The insert grade selection is not as directly related to roughing and finishing of exotics as it is in other materials. Instead, grade selection is more of an optimization factor – a little bit more complex, dependent upon the shape of the insert and the approach of the cutting edge and the type of operation (for example, turning, profiling or grooving and recess machining).

ABSTRACT The purpose of this study was to optimize the grinding process by the use of different types of metalworking fluids and grinding wheels. The four most important variables in the grinding process are the grinding machine, the grinding wheel, the metalworking fluid, and the type of material being ground (the part). This study limited the material ground to two different grades of steel.

Grinding is the most comprehensive and diversified of all machining methods and is employed on many materials—predominantly iron and steel but also other metals, wood, plastics, stone, glass, pottery and so on. The term covers other methods of producing very smooth and glossy surfaces, such as polishing, honing, whetting and lapping.

Components with bulk cold work cracked relatively early in BWR service, and subsequent designs restricted cold work to less than a few percent. However, surface cold work from machining, grinding, and related processes is more difficult to control, quantify, or eliminate, and has been responsible for accelerated initiation in many BWR components.
