Patent ID: 8209050

Claim:
A method for classification of defects and running of grinding of lamination cylinders, comprising: a) identifying defect areas in a map illustrating a plurality of surface measurements of a cylinder by a1) subdividing said map into a plurality of cells each corresponding to a measurement sub-area of the surface of said cylinder; a2) classifying said plurality of cells in relation to a criticalness of a defect measured in a corresponding measurement sub-area; and a3) grouping a combination of cells of said plurality of cells associated with a same defect criticalness and arranged at a pre-established reciprocal distance, said pre-established reciprocal distance differing in relation to the defect criticalness associated with said cells; b) calculating, for each defect area identified, a plurality of parameters; c) identifying a type of defect associated with said defect areas identified, on the basis of the parameters calculated; d) determining an acceptability threshold of a specific defect for each type of defect identified; e) defining a corrective action for each defect area on the basis of a comparison between said acceptability threshold associated with the type of defect of said defect area, and a measurement of said plurality of surface measurements of the cylinder associated with said defect area; and f) determining grinding parameters on the basis of said surface measurements of said cylinder, when the corrective action defined in e) is a grinding operation to remove the defects.
