GOALI/Collaborative Research: Minimum Quantity Lubrication (MQL) Grinding Using Nanofluids

该学术联络/合作研究项目的目标是开发使用纳米流体代替传统磨削流体的环保型最小量润滑磨削工艺。纳米流体是一种新型的传热和抗磨流体，通过在水或油基流体载体中分配小于40纳米的固体颗粒而产生。纳米流体优越的热学和摩擦学特性使其特别适用于少量润滑磨削。在这项研究中，纳米流体使用添加铜，硼酸钛和碳纳米管纳米粒子将进行评估。将开发一种新的流体输送系统，该系统使用喷射器喷嘴将高压纳米流体雾射流精确地输送到磨削区域，并用水雾喷雾冷却工件和砂轮。一个真空系统将被测试收集近干屑在最少量的润滑磨削。磨削是公认的对环境不友好的制造工艺。传统上，磨削液的选择和交付是基于实现实际生产率和成本目标的需要，而往往忽略了看似不太明显的环境和安全危害。如果成功，该项目可以通过开发基于总成本方法的“绿色”研磨工艺来改变这种模式。它可以在工业中带来对磨削液的智能利用的认识产生深远的影响。该研究还可以推动纳米技术向环保制造的方向发展。与阿贡国家实验室和通用汽车公司密切合作。

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.
