Abstract
Subtractive manufacturing technologies, such as 3-axis CNC milling, add a useful tool to the digital manufacturing arsenal. However, each milling pass using such machines can only carve a single height-field surface, defined with respect to the machine tray, limiting the set of geometries that may be produced with this technique. In this talk, I would like to present two methods which enable the fabrication of simplified or decomposed geometries using subtractive technologies. The first method aims to obtain, starting from a given model, a simplified shape that can be easily unfolded. The second method enables fabrication of general 3D shapes using 3-axis CNC milling methodology by providing a novel robust algorithm for decomposing general 3D geometries into a small set of overlap-free height-field blocks.
