Sheet Metal Cnc Automatic Programming Of Visualization Technology Research

With the popularity of NC machine, the requirement for the NC automatically programming technology is more and more highly raised. So, based on the research on the existed automated programming technology and combined with the concurrent developmental orient of NC automated programming, the thesis studies the viewable and reciprocal NC automatically programming technology and its prototype system for the sheet parts.At the beginning of the thesis, it tersely introduces the present condition and development of NC programming technology, and compares and analyses the current NC programming technology. Combined with the structural character of sheet parts, the thesis studies the viewable and reciprocal NC automatically programming technology based on the entity characteristic parameterized modeling technology, and develops a viewable and reciprocal NC automatically programming prototype system for sheet parts.In the paper, drawing lessons from technology approach and thought of finding the solution to problem by separating reason and knowledge in the specialist system, total construct and functional block dividing of system was completed. The thesis brings forward the technological decision-making model based on relation database, realizing the relative separation of technology knowledge data and technological decision-making program. To realize technological decision-making reason, on the basis of analyzing, arranging and constructing technology knowledge data, expression and storage of technology knowledge are realized. According to the destination of the total system construct, all sort of key technology are researched, for example, the parameterized and reciprocal inputting technology of parts information, calculation and automated born of spreading draft, viewable and reciprocal selection of mould, viewable automated born of cutlery center trail and NC program.Finally, in view of Visual Basic 6.0 and Access 2000, the thesis completes the specimen development of prototype system. From the result, it can be expressed that, because of using the parameterized, viewable and reciprocal programming technology, the NC programming is very intuitive, quick, uneasily going wrong and high efficient...
