Abstract:
A method useful in a process of making and/or maintaining a surface of a tool used to form a part:a) scanning the tool surface with an optical shape measurement camera to obtain a first set of electronic images from different views of the tool surface; b) processing the electronic images to develop a first set of data defining the three-dimensional shape of the tool surface; c) scanning the part surface of a part made by the tool with an optical shape measurement camera to obtain a second set of electronic images from different views of a surface of the part formed by the tool surface; d) processing the electronic images of the second set of images to develop a second set of data defining the three-dimensional shape of the part surface; e) providing a third set of data defining a master part shape of the part surface; and f) processing two selected sets of the three sets of data to develop a fourth set of data defining differences between the two selected sets of data.
