Forming Analysis
Evaluate the forming states and surface strain levels of sheet metal parts after forming. GOM's ARGUS system clearly indicates whether the areas are over-deformed or still within a certain safety margin. This provides decisive information for optimizing forming processes, and validating simulations.
Easy and Fast
Unlike conventional methods for forming analysis, the ARGUS system provides an easy and fast measuring process and accurate forming results, even for complex and large parts.
Plan
Before preparing the part, the measuring areas need to be defined depending on the evaluation purpose, which may be the complete part or specific critical areas known from the production process or numerical simulation.
Prepare
Before forming, raw sheet metal blanks are marked using electro-chemical etching or laser marking with a hexagonal dot pattern.
Measure
After forming, the sheet metal part is recorded from different viewing angles by using the handheld ARGUS system. Small and large parts can be measured very fast with the same hardware.
Evaluate
Measuring results provide full-field information of the forming distributions on the parts, like major and minor strain, thickness reduction, forming limits, formability, etc.
ARGUS Technology
The certified handheld ARGUS camera is used to record deformed sheet metal parts from different viewing angles. In all acquired high-resolution images, 2D coordinates of all dots are mathematically derived and recalculated to 3D coordinates using photogrammetry principles, taking into account ray intersections, camera positions, and lens distortion. The main result is a fine 3D point cloud, consisting of thousands of points, which represent the 3D surface of the sheet metal part. By evaluating the relative distance between the points in combination with a local plane strain tensor computation, the strains over the entire surface are holistically determined.
