The idea of the developed method of die wear analysis: (a) 3D scanning—measurements of the die and the replication mass imprint, (b) result of a direct measurement of the die burdened with errors caused by the imperfection of the scanning techniques, (c) results of a measurement through scanning of the replication mass imprint in the die, (d) result of a measurement (scanning) showing the real surface state of a worn tool without errors obtained by way of superimposing a reversed replica image onto a CAD model.
