Method for determining an ideal appearance of coated surfaces of components such as car body parts

摘要

Method for determining an ideal appearance of the painted surface of components such as car body parts in the automatic determined in advance of the structure finishing lacquer surfaces of an adhesive from a starting material, such as steel finely sheet metal coil component to be produced as a function of the respective surface structure of the component in the individual stages (1_H–M_H and 1_L–N_L) a m - stepped component production process or of a downstream n - stepped component coated process, with the following, by means of control loops of the component production process and of the downstream component coated process steps to be carried out successively:– in a stage 0, the surface of the delivered steel finely sheet metal coils by means of a two-dimensionally be measured topography measuring system (t) measured topographically,– from the topography measuring values (w), by means of a the topography measuring system (t) is connected downstream of the process control computer (p) the classical roughness parameters (ra, rz, etc.) as well as surface roughness parameters (maximum open empty surfaces number, etc.) and, by means of this, the characteristic always possible to q_e of the used steel finely sheet metal coils with the number of rpc, and so forth,– the determined characteristic always (q_e) a the process computer (p) downstream first signal - comparator (sk₁) with the determined..
