Ceramic coating materials own some advantages, for example high-rigidity, good abradability and good performance under high temperature. At the same time, ceramic coating materials are also difficult-to-machine materials. High machining precision and efficiency can be obtained in grinding WC-Co coating by cup wheel. The affection of grinding temperature is very important for grinding processing. But there is no research on grinding temperature of WC-Co coating by cup wheel. So in this paper, grinding temperature by cup wheel is researched on theory, the new concept, which is effectiveness width of arc moving heat source, is presented, and theoretical formula of grinding temperature is also built. Then experimental research on grinding temperature of WC-Co coating by cup wheel is done by use of thermocouple temperature measurement technology. The experimental results show the validity and effectivity of the theoretical formula. The affection of grinding parameters to grinding temperature is researched also.

Estimation of grinding temperature is essential for the better understanding of the grinding process. The present study attempts to correlate the carbon depletion in mild steel chips to the heat produced at the grinding zone. A database is generated by heating the workpiece material to various temperatures and studying the carbon content. After grinding, the carbon content in the chip is estimated and compared against this base data of carbon content vs. the temperature of the parent material. The carbon content gives an estimate of the temperature that the chip would have undergone during grinding.

“…In fact, the rapid heating and cooling kinetics reached during the grinding process may cause microstructural transformation and thermal plastic deformation in the near surface of the workpiece and thereby introduce significant residual stresses [1,2,3,4]. In the case of hand grinding process literature is very poor in terms of available data concerning the influence of the process parameters on the induced subsurface integrity [5]. However, some investigations in grinding process on relevant problems such as hardening, structural transformations, residual stresses and heat damage can be helpful [6,7].…”

For complex part geometry, hand grinding is one of finishing and super finishing process the most used in mechanical industry. Surface integrity is today one major concern for industrials. The surface integrity is defined by a set of important characteristics of ground surface as surface geometric parameters (roughness, …), mechanical behaviour of the subsurface (hardness, residual stress, …) and structural changes of the material in the near surface. High heat and pressure, high strain and strain rate observed during hand grinding process, strongly influence surface integrity. Therefore, the surface behaviour, in terms of resistance to corrosion and crack initiation depends on how the process was conducted. The purpose of this study is to understand the effects of thermal and mechanical plastic deformation induced on the surface of components. The action of the disc-grinding wheel on the workpiece is modelled by a moving heat flux on the surface. The challenge is to be able to find the shape and intensity of thermomechanical load entering the workpiece in accordance
