At Germanys KRAMSKI Group GOM’s ATOS Capsule system guarantees a high level of detail in the quality assurance of electronic components and accelerates Mold Tool try-out.
For its development process of sophisticated stamped and injection-molded parts, the technology company searched for an imaging technique that provides more than isolated 3D data. Following an in-depth bench-marking process, KRAMSKI opted for an optical measuring system from GOM to complement its tactile measuring room in order to handle complex parts more efficiently in the long run.
It is the system’s detail level and usability that convinced KRAMSKI to invest in the optical precision measuring machine. The fact that hardware and software come from a single source was another convincing aspect of the ATOS Capsule. In combination with a touch probe, the system can be used to measure difficult to access part areas.
“Compared to the coordinate measuring machines used to date, we can now save considerable amounts of time.
Particularly when measuring recursions, we get results very quickly, which can be used to evaluate whether the
optimization was successful. Furthermore, generating a measuring report has become very fast and easy,” explains
Mathias Schlegel. “It is very work-intensive to compare measuring results using figures, especially when there are multiple cavities. As such, the color representation of the deviations is a great help.” By implementing optical metrology, KRAMSKI aims to significantly accelerate the time between the try-out process and the final start of production. Faster results save a lot of time in individual recursion loops and, ideally, reduce the number of loops required in the medium to long term.”
KRAMSKI opted against a CT measuring device in favor of a fringe projection system. “Our requirements mainly entail external geometries. Insights into the part interior are hardly ever needed – considering the high costs for acquisition and maintenance, a CT system is not reasonable at the moment.”
“We looked at the components’ STL meshes and with the GOM system, they were simply clearer than with other manufacturers. It was possible to see a lot more details, such as the tiny numbers on the date stamp. The ATOS Capsule also provides an extremely satisfying result when measuring the surface of the plug box located deep in the MRR housing. Furthermore, GOM offers one of the few optical systems with an additional touch probe for areas which are difficult to see.”
