Abstract

The design of grinding wheels operating at excessive peripheral speeds has improved significantly since the 1970s, which was largely prompted by the development of the creep-feed grinding process (CFG) and its derivatives including high efficiency deep grinding (HEDG), peel grinding (PG), and the high-speed stroke grinding process (HSSG). The current work reviews the design of grinding wheels that operate within the specified safety factors that are applied by the industry through the application of various codes and industry standards developed since the introduction of high-speed grinding processes. The paper focuses on the design of plain and clamped homogeneous structure grinding wheels, reinforced and recessed grinding wheels, superabrasive segmented grinding wheels, and high-speed slotted grinding wheels that use both conventional bonded abrasive structures and vitrified and electroplated superabrasive materials such as cubic boron nitride (cBN) and diamond. The implications of grinding wheel safety are stressed, and recommendations are provided to ensure that grinding wheels continue to be operated safely at excessive peripheral speeds.
