Yxlon sets focus on metrology at Control 2017


Yxlon’s stand at this year’s Control exhibition, which took place 9-12 May in Stuttgart, revolved primarily around the topic of metrology using computed tomography (CT).

The advantage of CT systems in measurement technology is that, unlike optical and tactile methods, inner structures and material boundary surfaces can be measured with extreme precision. The fully-automatic, standard-compliant acceptance test procedure in accordance with the German VDI/VDE 2630-1.3 guideline ensures system traceability: measurements that deviate from the calibrated Yxlon standard test specimen are automatically determined and documented.

Alongside the system component status, the readiness to measure is signalled on the system health monitor and colour-highlighted. The precision mechanics used, involving a granite-based manipulator, longitudinal scales and angle measurement module on the turntable, all fulfil the highest demands placed on accuracy and precision.

Temperature stabilisation within the CT system inspection envelope has been optimised for metrological assignment, too: the cooler is located outside the cabinet and can be relocated to a separate room when the need arises. The temperature range for Class 3 measuring rooms is reached inside the inspection envelope, thus minimising the influence of material expansion.

In addition to further enhancements of the graphical user interface for touch-screen operation, the convenient and very rapidly-executable ‘one-slice reconstruction’ is a major gain. It allows corrections and settings made on one singly-reconstructed slice to be checked and optimised. Afterwards, the complete dataset, including extremely accurate surfaces, offers unlimited options for measurement due to the fully captured, nearly infinite measurement point density. Additional software packages are supported to such a degree that the 3D volumetric image is automatically loaded following the CT scan and a measurement ‘macro’ can be performed.

The Yxlon MU2000-D, with its own CT option, was also featured on Yxlon’s stand at the trade fair. Successful on the market since 1997, 600 of these universal X-ray systems have been sold. The system has been continuously upgraded over the years and includes the latest developments in the fields of radiographic, radioscopic and CT technology, which have consequently maintained their state-of-the-art status. The system’s new features and options were presented at Control 2017, along with those of the Yxlon Cheetah, the microfocus system primarily used in the electronics sector.
