This award supports fundamental research in understanding the relationship of tool wear evolution and vibrational stability to cutting mechanics when machining nickel-based superalloys, to provide knowledge needed to plan new approaches that can extend tool life and make behavior more consistent. Application of this research will help reduce costs and improve quality for high-value energy and aerospace systems, including defense applications. As such, this project promotes the progress of science, advances national prosperity and welfare, and helps secure national defense. Additionally, this work includes a plan for broadening participation of underrepresented and minority groups in scientific research by recruitment efforts through the National GEM consortium and Clemson's Women in Science and Engineering (WISE) programs. The objective of this research project is to decouple the variability in tool wear evolution models through a novel experimental procedure, and to relate wear and machining parameters to the plastic deformation layer (Machining Affected Zone, MAZ) depth in nickel-based superalloys. The derived models will be used to simulate stable, robust and minimum cost path plans. The approach to accomplishing this will be to model the process parameters' effect on wear and cutting forces, and the subsequent cumulative effect on the plastic deformation zone depth (i.e., MAZ) through a stochastic representation approach, whereby model parameters are represented as random-variable belief distributions. The knowledge generated will be applied to deriving robust tool paths for improving the process consistency and performance. If successful, the broader impacts of this work will include improved economy of machining for energy and aerospace manufacturers, and increased participation of underrepresented groups in scientific research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持基础研究，以了解加工镍基高温合金时刀具磨损演变和振动稳定性与切削力学的关系，以提供规划新方法所需的知识，从而延长刀具寿命并使行为更加一致。这项研究的应用将有助于降低高价值能源和航空航天系统的成本并提高质量，包括国防应用。因此，该项目促进科学进步，促进国家繁荣和福祉，并有助于确保国防。此外，这项工作还包括一项计划，通过国家 GEM 联盟和克莱姆森科学与工程女性 (WISE) 计划进行招募工作，扩大代表性不足和少数群体对科学研究的参与。 该研究项目的目标是通过新颖的实验程序解耦刀具磨损演化模型的可变性，并将磨损和加工参数与镍基高温合金中的塑性变形层（加工影响区，MAZ）深度联系起来。导出的模型将用于模拟稳定、稳健且成本最低的路径计划。实现这一目标的方法是通过随机表示方法对工艺参数对磨损和切削力的影响以及随后对塑性变形区深度（即 MAZ）的累积影响进行建模，其中模型参数表示为随机可变信念分布。生成的知识将应用于导出稳健的刀具路径，以提高工艺一致性和性能。如果成功，这项工作的更广泛影响将包括提高能源和航空航天制造商的加工经济性，以及增加代表性不足的群体对科学研究的参与。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力评估进行评估，被认为值得支持。优点和更广泛的影响审查标准。
