Abstract
A method and system for automatic cutting of defective parts in a fabric with a pattern repeating at a certain pitch, includes the steps of producing a theoretical layout of parts to be cut on a theoretical representation of the fabric whilst respecting layout constraints, spreading out at least one layer of fabric on a cutting table, checking at least one portion of the spread-out fabric to ascertain actual features, modifying the theoretical layout in order to generate an actual layout taking into account the actual features of the fabric, identifying in the actual layout, defective parts which will contain defects once cut in the fabric and which will need to be cut again, and automatically allocating each defective part to a new theoretical layout by adjusting the layout constraints associated with the defective parts according to the actual layout.
