Abstract

In this paper we present a software tool that converts any two-dimensional black and white image into a CAD/CAM file in IGES format. It can be used to integrate topology optimization into CAD/CAM manufacturing systems, and that is indeed the main motivation of the work. The software is very versatile and allows to solve the interoperability issue between numeric is the IGES translator code lacking in most used numerical computation software packages.

The example chosen to illustrate our method along the paper corresponds to an optimized piezoelectric modal sensor/actuator following the ideas developed in Donoso and Bellido (2009). Notice that the layout is a pure 0-1 design. Black and white areas mean regions with opposite polarity, and that is the reason why it does not matter whether there are disconnected black areas or not.
