An Aided Designing System Based On Pattern Classifying And Recognizing

The general and applied system is for the aided design of extrusion aluminum-type materials including aided design system of products and moulds. The application of extrusion aluminum-type materials is very extensive. The characteristics of variety, small batch and aggravation of the market competition demand for short running of designing and producing. Trough the analysis to the section of aluminum-type materials, we find the products' form is regular. So my system applies the method of figures for classifying and recognizing to decompound the section of extrusion aluminum-type materials. The forms decompounded are called the basical forms. All of the extrusion aluminum-type materials can be composed of the basical forms. Through the compounding of the bascial forms, the aluminum-type section is classified so that we can recognize easily on the base of drawing. Using the flexible coding method then, the system matches each product designed by China's Straight Software(华正软件) with aluminium alloy section categorized project. Having realized the fast search of the existing drawing, the drawings of products searched out can be called in China's Straight Software and dealt with. So we can realize aided design variationally and shorten the designing time of the products drawing. According to the characteristic that pinch mould picture number corresponds with picture of products drawing, the mould drawing can be searched out accordingly too and called by China Straight Software to deal with and realize aided design variationally and accelerate the designing cycle of the mould after the products drawings are searched out. Aided design system products increase attribute in product manage also. The aided design mould system is based on existing extrusion equipment, combing existing pinking the structure chart of mould and already using the ripe theory of pinch sets up all pinch theory knowledges, pinch equipment materials and pinch craft data and mould manufacturing engineering data base, etc. According to shape characteristic and geometrical nature of type materials section, it can adopt human -computer interaction way to account pinch parameters and design moulds, produce the processing technology card of mould. It has improved mould design and process quality and reduced manufacturing expense of moulds. This paper explained the method of figures classifying and recognizing and flexible coding method in detail and introduced the joining between this system and China Straight Software.
