jailcd2020128: Digital Robotic Double-Curved Hot-Wire Cutting

Abstract

With the continuously development of nonlinear design in construction industry, nonlinear buildings are more inclined to be designed and constructed. However, due to the limitations of the current construction approaches, the level of construction that can be achieved is extremely limited. Consequently, complex and costly processes have inspired the rise of the building customization industry. Generally considered, in the existing spatial wire cutting (SWC) technology, multiple robots could be used for cooperative operation, while having less flexibility, convenience than single robot operation. Therefore, different kinds of errors, and even deformation in three-dimensional space can be occurred when fitting. Thus, new methods need to be carried out. In the preliminary experiments, we ran many tests with different voltages and wire sizes to acquire more suitable cutting conditions. Then to reduce large errors caused by cooperative operation, the following part studies on the cutting approach of complex double-curved surface operated by a single robot and reduces certain errors at the meanwhile. Every single sweeping curve will be fitted on the double-curved surface they should be lain in, with more preciseness than the cooperation of two robot arms, and experimented with cutting of polystyrene foam examples.
