In recent years, productivity and competitiveness have played a major role in manufacturing. To improve these aspects, many companies use computer-aided inspection (CAI) technologies. Inspection of parts, using 3D scanning technologies, is one the most modern and competitive ways to ensure the quality control of products. This paper presents a study on the assessment of the machined parts’ dimensional accuracy. An Atos Core device for 3D scanning of the part was used. The Atos device allows a non-contact inspection of the part’s entire surface, generating a very dense  point cloud,  which stores, with great accuracy, all the details of the inspected object. The machined part is compared with its numerical model, obtained by computer-aided design (CAD). The accuracy of the machining was proven to be very good, and the inspection’s result proves that the dimensions of the piece fall within the tolerance limits. A complete inspection of the piece, using 3D scanning, guarantees a fast and accurate quality control, thus reducing the production times.
