Feature-Based Volume Decomposition for Robotic Weld Deposition-Based Rapid Prototyping

Abstract:

A feature-based volume decomposition algorithm for robotic weld deposition-based rapid prototyping has been proposed to eliminate or reduce the use of support structure which decreases the building efficient. The algorithm decomposes the model volume into shapeable feature volume and un-shapeable feature volume firstly, according to the slope angle is greater or smaller than the critical slope angle. Un-shapeable feature volume is decomposed further into sub-volume until each sub-volume to be shapeable without support structure. Each feature volume or sub-volume may be assigned with different building orientation and building sequence in the process planning process. The model volume of a classical part was decomposed by this method to validate this method’s ability of eliminating the use of support structure.
