By adopting the parameterized designing method of f ea ture assembled and feature unit, for the feature of non-conventional type parts , such as welding box and bearer, by use of Visual C++ and AutoCAD a s soft tools, the system can successfully carry out the basic function of featur e assembled, the processing of two-dimensional figure, the building of three-d imensional feature, the automatic producing of technical papers, and so on. The thoughts and design methods of this system can be served as the preference to CA D/CAPP integrated for othernon-conventional type parts. For non-conventional parts, its feature is too much, so the parameter is much. By adopting interactive entry for graphic parameter, under the control of main c ontrol module, through inputting the feature parameter and calling the feature g raphic unit, the function for modeling is completed. To reduce input of feature parameter, the description of position feature is adopted in the feature descrip tion of non-conventional parts, that is, fix position is constraint through str ucture and dimension of non-conventional parts. In such a manner, the assembled process has been transformed the coordinate conversion process, and this is ver y important in the production of three-dimensional graphics. In the one hand, b y calling the feature of parts in the library of feature-graphic unit, the two -dimensional DXF file and three-dimensional SCR file are automatically produce d in AutoCAD. On the other hand, by calling the rules and standard operational s equences in the technologic knowledge base, through inferring of inference engin e, the assembled sequence of non-conventional parts and welding sequences are a utomatically produced. The two aspects constitute overall design philosophy for system. So the CAD/CAPP integration of feature-assembled for non-conventio nal parts are completed. The principle of dividing feature is based on the thought of group technology, t hat is, according to the function feature of parts. The feature-assembled p arameterized design method is to divide the parts into many feature-units, acco rding to the structure, function, and secondary feature, and the each unit is in teractively produced, so the whole part is assembled gradually. At the same time , to display the sequences which deviser chooses varied features, hidden feature code is adopted. The feature-unit parameterized design method is to assemble dimension, margin tolerance and fitting-in, and surface roughness into one unit that it becomes a fixed structure. However big it is, it could be added to or taken off like a ba sic feature-unit.By adopting above-mentioned methods, the module of parts is e stablished. Under the integrated environment, according to basic construct of expert system, CAPP system is made up of three sectionsdynamic database (document-view ), knowledge library and inference engine. Dynamic database is served as storing initialized and middle information as well as ultimate design result. The knowl edge library is composed of static database, rule set, and standard welding proc ess library. 展开更多

Product data management (PDM) is a new technique that is developed from database management system (DBMS) to manage the information and the associated procedure of a product. Many design engineers have employed PDM tools to coordinate and control access to documented versions of product designs. But it is still a focus of research efforts in industry and academic how to further build an efficient and effective integrated product/process development environments (IPDEs) based on PDM to meet requirements of enterprises. This paper introduces the approach to design and implementation of an integrated CAD/CAPP system (IC2S) based on PDM. This system is an important compent of computer integrated manufacturing system in KELON Inc(Kelon-CIMS). It is mainly used to support for the design and development of the home electric appliances (HEA). 展开更多

Some key issues in supporting collaborative design in product data management(PDM ) system and 3D computer aided design(CAD) system integrated environment are analyzed. The general architecture of the integrated environment is divided into five tiers and employs the transparently integrated mode, with the mode, function calling and information exchanging among independent PDM and CAD processes are carried out via message translation /parse approach. Product layout feature(PLF ) model definition is presented, PLF model is used to represent design intention at the preliminary design phase. The collaborative design methodology employing the PLF model in PDM/3D CAD integrated environment is analyzed.

CAD technique and its software products have been d ev eloped independently of CAPP, but the market’s requirements on reducing lead-t ime of a new product and promoting automation of design and manufacture processe s need integration of CAPP with CAD. The base of CAXs’ integration in product d esign and manufacture is information integration. There are several information integration approaches, for example, by data format transition through special d ata interface, or by standard format file for data exchange (e.g. based on S TEP),etc, but the integrating approach based on PDM is a more advanced and effic ient one. The approach is based on a common database. The feature model data of a product created by the CAD sub-system is stored in the common database, and the CAPP or CAM sub-system can get access to the data for its own work, by whic h repeated input of the data is avoided and data redundancy is eliminated. T he integration approach of CAPP with CAD discussed in this paper is based on the approach. Solid Edge, one of the CAD software products of UGS company is a 3-D modeling software based on parametric feature modeling technique, which is easy to learn and use, so suitable for small and medium manufacturers’ application. The feature data of the part model created by Solid Edge Part includes geometri c and topologic information of the part which provides basic data needed by CAPP , but like other 3-D feature-based modeling software, no precision and materia l information which is also essential for CAPP. In this paper, an approach is pr esented by which the precision features and material features of the part are ad ded into the 3-D CAD part model of geometric feature. So-called precision features include dimension tolerance, shape tolerance and position tolerance and so-called material features include material type and hardness. All these data are expressed by a set of characters which, combined with the surface t ype name of the related geometric feature, is substituted for the original syste m name of the geometric feature by using the rename function of the feature tree in the EdgeBar of "Solid Edge Part" GUI. If a feature joint of the feature tree is pointed by the mouse cursor, the related profile of the model in the working area of Solid Edge Part GUI is highlighted. In this visual way, precision featu res and material features of the part are added into the part model and for each geometric feature of a part model, the surface type and dimensions created by t he 3-D feature-based modeling software are combined with the precision and mat erial properties added. Then by a VB program, all these feature data are extract ed from the model and stored in a feature table of the common database ready for CAPP visit. The database is built by using Microsoft Access. The precision feat ures and material features data are obtained by applying "split" function of VB to the character set extracted as the name property of each geometric feature ob ject of the part model. The VB program can be made a custom-defined menu comman d running in the GUI of Solid Edge Part. All of the other related key techniques are detailed in the paper and an example is given. 展开更多

This paper addresses some key issues in supporting product family design in a 3 D CAD/ PDM integrated system and introduces the techniques developed or adopted in building the integrated system. The general architecture of a 3D CAD/PDM integrated system is organized as five tiers. Multi-agent technology is applied with a collaborative design environment. The rule-based product family architecture ( PFA ) and tabular layouts of article characteristics (TLAC) technique are applied to represent the knowledge for product families. They make the knowledge understandable, simplified and can be exchanged among heterogeneous information systems. A transparently concentric integrated mode is put forward to enable the heterogeneous processes to interact and communicate regardless of the language used to construct each process. With the mode, function calling and information exchanging among different processes are carried out via message translation/parse approach. Currently, the integrated system is implemented in the platform of Windows NT and 2000. 展开更多
