GOM Launches Metrology CT

Structured light and factory automation metrology company GOM introduced the market to its entry into the Computed Tomography field this week at the Control Exhibition in Stuttgart, Germany. It already offered to ability in its GOM Inspect software to import computer tomograph generated voxal point clouds in all common formats including *.vgi, *.vgl, *.pcr, *.exv, *.rek, for metrological analysis.

When it comes to complex components with internal structures, many measuring procedures and technologies reach their limits. GOM states it has developed a computer tomograph specifically designed to meet the metrological needs of industry. The GOM CT scans complex components in one measuring sequence and thus makes the entire part including internal structures available with component positioning performed automatically.

GOM CT technical specifications: 225-kV x-ray source | 3k detector | Measuring Volume: 240 mm x 400 mm | Photogrammetric Calibration | Temperature balancing | 5-axis kinematics.

GOM CT Project Manager Dr. Dominik Stahl met up with metrology news and explained the project’s mission.

Industrial CTs have been in use for years. Why is GOM’s system still an interesting alternative?

Increasingly complex parts, which are manufactured in additive procedures, for example, are pushing up the demands placed on measurement technology by industry. CTs for part inspection are already available on the market. However, these systems often do not meet the high metrological requirements. That is why we have used our experience in the field of industrial metrology to develop a CT that meets the demands of the market.

What makes the GOM CT stand out from other systems?

As a metrology CT, the GOM CT of course delivers high-precision and repeatable measuring data. Our system achieves complete surface meshes in maximum resolution with very small measuring volumes. In addition, measurement and evaluation are carried out in a simple workflow.

For which applications was this GOM CT system mainly developed?

The GOM CT scans transparent parts or very complex injection-molded components with internal structures that cannot be measured without a destructive method. Applications include first article inspection, tool release or the inspection of medical components.
The workflow in other systems often is complicated.

How was this solved with the GOM CT?

Working with the GOM CT is simple. Parts can be easily positioned, the scan itself is performed automatically. The data obtained is converted directly into a surface mesh, so that the evaluation is carried out as usual in the GOM Inspect software package. Both internal and external part geometries can be used for nominal-actual comparisons, shape and dimensional checks or reverse engineering.
