Abstract
A method for cutting out a panoply of parts. This cutting-out method includes producing data relating to points defining the contour of each part and to the position of each part in a Cartesian frame of reference of the panoply, grouping the parts together into at least one subset, each subset embodied by a box being considered as a single part; grouping the subsets into at least one set, each set embodied by a box being considered as a single part; establishing an order in which to cut out the parts from the subsets and sets defined respectively a cutting-out step in which the cutting-out tool moves from part to part in the cutting-out order.

A method of cutting out a panoply of parts, comprising:
- generating data defining a contour and position of each part as a set of cartesian coordinates defined as X along an x-axis and Y along a y-axis, of the panoply;
- iteratively performing the following steps until each part of the panoply of parts has been grouped in a subset:
- identifying an ungrouped principle part having a longest X axis dimension and a largest Y coordinate;
- defining a covering zone extending in a negative Y direction from the ungrouped principle part and extending between a smallest and largest X coordinate of the ungrouped principle part;
- and
- grouping other ungrouped parts disposed at least partially within the covering zone with the ungrouped principle part to form a subset when the other ungrouped parts have a predetermined amount of disposition within the covering zone specified by a covering index, B, having a value between 0 and 1;
- grouping subsets together having projection zones within a predetermined coincidence value when the predetermined coincidence value is specified by a superposition index, super-B, the subsets grouped together forming a set;
- establishing an order of cutting out the parts from the subsets and sets;
- and
- moving a cutting tool from part to part in accordance with the established order of cutting the parts.
