The paper concerns the possibility of the use of modern non-contact measurement techniques in a die forges, like application a measuring arms with integrated linear scanners to analyze wear of forging instrumentation. In particular, to assess the progress of tool wear forging - punch used in the second forging operation of the forging type cover. The presented detailed analysis examines the possibility of using 3D reverse engineering techniques for direct quality control and changes in surface layer geometry of the forging tools, based on the measurement of geometry changes for cyclically collected forgings. The research was divided into two phases. The first step was to analyse tool wear based on direct scanning of their surfaces, then develop a wear-loss curve of the geometric material. In the second step, a selected area of cyclic retrieved forgings from the forging process was scanned for use of an intermediate scanning method - reverse 3D scanning. On this basis, an analysis of the progressive material growth on the selected surface of forgings was made, which was also a loss of material on the punches. The performed analyses showed a good agreement of the geometrical properties of the surfaces (of the selected forgings representing the proceeding wear of the tool) and the geometrical defect of the working impression of the tool, based on the direct measurements during the production process. The obtained results allow for a fast analysis of the forging tool life with respect to the quality and the quantity (of material defect), which, in consequence, leads to significant economical savings.
