Introduction
Grinding is an important process that creates precise parts with smooth and consistent surface finishes.
It is utilized in the fabrication of many everyday products, such as bearing components, and is the final
machining step in much of today's precision component manufacturing. Grinding operations are found
in nearly all applications of precision materials production, for example tape heads, disk drive platens,
medical implants, automobile roller and ball bearings, specialized optics, and mirrors. Since grinding
has relatively low material removal rates, it can create smooth surfaces while maintaining precision
tolerances. It is also a common and necessary process for machining extremely hard materials (greater
than 50 Rockwell C hardness) or brittle materials (such as silicon wafers) where operations such as milling
are not efficient or successful. For extremely hard materials such as ceramics or super-alloys, fixed abrasive
