MINIMUM QUANTITY LUBRICATION GRINDING USING NANOFLUIDS

Grinding is widely used in the manufacture of §components requiring fine tolerances and smooth §finishes; however, it is recognized as one of the §most environmentally unfriendly manufacturing §processes. Large amount of cutting fluids are used §in grinding for a variety of reasons such as §improving wheel life, reducing workpiece thermal §damage and improving surface finish. Government §regulation, environmental protection, public §awareness, and the need for cost reduction have all §promoted the development of new environmentally §conscious grinding processes.§§Therefore, the author proposed Minimum Quantity §Lubrication (MQL) grinding in this book by focusing §on the cutting fluids, grinding wheels, and thermal §management. Nanofluids, a new class of fluids §engineered by dispersing nanometer-size solid §particles in base fluids to increase heat transfer §and tribological properties, were studied as §potential cutting fluids. The insufficient cooling §problem of MQL grinding can be improved by using §vitrified bond CBN wheels. A grinding thermal model §based on the finite difference method has also been §developed to investigate the thermal aspects in the §grinding process.
