In 2006, the innovative project “Geometric model building with CNC technology” at Vienna University of Technology acquired an industrial 7-axis robot. The KRH60 KUKA Robot is used at the Faculty of Architecture as a cooperative effort of the Institute of Architectural Sciences/ IEMAR-Digital Architecture and Planning , the Institute of Art and Design/ Three-dimensional Design and Model Building and the Institute of Discrete Mathematics and Geometry.

This state of the art machine is primarily used for CNC Milling and offers numerous advantages : The non-linear, spherical workspace is comparatively big, undercuts are possible and complex surfaces can be approximated more efficiently. The utilization of its seven axes (six robot axes with an additional turntable) enables the use of entirely new milling processes in architecure like freeform flank milling, which is physically impossible with a three axis milling machine.

Our research focuses on the innovative use of CNC-Technologies, the implementation of parametric design to production and the exact consideration of geometric properties.
