An important challenge to manufacturers is to increase product quality, which can be achieved through 100% part inspection.
Traditionally, X-ray Computed Tomography (CT) has been a valuable tool mainly used in research or prototyping labs to evaluate failures or spot defects; a proven engineering tool that was generally considered as too slow to be used on a production line.
Now however, recent advances in high-flux rotating targets for X-ray sources, coupled with easy automation of CT scanning and analysis techniques allow samples to be scanned, reconstructed and evaluated in time measured in minutes with micron accuracy. This opens the door to a broad range of automation inspection applications, varying from simple pass/fail inspection to semi-automated ct inspection and full in-line automated CT inspection with feedback to the production process.
By communicating with production databases the CT system can automatically recognize the part to be inspected, and adjust all parameters accordingly, further removing possible operator error. Inspection results can be written back to the database for further analysis or to preserve data history.
