Thermal stresses of grinding plays an important role on the fatigue and wear resistance of the component. A comprehensive analysis of thermal stress induced by surface grinding has been conducted with aid of the finite element method. To obtain a reliable figure of thermal stress induced by grinding, temperature-dependent properties of workpiece materials were taken into accountget price
Thermal aspects of grinding are analyzed in detail since it is argued that temperature controls the effect of grinding on workpiece surface integrity. Transient and steady state heat partition in sliding contact is discussed in detail. This leads to a complete thermal model for heat partition and temperatures in surface grinding. Numerical predictions of the model are shown to agree withget price
Feb 25, 2003 In grinding, stock removal rate is often limited by thermal damage to the ground component. A significant portion of the energy used in removing stock transmits to the workpiece as the heat which causes damage to the ground surface. In order to avoid thermal damage, the amount of heat entering the workpiece must be controlledget price

Creep feed grinding and conventional surface grinding are compared. Creep feed grinding is faster and has better surface quality and grinding wheel endurance. However, problems are caused by its higher cutting forces, driving powers, and thermal load on workpiece. Open soft grinding wheels have suitable chip formation and coolant supply characteristics for creep feedingget price
p Due to the characteristics of the grinding process, thermal damage may occur in the workpiece surface, resulting in the rejection of a component and considerably increasing the production costs. This study aims to analyze the heat fluxes, energy partition, and temperatures during surface grinding process with both conventional and MQL lubrication. Through the proposed analysis, the heatget price
May 14, 2019 Grinding burn or thermal damage is a common cause of machine or engine component failure. When grinding heat is not quickly detected and removed by a suitable cooling solution, it can have a big impact on the service life of the product. In order to detect grinding burn in an early stage, it is important to know what causes grinding burnget price
During surface grinding, internal material loads are generated, which take effect on the surface and subsurface zone of AISI 4140 steel. High thermal loads can result in specific material modifications, e.g., hardness reduction and tensile residual stresses, due to inappropriate combinations of system and process parameters which influence the functional performance of the ground component inget price
