Thermal aspects of the grinding process

Abstract

Grinding is a commonly used process for material removal. It has been used for a long time mainly as a finishing process, although this situation is changing, with the development of creep feed grinding, and high efficiency deep grinding. In these processes, grinding is a stock removal, and finishing operation. The quality of the finished component is usually assessed in terms of form, surface roughness, and thermal damage. In this thesis, thermal aspects of the grinding process are examined. These aspects include: the manner in which the workpiece geometry in form grinding influences the grinding temperatures; the identification of the temperature at which tensile thermal residual stresses manifest themselves in the workpiece; the ground plane temperature in deep cut grinding; the role of the coolant in creep feed grinding.
