Volume Graphics supports all phases of casting, from part design and process simulation to inline inspection. Each version of VGSTUDIO MAX, our comprehensive software for computed tomography (CT) data, provides you with more tools for obtaining results quickly, easily, and with incredible accuracy—so that you can make the right decisions to meet the numerous and challenging demands on the quality of your products. Here are the main reasons why upgrading to our latest version 3.3 is a worthwhile investment for anyone manufacturing cast parts.
Many problems that influence casting quality lie in the casting process itself. During cooling, voids can form and cause porosity. Cooling effects can affect the component and lead to shrinkage, warpage, and cracks in the material. Often, it is not possible to avoid these casting defects completely—but they can be controlled to prevent them from occurring in locations critical to a part’s functionality. CT data provides a comprehensive view of the cast part due to its ability to accurately represent both surfaces and inner structures. In combination with VGSTUDIO MAX, CT provides the unique possibility of getting a full understanding of a part's quality.
When using version 3.3, you will immediately notice how much more responsive the application feels and how much faster some processes are conducted. These performance enhancements affect everyday tasks, such as opening very large .vgl files, importing projection images, rendering and navigation in 2D and 3D views, copying and pasting into the Scene Tree, and autosaving.
Easily identify porosity nests by calculating the locally averaged porosity and visualizing it as a color overlay in 2D and 3D views.
The locally averaged porosity can also be mapped onto an integration mesh. Porosity levels for each mesh cell can be exported as a .csv file for validation of casting simulations or for use in structural simulations.
The sphere method allows you to calculate the wall thickness for complex geometries. It is available in addition to the classic ray method.
Reportable bookmarks make creating reports of top-level objects and analyses in automation scenarios more flexible and highly reproducible. Bookmarks can now be referenced by volumes and other top-level objects, analyses, and measurement plans and are included in the .vgrf format, the associated reports on Microsoft Excel (requires Microsoft Excel), and reports in the .pdf format. Reportable bookmarks offer a combination of high flexibility—because arbitrary 2D and 3D views can be stored as bookmarks—and high reproducibility for automated setups, because bookmarks can be stored as templates that can be used in automated workflows.
With the new Optical Character Recognition (OCR), you can now read out text in CT scans, such as object identifiers, and store the recognized text in the meta information. This can be used in many functions, e.g., to detect tool cavity markers on CT scans of injection-molded or cast components and then choose the right reference object or analysis in VGinLINE jobs for automated inspection depending on the cavity. The recognized text also improves the traceability of results back to tool cavities by including the cavity markers in reports.
To centrally store CT results in quality management or statistical process control software, you can now export detailed results of dimensional measurements, position & form tolerancing, and the global results of analyses (nominal/actual comparison, wall thickness analysis, porosity/inclusion analysis, fiber composite material analysis) using the widely used Q-DAS data exchange format.
With just one click, you can now update a high number of analyses for an object, e.g., wall thickness, porosity/inclusion, and nominal/actual comparison, which is enormously time-saving.
