Abstract Scope |
It’s known that computer aided manufacturing (CAM) techniques for additive manufacturing (AM) influence material properties of the resulting component. However, CAM strategies used today have existed for decades without improvement. This research investigates the use of a novel toolpath strategy to generate discontinuity-free, axisymmetric components by AM. This strategy, termed additive turning, leverages CAM technology for turning strategies, where the component rotates around a stationary cutting tool. The additive turning strategy allows for entire components to be manufactured in one continuous deposition. This results in reduced cycle-time, improved material usage efficiency, decreased time to steady state temperature, and lower manufacturing costs compared to conventional AM strategies. Furthermore, additive turning can produce over 99% dense components, lesser variation and anisotropy in hardness, and low variation in elongation. The research highlights that specific CAM strategies can be deployed for AM to improve process efficiency, or to enable localized control over part performance. |
