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.
