| Abstract Scope |
A multi-robot wire-fed directed energy deposition (DED) system can exceed the production rate seen in a standard single wire-fed DED robot. Multiple robots can deposit material simultaneously and collaborate with each other to effectively produce a large-scaled additive part. This, however, introduces the challenge of proper toolpath assignment for each robot to ensure that the robots would not interfere with each other. Pre-processed toolpaths, dynamic toolpath assignment, and region-of-interest (ROI) can eliminate this challenge. However, this can still result in long idle times for most robots solely based on their toolpath start points. In this work, a dynamic start point modification algorithm was developed to improve the utilization of the robots. A case-study was conducted to compare production efficiencies with and without using this algorithm. |
