Oberkochen, Germany – October 24, 2007 — Carl Zeiss Industrial Metrology offers METROTOM® 1500, a powerful computer tomograph for industrial quality assurance. It provides access to the interior of workpieces that are inaccessible for contact and optical sensors. METROTOM is used to check the structure of materials and also measures exterior features. As with all 3D coordinate measuring machines, the operator can also take advantage of the numerous benefits of CAD-based ZEISS CALYPSO® measuring software which was adapted to meet the specific requirements of Metrotomography® from Carl Zeiss. The measuring results from CALYPSO enable continuous monitoring of development up to initial sampling. METROTOM 1500 also permits the generation of CAD models.
Metrotomography – computer tomographic workpiece inspection
Metrotomography can be used for assembly checks and material inspections, as well as damage, porosity and defect analyses. Large plastic and aluminum parts up to 350 mm can be inspected using METROTOM.
The computer tomographic inspection of workpieces is very fast. CALYPSO measuring software provides support, for example, when comparing nominal geometries in areas where it had only been possible to conduct visual inspections. The results from CALYPSO can be used to continuously monitor development up to initial sampling. Tools, as well as casting and assembly procedures, can be modified during the development phase of a workpiece. The process start-up times become shorter; development costs lower. Operators directly benefit as they can work in a familiar evaluation environment when they use METROTOM and CALYPSO. Automatic, objective evaluation methods are now available in areas where previously only manual, subjective evaluations were possible.
Metrotomographic generation of CAD models
Using HOLOS®, for example, the METROTOM 1500 computer tomograph can generate a complete CAD data set of each "metrotomographed" workpiece. This can then be displayed in all standard formats, thus enabling generation of fast, highly accurate data during the development of the design. The ability to create entire data sets of complex interior structures that cannot be digitized or measured using traditional methods is essential.
Traceability of Measuring Results with METROTOM
METROTOM 1500 is calibrated using proven procedures with calibrated standards. With this procedure, Carl Zeiss guarantees the specified accuracy of the measuring result without additional contact or optical reference measurements. As a result, a key benefit of METROTOM 1500 – the omission of an additional measuring run with other sensors – is fully utilized. The results are traced to the linear standard of the PTB (German National Metrology Institute) using calibrated standards and standardized methods. Carl Zeiss has submitted a patent application for the procedure used to calibrate METROTOM 1500.
