Optimal strip layout of irregular shapes by die stamping them from metal sheet

Abstract

This article deals with optimal nesting problem when irregular shapes are cut from strip metal sheet by using die stamping method. The objective of the research is minimizing the waste of material or maximizing the number of shapes cutting from metal sheet. By generating some mathematical models and building up their algorithms, the software for solving problem dedicates to a number of industries for saving the time and minimizing the waste of material, and of course, increasing the productivity of manufacturing
