OPTIMIZATION OF ORIENTED NESTING LAYOUT ON RECTANGULAR MATERIAL SHEETS

Abstract

This article introduces research results on optimization of oriented nesting layout for pieces of  irregular shapes to be cut in rectangular  material sheets in order that number of cut pieces is maximized or material waste is minimized.  The optimized alternative is selected when material utilization coefficient is maximized with the requirement on strain, texture, fiber orientation of material sheet. This solution may be applied in some industries using sheet material and having requirement on orientation when cutting .
