SGER/GOALI/Collaborative Research: Deformation Machining - A New Hybrid Process

探索性研究小额拨款(SGER)/产业界学术联系机会(GOALI)/合作研究项目的研究目标是验证一种新的混合制造工艺的可行性，该工艺具有使用三轴数控机床加工复杂三维薄壁零件的潜力。这种新的混合工艺将加工和单点渐进成形集成到一台数控机床中，称为变形加工。将这些工艺结合起来，将能够创建目前无法实现的新零件几何形状，并允许使用三轴机床制造一些现在需要5轴机床的复杂零件。这种新工艺可以灵活快速地制造轻型结构部件。这一工艺的潜在应用范围涵盖从航空航天到汽车等多个行业。航空航天应用包括舱壁、框架、支柱、纵梁和翼肋等零件。仅在航空航天行业，经常性的节省就将是可观的。节省的成本来自三个方面：降低设备成本、减轻部件重量和提高部件精度。这些节省完全是基于现有零件几何图形的复制来估算的。然而，预计会出现更大的好处，因为设计者将获得构思新结构的能力，这些结构只有利用变形加工的优势才能变得可行。

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.
