WHY IS CT SCANNING IMPORTANT IN MANUFACTURING?
CT Scanning is progressively recognized as a promising solution for quality control. More and more industries are beginning to implement 3D Technology in their manufacturing process to quickly identify any voids or cracks, measure hard or impossible to see features that were either assumed or simply excluded. Clearly, analysis of assembly defects or actual prototype for production evaluation in complex or impossible to access geometry with the CT Data produced from a metrology grade CT Scanner. X2 Metrology can then generate a CAD-to-part comparison map, dimension the part or reverse engineer the part to suit our customer’s needs.
HOW ACCURATE IS A CT SCANNER VS. A LASER SCANNER?
Any data captured using 3D Scanners is not perfect. CT Scanners accuracy on small parts +/- 0.010mm and on large parts +/- 0.025mm. Handheld scanners sometimes referred as a portable CMM accuracy is between +/- 0.030 – 0.060mm. CT scanners are more accurate to laser scanners and handheld scanners are a faster turnaround compared to CT scanners.
WHICH INDUSTRIES USE CT SCANNERS?
Automotive, Aerospace, Telecommunication / Satellites, Energy, Consumer Goods / White Goods / Household Applications, Medical, Material Analysis, Electronics, Universities / Research, Global Manufacturing, Archeology, Castings, Die Cast, Mold, Plastics Personal Products Industry, Personal Electronics, Food Industry, Jewelry, Dental, Art Preservation, Archeology, Marine and Defense.
CAN I MEASURE VOIDS OR CRACKS?
Prior to metrology grade CT Scanners it would require that the part be cut in order to see internally for voids or cracks. CT Scanning can be used to find, measure and analyze voids inside plastic or metal components. Moulded plastics and metal casting components are more likely to have porosity because of cooling processes, shift between thick and thin walls and material properties. Resolution and Speed has improved tremendously and can uncover enclosed appearance and defects exposing this information in 3D without destroying the part. X2 Metrology NDT Lab scanner services.
CAN ANY MATERIAL BE CT SCANNED?
The new scanning approach offered by today’s metrology can inspect nearly any type of material with X-Rays going through, in any geometrical structure and compare it with an original CAD file. A casting, forging or machined component can be inspected with precise data points used to generate all types of photographic images. File outputs (STL,IGES) then compared with a design file, a physical model or actual prototype for production evaluation.
What does Non-Destructive Testing Mean?
A CT Scanning method that does not ruin or damage products or materials being tested. It uses a nondestructive approach to detect weariness effects, structural flaws, and other such defects. Measurement of complex, hard or impossible to reach features. For more information on different types Non-Destructive Testing (NDT), Non-Destructive Inspection (NDI), Non-Destructive Examination (NDE) or Non-Destructive Evaluation (NDE).
How is Optical Metrology different from CT Scanning?
Optical metrology is the science and technology regarding metrology with light. Such measurements can target properties such as some distance and optical metrology can be extremely accurate. Optical Metrology can be used in various ways to measure distances or displacements without physical contact. In fact, they allow for the most sensitive and precise length measurements, for extremely fast data capture and for the largest measurement ranges. Scans the direction of the distance measurement in two dimensions. This allows the acquisition of an image, or more precisely a depth profile of some object. For acquiring such depth profiles at a higher rate, there are sensor chips similar to CCDs (charge-coupled devices) with internal electronics to detect phase shifts, so that the distance for each pixel can be measured simultaneously. This allows for rapid three-dimensional imaging with very compact devices. The benefit of industrial CT computed tomography scanning is that internal geometry is also collected in three-dimensional without any damage to the part and optical metrology is not.
