Heat Transfer Mechanism of Minimum Quantity Lubrication Grinding

Abstract

Grinding temperature rise at the grinding interface has a great bearing on workpiece surface quality and service life of grinding wheel. In order to study influence degree of temperature on workpiece and analyze heat transfer at the grinding interface, as thermal influence at the grinding interface is regarded as a moving heat source on workpiece surface, influence of heat source on heat transfer will be investigated in the gradual expansion form of heat source by point, line, and surface on the theoretical foundation in Chapter 3. The influences of heat quantity transferred to workpiece and energy proportionality coefficient will be studied according to convective heat transfer theory on workpiece surface so as to provide a theoretical foundation for heat transfer of grinding temperature field model in the finite element simulation software.
