Neutron computed tomography (nCT) is gaining commercial acceptance, while standard 2D neutron radiography (N-ray) has been in use for nearly 100 years. Neutrons interact differently within the atomic structure compared to X-rays, providing insight into the internal structure of a part.

In manufacturing, precision, accuracy, and efficiency are crucial. Traditional metrology methods ensure quality control, but industrial CT scanning is revolutionizing inspection and quality assurance.

Following the automation of manufacturing processes in industry, the fourth industrial revolution is addressing digital connectivity and communication between manufacturing, but also quality assurance systems, i.e., NDT or NDE systems.

With the advancements of many manufacturing processes, computed tomography (CT) and digital radiography (DR) are continuing to expand into new sectors of nearly all industries. Historically, these nondestructive testing (NDT) methods were primarily used for inspection of critical components, however, we are seeing an increasing number of companies extensively applying these technologies beyond just inspection work.

Many components and assemblies have internal features that are difficult to inspect, none more so than additively manufactured parts. Conventional quality control requires samples to be sectioned and subsequently scrapped.

I often hear, “How accurate can this be measured using CT?” For CT accuracy and precision should be considered together. For accuracy versus precision, picture a target.

Are you a manufacturer researching ways to improve and increase productivity, as your cast parts become more complex?

Over the last couple of years, numerous articles have been published by OEM equipment providers on the uses and benefits of industrial CT scanning for manufactured parts.

Virtually every manufacturer must perform some kind of testing or inspection to ensure their products meet their own internal quality standards, governmental requirements or the standards their customers set.

Industrial computed tomography has been a buzz-worthy technology for several years, and NDT experts know it’s a valuable tool for inspecting the complex internal geometries of 3D-printed parts, or for finding porosity in both additively and traditionally manufactured parts.
