Method and system for automatic cutting of pieces in a flexible material packaged in roll form

A method for automatically cutting parts in a flexible material packaged in the form of a roll, comprising the successive steps of:

• a) preparing an initial placement for a list of parts to be cut out in the flexible material;
• b) spreading at least one layer of flexible material on a cutting table;
• c) starting the automatic cutting of the parts in the material spread on the cutting table according to the initial placement;
• d) during the cutting of the initial placement, upon receipt of a triggering event for which the placement of at least one of the parts is no longer adapted to the cutting environment or for which the list of the parts of the initial placement needs to be modified, preparing a list of parts to be maintained;
• and
• e) automatically preparing a new placement taking into account the position of the parts to be maintained and calculating new positions for all or part of the other parts—called parts to be repositioned—without taking into account their positions in the initial placement.
