The research objective of this Small Grant for Exploratory Research (SGER)/Grant Opportunity for Academic Liaison with Industry (GOALI)/collaborative research project is to validate the feasibility of a novel hybrid manufacturing process which has the potential to generate complex three-dimensional thinsection parts using a three-axis CNC machine. The new hybrid process, which integrates machining and single point incremental forming into a single CNC machine tool setup, is called Deformation Machining. Combining these processes will enable new part geometries to be created that are not currently possible, and allow some complex parts now requiring a 5-axis machine tool to be fabricated using a 3-axis machine.This new process can enable the flexible and rapid fabrication of lightweight structural components. Potential applications of this process span industries from aerospace to automotive and beyond. Aerospace applications include parts such as bulkheads, frames, spars, stringers, and wingribs. In the aerospace industry alone recurring savings will be substantial. The savings come from three areas: reduced equipment costs, reduced component weight, and increased part accuracy. These savings have been estimated based purely on replication of existing part geometry. However, even greater benefit is expected to arise because designers will gain the ability to conceive new structures which only become feasible using the advantages of deformation machining.

这项针对探索性研究（SGER）的小赠款的研究目标/与工业联络（Goali）/协作研究项目的学术联络机会是验证新型混合制造过程的可行性，该过程有可能使用三轴CNC机器来产生复杂的三维三维零件。 新的混合过程将加工和单点增量形成整合到单个CNC机床设置中，称为变形加工。 结合这些过程将使创建新的零件几何形状，这些几何形状目前是不可能的，并且允许一些复杂的零件，现在需要使用3轴的机器制造5轴机床。此新过程可以使轻质结构组件的灵活且快速地制造。 该过程的潜在应用跨越了从航空航天到汽车及以后的行业。 航空航天应用包括隔板，框架，翼梁，纵梁和翼轮。 仅在航空航天行业中，储蓄将是可观的。 节省来自三个领域：降低设备成本，减轻组件的重量以及零件准确性的提高。 这些节省纯粹是基于现有零件几何形状的复制而估计的。 但是，预计会产生更大的收益，因为设计师将获得构想新结构的能力，这些结构只能使用变形加工的优势才能可行。
