Verification of Surface and Sharp-Edged Features
GOM has created a comprehensive solution and secure workflow for the sheet metal inspection process, enabling surface and sharp-edged features to be verified with one system. ATOS brings together high-quality measuring data and flexibility, so that it can be used not only in measuring rooms but also in press shops and raw production environments. Regardless of the object size, ATOS creates precise 3D coordinates and delivers complete measuring and inspection reports.
Complete Sheet Metal Part Inspection
The optical ATOS 3D digitizer captures the surface geometry of an entire component in form of a high-resolution point cloud. In addition, sharp-edged features can be measured with subpixel precision using algorithms developed especially for this purpose. This comprehensive concept makes it possible to verify the complete surface as well as hole patterns, trim and springback, tornado lines, gap and flush, and other typical sheet metal features. Thanks to the concept of Teaching by Doing and inspection planning based on CAD data in the GOM software, multiple part inspection can be automated as of the second part.
Automated Quality Control
Industrial production processes require automated measuring cells to enable higher throughput (more parts in less time, better planning) and higher repeatability for process safety. As a single-source provider of industrial measuring sensors and parametric inspection software, GOM’s automation team opens the way to standardized and centralized part inspection management with parametric and traceable inspection workflows.
Gauges and Fixtures
Rigid parts can be measured without fixtures using the contact-free ATOS digitizer, because the alignment of measured data to CAD data is controlled using RPS points in the GOM inspection software. If a sheet metal part is digitized when standing free and once installed, deformations can be measured and visualized. Variable alignment is possible due to data density and contributes to fast problem resolution during sheet metal assembly analysis. For the measurement of clamped sheet metal components, the contact-free measuring techniques enable an adaptive fixture concept, thus saving costly gauges. One simple clamping fixture can replace six measuring gauges, for example. Since it can be used in parallel for various parts, storage space and production time are saved.
Measure Parts in Free State through Virtual Clamping
With a new module that supplements the GOM software packages, sheet metal and injection-molded parts can be virtually clamped and thus measured without complex clamping devices. An innovative, FEM-based algorithm makes it possible to compute the clamped state of the part. This virtual clamping procedure is fully integrated into the GOM workflow. The measuring data obtained is exactly comparable with the results of the part when clamped physically.
The optical forming analysis system ARGUS supports the optimization of the sheet metal forming process considering the correct material selection and the optimization of tools. ARGUS provides full-field results with high local resolution for small and large components. Therefore, it is ideal for numerous sheet metal forming tasks like the detection of critical deformation areas, solving complex forming problems, optimization of forming processes, verification of tools and validation and optimization of numerical simulations. This is a decisive factor for competitiveness.
