Smooth connection between CAD and CAM In order to optimally design complex molds and tools and to perform numerical control programming, it is very beneficial to integrate CAD and CAM directly. In recent years, the number of software packages used in this industry has increased significantly. The integration of Pro/Engineer (software products from PTC in the US) with Open Mind's CAM-Systems Hypermill is one of these packages. The integration of the CAM system into the Pro/Engineer-user interface provides a distinct advantage, which allows the entire process from design through simulation to simulation to work in a unified data model. Hypermill includes the use of a smart Feature-Technology, which facilitates the transfer and further processing of geometric information from the CAD system for CNC programming, thereby significantly reducing programming time. Feature can assign complex processing sequences in the form of process macros, notably the dual association between CAD models and Features in CAM systems, as well as numerous classification and filtering functions. Another CAM supplier like Sescoi in Japan has enhanced its software capabilities by linking CAD functions to CNC programming systems. WorkNC-CAD is an integral part of WorkNC as a whole, but it can also be used as a CAD system for tool and mold manufacturing alone. Increasingly intelligent systems accelerate engineering There are several reasons to support such insights. On the one hand, Features are becoming more intelligent. Features is a kind of knowledge at this time, and it can be used in different environments. A good example is the new Features, which Dassault has loaded into the Catia V5 software. Since Hypermill version 9.5, Open Mind has linked Feature-Technology and macros to a database for knowledge management: these processing strategies and tool information for individual features assigned by users can be stored as macros in the database, and Calls can be made when similar tasks are encountered in the future. The so-called Wizard-Technology also brings significant time savings. This software is an expert software that is directly loaded into the CAD system, for example, can significantly speed up the design of the die-casting mold. In this regard, an example is Delcam. The company's PS-Moldmaker, through the application of PS-Moldmaker in the design, can significantly improve the design efficiency compared with the conventional design, users estimate that it can save 20% to 50% of the time, as shown in Figure 2. As a knowledge-based system, this software becomes an innovative hybrid software system with automation and flexibility to speed up the design process and enable structural changes to be effectively implemented. PS-Moldmaker uses the other programs of the Delcam CAD/CAM software package to assemble Power Solutions. By introducing Power-Features software, it is also possible to work with a strong judgment: a parameterized component can automatically react, if the component is placed in a certain position in the component, and can be connected to the connected component Add the necessary mating signs. If the mold designer, for example, wants to use a locating pin to complete the assembly of the mold, the software automatically makes a corresponding mark on the stencil on which the pin is positioned. In addition, the software automatically determines tolerances between different components. On the blank, the holes are placed in a precise fit to a certain position and an allowable spacing is added to the holes on all of the plates on which the pins are placed. If the position of the pin is to be changed, all associated holes will also change. PS-Moldmaker's virtual intelligence has other advantages: the software will recommend the appropriate size of the component through Power-Features, and recommend the standard size, if the standard parts are available in the important component suppliers in the unified component catalog. if. If the user wants to make a design change, the software will recommend replacing it with the closest size. It is just the component size of a simple digital change. Therefore, in most cases it is not necessary to use non-standard components that are expensive, manufactured and time-consuming.

Development trend of mold manufacturing CAD/CAM software (Figure)
Germany's mold and tool manufacturing industry is aware of the strong competition that comes not only from the former Eastern European Union countries, but also from the Far East, especially from China. In order to withstand this competition, many companies have begun to adopt multiple approaches, such as high automation, which is one of these ways. Germany's Color Metall has implemented two-shift unmanned operation and is able to supply on time and at market prices. Other accomplished mold and tool manufacturers have expanded their supply offerings, and these companies have begun to do their work in product design, and finally assembled many parts into complete products or assembled into parts. Other companies are also involved in parts production. Regardless of which of the above methods is chosen, a self-contained, highly efficient production process is always essential. For many companies, there is still much work to be done in this area until now. In this regard, further important development trends are...
