ICERI, D. M. et al. Grinding of alumina ceramics with different cooling and lubrification techniques: conventional and minimum quantity of lubrification (MQL). Cerâmica [online]. 2012, vol.58, n.345, pp.84-89. ISSN 0366-6913.

The great technological growth and the improvement needs, a material that has gained a wide range in mechanical engineering is the ceramics because of its advantages beyond steel, having chemical and mechanical better properties. However, its machining is a difficult and delicate process, which requires a careful attention to their study. Moreover, the grinding process is one of the methods which is producing good results but, there is a big problem around this, which is the excessive use of cutting fluids that becomes a global concern, since this fluids generate serious social and environmental problems, causing, in this way, a great interest in research on alternative methods to reduce consumption and improve the performance of cutting fluid used. This work aims to compare two techniques of lubrification and cooling in the grinding process, the conventional and the optimized methods. The second one is an option to decrease the volume of fluid used, using the application principle of a smaller amount of cutting fluid applying locally a high speed flow, obtaining environmental and socioeconomic benefits. The analysis of the work will be done based on the evaluation of the output variables of the flat grinding process such as the behavior of the roughness and grinding wheel wear, whereas they can evaluate the process making a relationship between part quality versus cost. With this analysis, we intend to evaluate if the optimized method is a viable substitute to conventional method in the flat grinding process.
