Reverse engineering is a technology that enables acceleration of data acquisition for CAD, CAM, CAE systems and thus greatly reduces the time of development, design and production of components. In general, reverse engineering technology can be considered as the conversion of analog data to digital data, which is further processed. Individual industries are still increasing their demands for accuracy, size, quality, and so, therefore the use of digitization is found in many manufacturing areas such as the automotive, aerospace, shipping, medicine, industrial design, design, and so on. The paper deals with the analysis of the prototype component of the agitator gearbox in the form of a rough and chip-machined casting. The inspection of the shape of the gearbox consisted in reading the reference CAD model, establishing the digitized shape with respect to this reference model, checking the dimensions and creating a color map of the variations at selected points.
