What technical operation problems exist in sandblasting process
Currently, the three-dimensional design software for common mold standard parts typically employs a component family-based library management system. The file structure involves a solid model file combined with an Excel spreadsheet, which acts as the "parent file" of the component family. Each row in the spreadsheet contains specific size parameters that can be used to generate read-only files for particular specifications—these are referred to as "subfiles" within the family.
This approach leverages the parametric capabilities of 3D design software. By integrating Excel directly into the design process, various specifications and dimensions of standard components are organized into a table. The data is then exchanged between the 3D software and Excel through an interface, allowing the generation of a standard part file based on the required specification. This method is straightforward, practical, and aligns well with traditional design workflows, making it particularly suitable for small and medium-sized enterprises (SMEs).
Another approach involves secondary development, where a dedicated standard parts library is created using the software's API or open interface, such as UG's OPEN/API. This type of library often features a user-friendly interface and can be integrated into the software as a tool button. However, this method usually requires programming skills in high-level languages like C++. Most mold designers lack these skills and must rely on professional software developers to implement it.
Furthermore, the libraries developed through secondary development are often fully encapsulated. If any issues arise, the source code needs to be modified, which is not feasible for most mold designers. As a result, despite significant investments by many large companies in developing their own standard part libraries, the overall effectiveness and usability have often fallen short of expectations.
In summary, while both methods have their advantages, the Excel-based approach remains more accessible and practical for everyday use, especially in smaller design environments. It allows for greater flexibility and easier troubleshooting without requiring advanced programming knowledge. On the other hand, the secondary development route, though powerful, is more complex and less accessible to the average designer.
