Computer Aided Material Estimation for Leather and Synthetic Products, Based on Parts Compact Drawing Method

Correct material consumption estimation, from the design stage of a leather or synthetic product, is an important issue, because material costs represent a significant percentage from the sale price of that product (footwear, bags, automotive, etc.). Over time, the specific theory for these products, and also the manufacture sites for leather and synthetic products, suggested different methods for material consumption estimation. This paper presents algorithmics for one material estimation method, based on compact drawing of article parts, in two variants, the bounding rectangle and the squares network. Research focusing in this direction is justified by the fact that this method has a wide application in the industry, but often the provided results do not match real values, with hard to tolerate deviations. By developing an algorithm, we aimed to control parameters specific to this method, in order to enlarge and control the estimation domain for this method.
