CAD interface for automatic robot welding programming

Industrial robots play an important role in industry, due to their exibility. Many applications (almost all that require human intervention) may be performed with advantages by robots. Nevertheless, set-up operations, necessary when changing production models, are still tricky and time-consuming. It is common to have detailed data of working pieces in computer aided design (CAD) Žles, resulting from product design and project. This information is not used satisfactorily, or even not used at all, for robot programming. In this paper, we propose a solution capable of extracting robot motion information from the CAD data.
