The goal of this Grant Opportunity for Academic Liaison with Industry (GOALI)/Collaborative Research project is to develop environmentally benign minimum quantity lubrication grinding processes using nanofluids in place of conventional grinding fluids. Nanofluids are a new class of heat transfer and anti-wear fluids created by dispensing solid particles smaller than 40 nm in water or oil-based fluid carriers. The superior thermal and tribological properties of nanofluids make them particularly suitable for minimum quantity lubrication grinding. In this study, nanofluids using additions of copper, titanium borate, and carbon nanotube nanoparticles will be evaluated. A new fluid delivery system will be developed using an injector nozzle to accurately deliver a jet of high-pressure nanofluid mist to the grinding zone and a water mist spray to cool the workpiece and grinding wheel. A vacuum system will be tested to collect the near dry swarf in minimum quantity lubrication grinding.Grinding is recognized as an environmentally unfriendly manufacturing process. The selection and delivery of grinding fluids have traditionally been based upon the need to achieve tangible productivity and cost targets while often neglecting the seemingly less tangible environmental and safety hazards. If successful, this project can change this paradigm by developing "green" grinding processes based on the total cost approach. It can have a profound impact in industry to bring an awareness of the smart utilization of grinding fluid. This study can also advance the nanotechnology to environmentally benign manufacturing. Close collaboration with Argonne National Laboratory and General Motors are expected.

这个学术界与工业界联络（GOALI）/合作研究项目的资助机会的目标是开发环境友好的最小量润滑磨削工艺，使用纳米流体代替传统的磨削液。 纳米流体是一种新型的传热和抗磨流体，通过在水基或油基流体载体中分配小于40 nm的固体颗粒而产生。 纳米流体的上级热性能和摩擦学性能使其特别适用于微量润滑磨削。 在这项研究中，将评估使用添加铜，硼酸钛和碳纳米管纳米颗粒的纳米流体。 将开发一种新的流体输送系统，使用喷射器喷嘴将高压纳米流体喷雾精确地输送到磨削区，并使用水雾喷雾冷却工件和砂轮。 将测试真空系统，以收集最少量润滑磨削中的近干切屑。磨削被认为是一种不环保的制造工艺。 传统上，磨削液的选择和输送是基于实现有形生产率和成本目标的需要，而往往忽视了看似不那么有形的环境和安全危害。 如果成功的话，这个项目可以通过开发基于总成本方法的“绿色”磨削工艺来改变这种模式。 它可以在工业中产生深远的影响，使人们意识到磨削液的智能利用。 这项研究也可以推进纳米技术的环境友好型制造。 预计将与阿贡国家实验室和通用汽车公司密切合作。
