Due to the tremendous quality and efficiency benefits associated with the use of industrial computed tomography (CT) for non-destructive failure and structure analysis and 3D metrology for measurement of internal part geometries, demand for the technology is quickly growing. To meet this growing demand, GE Measurement & Control justlaunched its phoenix datos|x2.3 next-generation CT software, applicable for use withmost industrial CT systems offered by GE Measurement & Control’s Inspection Technologies division. The softwarecomes with new highlights like a specific production mode for fully automated CT data acquisition, reconstruction and evaluation and supports high precision 3D measurements following VDI 2630 guidelines.
The software with the new one-button-CT production mode automates the entire CT process chain from scan to final evaluation report. This new advancementallows 3D metrology and failure analysis to be performed significantly faster and more consistently. With the production-oriented CT workflow, the operator can easily identify a part with a barcode reader, place it on the rotation table, press the CT start button and verify CT evaluation results. System control functions such as detector calibration or tube conditioning run totally independent from operator influence in the background. The software also includes system performance monitoring procedures which follow ASTM 1695 guidelines. Minimizing operator time and influence and improving part throughput and evaluation result repeatability, helps raise productivity in industrial production. The software also introduces a new metrology package option for highly precise and reproducible 3D metrology. It offers reliable, precise 3D measurements for nominal/actual CAD comparison, wall thickness analysis and efficient tool correction tasks. In contrast to conventional tactile coordinatemeasurement techniques, a CT scan acquires all surfacepoints even of an complex object simultaneously. This includes all hidden features like undercuts, which are not accessibleusing other non-destructive measurement methods. The measurement accuracy refers to the VDI 2630 guideline for applying CT in dimensional measurement which was first implemented in GE’s phoenix v|tome|x m CT system.
Supported by datos|x 2.3 software, a specific metrology|edition of the versatile CT scanner, phoenix v|tome|x m is now GE’s first industrial CT system to feature precision CT measurements. This edition includes temperature stabilization of the enclosure, a high power 300 kV/500W microfocus X-ray tube and the 4 megapixelshigh performance 400x400mm DXR digital detector. Additionally, it comes with a direct measurement system for all linear axes, test phantoms for validation and performance tests, and highly automated procedures for axis, system and voxel calibration. The metrology edition can be verified to an accuracy specification of 4+L/100μm referring to VDI 2630–1.3 guideline.Due in part to faster scanning,reconstruction and evaluation capabilities, examination reports can be automatically generatedin less than one hour, ensuring a high sample throughput. The customers now benefit from both advantages of industrial CT, combining 3D metrology and inspection within one CT scan,” highlights Dr. Oliver Brunke, lead CT product manager for the product line. “By providing more efficient 3D production process control, GE brings CT solutions from the R&D and quality labs directly to the production floor helping to increase quality as well as productivity.”
