In this paper we show a new automated measuring system based on a fast optical co-ordinate acquisition device that performs the calculation of all the parameters characterizing the strain of an industrial piece. These results are obtained with high accuracy and in real time. An application of this improved system is illustrated and the whole measuring procedure is described in the following steps: grid marking on the metal sheet, stamping, co-ordinate acquisition, calculation of the strain parameters and their visualizaiton.
In this paper a new automatic strain analyzer system for sheet metal stamped parts is presented. This device is based on an optic 3D scanner working with structure white light, that performs measurements with high speed and accuracy. This new device can be a very useful tool in manufacturing industry.
