Free Form Surfaces

In diesem Beitrag wird ein neuer Ansatz zum Erstellen von Maschinenprogrammen zur mikrofrästechnischen Oberflächenstrukturierung vorgestellt und die Anwendung der Prozesskette für ein komplexes, industrielles Verzahnungswerkzeug beschrieben. Durch die Reduzierung des Berechnungsaufwandes in der CAD/CAM (Computer-aided Design & Manufacturing)-Umgebung können die Limitierungen konventioneller Softwarelösungen umgangen und Bearbeitungsprogramme für komplexe Strukturierungsaufgaben effizient erstellt werden.   A new method for generating machine programs for micromilling surface structuring is presented, and the application of the process chain to a complex, industrial gearing die is described. By reducing the computational effort in the CAD/CAM (Computer-aided Design & Manufacturing) environment, the problems of conventional software solutions can be avoided and complex machining programs can be created.

Interactive Virtual Environment

Abstract The current trends towards fully integrated digital design processes depend on the use of physical mockups. Free Form Fabrication extracts data from Computer Aided Design software and transforms them into a tangible reality. Virtual Reality (VR) provides a remarkable complement to these techniques. The system presented responds to the needs to ensure accurate data and quick prototyping by providing visualization and edition of Computer Aided Design files in a Virtual Environment. This paper expands on the use of VR to virtually prototype artifacts represented by .STL files. It describes different techniques to interact with the object in the VE. Besides manipulating the object, various methods to display the triangles generated by tessellation are detailed and ways to correct the files are illustrated.
