| Abstract Scope |
X-ray computed Tomography (CT) scanning has been the method of choice to scan additively manufactured parts to identify internal features and defects without resorting to destructive exploratory methods. The X-ray CT process can take hours to days to yield a single reconstructed image which causes huge research bottlenecks. To remedy this shortcoming of X-ray physics, the authors propose a novel magnetic CT system which can scan parts in around 2 minutes. The system consists of a square wave driven magnetic coil and a hall effect sensor which are on either side of the part to be imaged. This project makes use of an Okuma Multus mill-turn machine to perform a 360-degree rotation of the part (clamped in the lathe chuck) and incrementally moves the hall effect sensor in a grid pattern to form each two-dimensional image. The authors will present their work on Magnetic CT for various materials and geometries. |
