The use of computed tomography (CT scanning) for dimensional inspection is rapidly expanding as companies discover how this technology is the best solution for a wide range of dimensional inspection, flaw detection, and assembly verification applications.
Precisely measuring and validating parts made from low-density materials such as plastic can be tricky and time-consuming. For example, silicone parts readily bend and flex, leading to inaccuracies. Fixturing, the traditional solution to immobilize and align parts for measurement, is a lengthy process involving engineering, construction and validation of the custom fixture.
Computed tomography (CT) scanners are a popular choice for inspecting both the external and internal geometry of parts — finding inclusions, voids and flaws that could cause failure or underperformance.
