A method for producing or assembling a product which includes at least two components, for example a motor vehicle or a motor vehicle module, by at least two fixing parts. The first fixing part is formed as a female part and the second fixing part is formed as a male part. The components disposed at a processing station and the first fixing part are measured by a measuring device, for example by a stationary camera or a camera fastened on a first or a second manipulator or photogrammetry bar having three cameras, and a deviation from a target geometry or target position is determined, and a corrected target position of the second fixing part is calculated on the basis of the determined deviation, such that the second fixing part is joined together with the first fixing part by the first manipulator and the product is thus produced.

The object of the invention is a procedure for vulcanization which includes a determination of the vulcanization coefficient of an elastomeric workpiece, and an apparatus for the application of the procedure. Prior art is the measurement of the rapture strength or the penetration depth of a needle and the calculation of the vulcanization coefficient from the measured value. The disadvantage is its restriction to the application for time-consuming measurements of samples taken at not too short intervals. Series testing is excluded. The task consists in defining a procedure which leaves the workpiece undestroyed and where the measuring time is so short that it can be applied in series; and in the development of the appropriate apparatus. The solution is a procedure where the workpiece to be tested is compressed and suddenly relieved, whereupon the recovery distance is followed and an asymptotic value determined from it, from which, after obtaining the result of the determination of the known vulcanization coefficient of at least two comparison specimens, the vulcanization coefficient of the workpiece can be determined graphically or by way of calculation; as well as an apparatus with a laser element for spreading, collimating and focussing a parallel beam of light, the light spot of which on the specimen surface is examined optoelectronically and maintained constant by way of the readjustment of the objective, while at the same time the recovery distance is measured; in particular using a workpiece adjusting device 10, a compressing device 12, a distance/time measuring device 14, and an electronic evaluation unit 16 with an electronic application system 18.
