9521494 Miller Ductile regime grinding is the term used to describe grinding high performance materials like ceramics, so that the material removal mechanism is primarily deformation, not brittle cracking with the attendant sub surface damage. This type of material removal has been studied and documented, particularly for grinding lenses. However, general adoption by industry requires innovative ways to improve productivity while minimizing surface damage. This research planning grant will investigate ways to improve material removal rates, and identify performance requirements for applications other than ceramics. Two ways to improve material removal rates will be investigated experimentally. The first will use optimized abrasive wheels with small grits for the small chips characteristic of ductile regime grinding, and large grits to prevent loading. The way to enhance material removal will use ultrasonic excitation to mechanically change the grit size. A literature review and industrial visits will be used to identify performance requirements for non-optics applications. Successful completion of this project will lead to higher productivity in processing ceramics suitable for a wider class of applications. This award will also encourage the diversity needed in the manufacturing research community. ***

小米勒9521494 延性范围磨削是用于描述磨削高性能材料（如陶瓷）的术语，因此材料去除机制主要是变形，而不是伴随着亚表面损伤的脆性开裂。 这种类型的材料去除已被研究和记录，特别是用于研磨镜片。 然而，工业的普遍采用需要创新的方法来提高生产率，同时最大限度地减少表面损伤。 这项研究计划拨款将调查提高材料去除率的方法，并确定陶瓷以外应用的性能要求。 将通过实验研究两种提高材料去除率的方法。 第一种方法将使用优化的小粒度砂轮，用于延性区域磨削的小切屑特性，并使用大粒度砂轮以防止加载。 提高材料去除的方法将使用超声波激励来机械地改变磨料尺寸。 文献综述和工业访问将用于确定非光学应用的性能要求。 该项目的成功完成将提高陶瓷加工的生产率，适用于更广泛的应用。 该奖项还将鼓励制造业研究界所需的多样性。 ***
