This paper describes an application of the cutting stock problem where great part of the complexity of the problem was actively addressed by mean of a definition of a suitable ontology. It deals with the realization of a series of concentric rings starting from a raw circular flange. The goal is to minimize the scrap and satisfy the customers demand, keeping into account all the constraints related to the coupling of rings and flanges. To reach the goal a combinatory optimization approach was employed. The mathematical model is solved by the LINGO software, an interactive tool for the solution of linear, quadratic and integer number programming problems.
