Abstract

A method generates a nesting plan for controlling a cutting process of a flatbed machine tool for cutting workpieces from a material sheet. The nesting plan includes an overlap-free arrangement of sub-spaces corresponding to the workpieces in a two-dimensional planning space as well as a spatial arrangement of predetermined supported spaces. After each new insertion of a sub-space during nesting, a packing density evaluation and at least one evaluation incorporating the position data of the respective initial position of the newly inserted sub-space in a local search space are performed.
