Abstract Scope |
Large Scale Additive Manufacturing of Metals (LSAMM) has gained traction in the ship-building industry for manufacturing propellers and other high mix, low volume parts. As a part of a National Shipbuilding Research Program (NSRP) project, an advanced robotic gantry DED AM system was developed and integrated that contained two different power sources for WAAM, PushCorp 5hp Spindle for subtractive processes, and a variety of sensors for monitoring and scanning during builds. Initial work on this project centered around depositing a high-skew propeller blade out of stainless steel. A digital twin was developed in PowerMill where offline robot toolpath planning was completed for the builds on this system. A Single Sided Integrated Build Platform (SS-IBP) Scaled Quality Build (SQB) was built on the system to inform deposited material properties. Future works are moving to “lights-out” capabilities for this system by integrating thermal management, automated torch maintenance, and hybrid manufacturing capabilities. |
