Abstract: A method includes obtaining an image of the contour of the coupon in its initial state and the position of the defects, after repositioning the coupon in a state ready for cutting; obtaining a new image of the contour of the coupon; superimposing the two images; determining a rotation value to be applied to one of the two contours to minimize the total surface area of the zones that do not overlap; applying the rotation value to the position of each defect in the image of the coupon in its initial state to pre-position each defect; determining geometric transformations to locally minimize the surface area of the zones of the two contours that do not intersect; and applying to the position of each pre-positioned defect based on its position inside the contour to accurately reposition it inside the image of the coupon in its state ready for cutting.

Abstract: A method is provided for automatically modifying the cutting paths for parts to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths. The cutting paths are associated with each part being defined by a succession of cutting segments forming a polygon. Two cutting segments are identified and belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied. Two cutting segments are verified for being situated facing each other, and that no other cutting segments lie between the two cutting segments. A common cutting path for the two cutting segments is computed, and a common cutting path is connected to the cutting paths of the two parts for cutting out to obtain modified cutting paths for the two parts for cutting out.
