Part of the Fundamental Manufacturing Processes Video Series, this program focuses on grinding and how it is used to shape and finish high precision workpieces made from metals and nonmetals. It features segments on precision grinding methods, abrasives and grinding wheels, balancing, and dressing grinding wheels, grinding safety, and workpiece surface finish.
The abrasives and grinding wheels segment explores grinding wheel abrasives, such as aluminum oxide, ceramic, silicon carbide, cubic boron nitride and diamond, as well as abrasive grains, abrasive bonds, pore structure, and dressing procedures.
The grinding safety segment emphasizes employee safety while outlining the proper handling and care of wheels, visual inspection, and ring testing to determine wheel integrity.
The grinding process segment examines the grinding process parameters and the resulting force, friction, and heat relationships.
The precision grinding methods segment covers cylindrical grinding, internal diameter (ID grinding), centerless grinding, surface grinding processes and machine types, and nomenclature.
The workpiece surface finish segment covers the process variables that contribute to the properly ground workpiece surface finish, such as feed rate, machine rigidity, and workpiece materials.
