Development and application of I-DEAS (integrated design engineering software) were performed in view of actual plastics molding. The results show that plastics molding CAD/CAM/CAE system is a practical and efficient technique which is worth spreading.KEY WORDS: plastics molding CAD/CAM/CAE； integrated； I-DEAS1.1. introductionPlastics molding is the main method of producing plastics product. It develops in high speed but its history is short. Plastics molding is also used extensively. According to the statistics, the quantity of plastics molding is about 28% of that of all molding, but the traditional design of plastics molding is low efficient, long periodic and wasteful. It contradicts with the development of plastics industry. With the development of technique in computer, numerical control and plastics fluid, plastics molding CAD/CAM/CAE has been applied extensively at present2. plastics Molding CAD/CAM/CAE system2.1 process of plastics molding CAD/CAM/CAEThe integration of CAD/CAM/CAE changes the traditional mode of producing molding. Fig.1 show the integrated process.In traditional design, it is required to produce actual solid molding to evaluate the appearance and test the function of product when the product construction is finished. By contrast, in CAD/CAM/CAE system, by using solid geometry modeling users can display the picture of product vividly on graphic terminal, evaluate the appearance and modeling technology through observing the screen, and need not produce actual solid modeling. By using finite 第 2 页Fig1 process of plastics molding CAD/CAM/CAEElement method analysis software, users can also test the mechanical functions of product. The main feature of CAD/CAM system is the generation of a common database which is used for all design and manufacturing activities, so another function of geometry modeling is to provide geometry data for the families of plastics analysis and graphic numerical control, hence the redundant data is avoided, and the efficiency and prevision are improved. Three dimensional geometry solids can also be converted into two dimensional engineering drawing, so designer would be relaxed from drafting and calculating, concentrated on creative work.When finishing the preliminary design, users could check the molding technology and the extent of molding construction by using CAE software, that is to say, users should simulate the process of plastics injection before the molding is manufactured. Through the analysis of CAE software, all kinds of results are gotten in each phase of plastics injection, such as temperature, pressure, stress, filling time, cooling time, warp age and shrinkage, etc. these results are also shown with abundant modes of post process. Users can perform a quantitative or qualitative analysis. If there are some problem, the design could be correct in computer. the interaction is operated between CAD and CAE until the reasonable results are gotten. Not as the traditional process, the molding would be modified when it has been manufactured if something is wrong, so process period i shorten dramatically, and efficiency and prevision are improved. When 第 3 页injecting simulation is finished, if the results are reasonable, it shows the design is applicable. The next step is to finish detail design and manufacturing technology, prepare to manufacture.Recently, the technique of numerical control (NC) makes a great progress. The automatically programmed tool (APT) appeared in 1960s promoted the development of NC technology dramatically. APT is also used widely at present, but it also has some defects, such as low efficiency, etc. at present, the development orientation of NC is to merge CAD and CAM into an organic whole, so CAD/CAM is a unified software system, in which the CAD portion is interfaced inside the computer with the CAM system. Therefore the track of cutting tool is created with the mode of man-machine interaction by using the geometry data fully which is created in the phase of CAD. Now a new programming technique has been come into usinggraphic numerical control (GNC) based on graphic. In the system, cutting tool, workpiece and fixture are displayed on computer screen by generating animation, so the track of tool is optimum and safety. In sum, GNC system is very efficient and convenient.2.2 application of I-DEAS software in practiceOur advanced manufacturing technology center (AMMTEC) of harbin institute of technology makes an effort to develop integrated system of CAD/CAM/CAE. AMTEC was founded in 1992. it imported many NC machines and large style engineering software IDEAS (integrated-design engineering analysis software) with which equips IBM-RISC 6000 work station, so we have the condition to apply plastics molding CAD/CAM/CAE system to design, analysis and manufacturing of plastics molding .I-DEAS is a type of synthetically automatic software. It integrates the functions of design, drawing, engineering analysis, digital simulation of plastics molding, numerical control programming and test. The families of geometry modeling, plastics analysis and graphic numerical control constitute a plastics molding CAD/CAM/CAE system. We would design and manufacture a set of molding which produces the plastic pedal of “jetta” car (product material is nylon-66) for the first Automobile Work of city of changchun. It is difficulty to design and manufacture the molding because the shape of pedal is very complicated, so we decided to apply the families of I-DEAS to design, analysis and NC programming.I-DEAS solid modeling is an important component of I-DEAS. It supplies a set of functional tool for geometry modeling and detail mechanical design. The method of solid modeling is constructive solid geometry (CSG). The steps are in following:(1) creating basic elements, such as cubic, cylinder, sphere, etc.(2) disposing the basic elements by using Boolean operation. So the complicated geometry can be created.第 4 页Using these steps, the three dimensional geometry modeling of pedal can be created. computer graphics enable the designer to study the object by rotating it on screen, enlarging a specific portion of the object to observe it in detail.Finishing the preliminary design of molding, we can perform an injecting simulation to evaluate the design by using the family of plastics analysis which uses finite element method. I-DEAS provides three methods of creating the geometry shape of finite element.from the family of solid modeling.From the family of itself.From other CAD system.Because the product modeling has been created in the family of solid modeling, we can use the first method to avoid reconstructing. After selecting elements, creating elements, creating mesh and checking modeling, we can create the finite element model used to perform plastics analysis.In this design, it is difficulty to decide where to set the gate. we can see that the pedal is slender. According to common concepts, the gate should be set in the middle of product. Welding line would come into being if this design is adopted. Therefore mechanical strength of product will be reduced. In practice using, the middle of product would bear heavy force, so it is not safety to set the gate in the middle of product. Finally we set the gate at the top of product to ensure the mechanical functions of product. In this design the fluid orientation would be consistent in the molding, and the mechanical function could be ensured, but the temperature of tip fluid will drop much more because of the long route of flowing, the fluidity of fluid becomes bad. It is necessary to raise the pressure of entrance to fill the impression, but the raising is limited in certain range, so it is possible that the impression could not be filled fully. When we simulated the process of injection, the initial result was always unreasonable that the pressures of impression exceed that of injecting jet supplying. after analyzing, we modified the injection parameters. The temperature of molding and plastics fluid are raised so that the fluidity of fluid became good. Though the correcting, the results are very satisfied. The filling time is shown is Fig.3. we can see that the filling time is 4.81 second at which is the furthest from the gate. The pressure and temperature of analysis results are also in normal range. In actual molding, we adopted corresponding steps according to the analysis results, so the qualified products were produced.DEAS GNC is a new kind of NC programming tool based on graphic. GNC system has the function of creating and operating of complicated surface elements. We could also use the method as same as that is used in plastics analysis, namely, the geometry model was gotten from 第 5 页the family of solid geometry modeling. Thereafter we use a set of describing instructions to define the machining process and parameter, such as cutting tool, manufacturing orientation and step, etc. the system would display the manufacturing process. At the same time the cutter location (CL) file comes into being which includes all manufacturing information but cannot be discriminated by NC machine directly, so the post-process is necessary. The post-process of GNC is different from that of normal. Normal post-process user the special principle. At present, with the rapid developing of NC technology, the number of NC system become more and more. It couldnt meet the present needs that post-process is only consistent to special machines. GNC system uses the common principle. It supplies a functional tooltext macro processor (TMP) with which user can program post-process procedure suit for all kinds of machine easily. According to the specialty of manufacturing molding and the FANUC 11system that we own, we programmed the post-process procedure of three axes that is used to operate the standard cutting location file. The result is the ISO machining codes which can be directly fed into the control computer of CNC machines, and the effect of actual machining is very good.3. conclusions(1) the integration of CAD/CAM/CAE changes the traditional production of plastics molding. User can modify and optimize the product, molding and manufacturing at the aid of computer. The efficiency is improved and the error is cut.(2) by adopting the technique of CAD/CAM/CAE, the period of design and manufacturing of molding is shorten dramatically. The cost is cut and the quality of product is improved.(3) I-DEAS software is a CAD/CAM/CAE software system including geometry modeling, plastics analysis and graphic numerical control whose function are strong and practical value is high.
