Page 1 of 5 TopoCAMcmm Optical - 3D Coordinate measuring technique | | Modern manufacturing technologies increasingly allow the free form design of components in which regular shapes no longer need to be taken into consideration. The resulting so-called freeform parts or freeform surfaces can thus only be described by the CAD model.As a consequence of this, a sufficiently high number of measuring points is required in order to describe and compare such free shapes. The meanwhile, termed classical coordinate measuring technique based on tactile scanning, meats its limitations very quickly when used for the processing of free forms. Due to the applied principle of measuring data acquisition, only single measuring points or designated positions can be captured. In practice, even intended standard geometries are often unfathomable free shapes that have to be recognised and measured by the metrological equipment! With our new approach of providing a CNC-driven 3D coordinate measuring instrument with area-based measurement, we are opening up a new dimension in 3D coordinate metrology and leave no geometric surface defect on your component undiscovered. Intelligible, and easily interpretable graphical 3D evaluation protocols with colour coded representations allow a selective elimination of possible quality faults on your components. | 3D-CNC measurement of components | | | 
| | With a maximum geometric information density enabled by the area-based measuring techniqueof stripe projection with highest measurement accuracy you are in a better position to checkand increase your product quality automated. By an automatic 3D raster scan an acquisition of the 3D geometry without previous accurate knowledge of the object to be measured is obtained. As result of the raster scan a 3D dataset with several million measured points is generated, quickly and defined comparable to a CAD dataset or reference data. | | | | | | Optical 3D coordinate measuring machine TopoCAM
