Method for modifying the cutting trajectory for parts intended to be cut from a flexible material

A method of automatically modifying the cutting paths for parts that are to be cut out from a flexible material by automatically moving a cutter tool along predetermined cutting paths, the cutting paths associated with each part being defined by a succession of cutting segments forming a polygon, the method comprising in succession:

• a step of identifying two cutting segments belonging to two different parts for cutting out in the material and for which a maximum distance condition between these cutting segments is satisfied;
• a step of verifying that the two previously-identified cutting segments are situated facing each other by reciprocal orthogonal projection of the cutting segments onto each other;
• a step of verifying that no other cutting segments lie between the two previously-identified cutting segments by computing intersections between the two parts for cutting out;
• a step of computing a common cutting path for the two previously-identified cutting segments;
• and
• a step of connecting the common cutting path to the cutting paths of the two parts for cutting out so as to obtain modified cutting paths for the two parts for cutting out.
