GE introduces metrology package for highly efficient, extremely precise 3D metrology performed with Computed Tomography (CT)GE Inspection Technologies67, Wunstorf, Germany
Advanced industrial CT for 3D metrology and failure analysis
Wunstorf, Germany June 16, 2014 - Due to the enormous efficiency benefits, the use of industrial computed tomography (CT) for non-destructive failure and structure analysis, and 3D metrology (especially for measurement of internal part geometries) is growing fast. The phoenix datos|x 2.3 next-generation CT software from the Inspection Technologies business of GE Measurement & Control now features a new, one-button|CT feature that enables highly automated data acquisition and volume processing. This new advancement allows 3D metrology and failure analysis tasks to be performed significantly faster and consistently more repeatable.
Additionally, it comes with a new metrology package option for highly precise and reproducible 3D metrology, with a measurement accuracy referring to the VDI 2630 guideline for applying CT in dimensional measurement - first implemented in GE's phoenix v|tome|x m CT system, and first available in Europe. It offers reliable precision 3D measurements for nominal/actual CAD comparison, wall thickness analysis and efficient tool correction tasks.
By contrast with conventional tactile coordinate measurement techniques, a CT scan of an object acquires all surface points simultaneously. This includes all hidden features like undercuts which are not accessible (non-destructively) using other methods of measurement. Thanks to considerably faster scanning, reconstruction and evaluation possibilities, an examination report can be generated automatically in less than one hour.
GE's versatile 300 kV microfocus CT system phoenix v|tome|x m is now the first of GE's industrial CT system portfolio (made available in a specific metrology edition) to ensure extremely high precision and reliability of CT measurements. For example, this edition includes temperature stabilization of the enclosure, the high power 300 kV/500 W microfocus X-ray tube and the 4 megapixels high 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. Finally, for the phoenix v|tome|x m metrology edition an accuracy specification of 4+L/100 Î¼m referring to VDI 2630-1.3 guideline can be verified.
GE's industrial customers now benefit from both CT advantages, combining 3D metrology and inspection within one CT scan,â€ said Dr. Oliver Brunke, lead CT product manager for the GE Inspection Technologies business. "By providing more efficient 3D production process control, GE offers the system solutions to bring CT from the R&D and quality labs directly to the production floor."
