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.

The imaging/inspection method has greatly evolved since its inception and it is now used in many industries for diverse types of product. 

Additive manufacturing (AM) technologies continuously blaze the trail of what’s possible for part design. As such, reliably and accurately inspecting the latest parts has become increasingly complex.

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.

Every business or service today has some form of quality control or quality assurance. With such high market competition, quality has become the market differentiator for almost all products and services.

Coordinate measuring machines (CMMs), vision systems, the trusty micrometer—no manufacturer would argue the importance of traditional dimensional metrology equipment, but the fact remains that the tried and true sometimes comes up lacking.

In the automotive industry, quality control/assurance has often focused on the physical testing and evaluation of raw materials and finished products. From a safety perspective, it is imperative that the strength of these materials and products meets established standards. Tensile, compression, bending and hardness tests are used for these evaluations.
