of the technical data and design documents, in turn Selection of effective guidance for the machine design, shorten the design cycle of the machine, and as new training data based on and become a powerful means of publicity and promotion, support the improvement of the stability of technical quality and reuse technology.Based on the above theoretical technology, the design and evaluation report generation expert system of CNC machine tool is developed, which verifies the feasibility of the key technology and theory in the system.
