Abstract Hybrid manufacturing is a combination of additive (deposition) and subtractive (machining) manufacturing in a single machine tool. Such a system can be used for near net shape manufacturing and component repair using either similar or dissimilar materials. Integrated into a single system, transition between additive and subtractive manufacturing can occur immediately and be leveraged to generate large components by alternating between the processes. This investigation shows how the interleaved capabilities can reduce overall cycle time by up to 68 %, improve average relative elongation to failure by 71 %, and reduce the average relative porosity fraction by 83 % when compared to traditional additive manufactured components. Results from this investigation builds the foundation needed for hybrid manufacturing to be applicable towards the manufacture of large complex components such as nosecones and marine propulsors.

混合制造316L不锈钢的力学性能及显微组织

摘要 混合制造是在单一机床中结合增材（沉积）和减材（加工）制造。这种系统可用于使用相似或不同材料的近净成形制造和部件修复。集成到单个系统中，增材制造和减材制造之间的转换可以立即发生，并通过在过程之间交替来利用以生成大型组件。这项研究表明，与传统的增材制造部件相比，交错功能如何将总循环时间缩短多达 68%，将平均相对失效伸长率提高 71%，并将平均相对孔隙率降低 83%。
