CT Dimensional Inspections

Dimensional Inspection determines the geometric characteristics of components, machined parts, sub-assemblies, and products to verify they conform with design specifications. ATS utilizes an innovative technology to ensure products fall within geometric tolerances outlined in their design specifications for functionality, reliability, or product development: Computed Tomography (CT) dimensional inspections. CT dimensional inspections scan parts by collating a series of X-rays into a 3D figure composed entirely of cross-sectional images that our technicians can use to conduct dimensional measurements of both internal and external features. CT offers advantages over conventional and optical coordinate measuring machines (CMMs) as a non-contact nondestructive measurement technology.

CT Dimensional Inspections Applications

Computed tomography allows our specialists to verify the precise dimensions of a part by scanning it to generate a 3D model. Comparing these measurements to its CAD drawing enables them to perform a quantitative assessment of any deviations from the subject’s design. Finding these defects early provides clients the flexibility to modify their production processes to ensure consistency across their production lines. The x-ray facet of CT allows us to verify whether internal features conform to design tolerances without harming the subject —another advantage over tactile measuring methods like CMM.

ATS’ CT dimensional inspections provide quantitative analysis that interprets product evaluation with varying stages of life cycle, development, and manufacturing processes. Furthermore, dimensional inspections serve an imperative quality control purpose when applied to new manufacturing processes and technologies. CT benefits new technologies in industrial production, such as Additive Manufacturing — which can yield complex parts and components that may have inaccessible internal characteristics.

CT also has reverse engineering applications, such as for duplicating parts with no original design specifications or CAD files. In addition to dimensional inspections, CT is capable of thickness measurements, flaw detection, porosity characterization, failure analysis, finite element analysis (FEA), and more.
