Based On The Complexity Of The Knowledge Engineering (kbe) Tool System Design And Research

Entering the knowledge-economic epoch, the development of the world economy depends more on the diffuse and the application of the knowledge than ever. And how to use the knowledge and use it correctly in a enterprise concerns the enterprise can survive or not in the furious market competition in the future.The complicated profiled parts have been widely used in every industrial sections, for instance , separate gear cam unequally spaced airscrew steam turbine fam unequally spaced lead screw and various exploratory etc. in the section of tools manufacturing ,the complicated profiled is more widely used, for example ,complex cutter. It is a more important and more difficult work in the mechanical manufacturing section that how to design and manufacturing complex tools. There was not universal formative principle and method, solving this problem, practice and test were recurred to, and test and try was also another method. But the methods above can't accord with the request of precision. And the cost of the design and manufacturing of complex tools was very high. So another new concept -knowledge based engineering(KBE) was introduced into this paper.KBE is a new-style intelligent method which depends on knowledge, and the design and research of the complex cutter based on KBE has changed the traditional method of the parametric CAD design, and has fetched up the shortcomings of CAD. It will start a new method in the intelligent design field.In this paper ,the developments of all kinds of new technologies around the world and in china were analyzed firstly, and the author thought it's very necessary to introduce the KBE technology. Then many details about the formed cutter were introduced. Next the key technology such as expert system repository database the express and acquisition of knowledge reasoning mechanism and control strategy were detailed illustrated. Next the implementary route was given in this system. At the same time, the graphic user interface was finished and an example was given. At last ,the shortage of this paper was summarized and the prospect of this new technology was probed.Using the method given in this paper, the level of design quality efficiency of formed cutter can enhanced, and it can meet the need of system integrated. And I believe that it will be more widely used in the future.
