“…According to Webster et al (1995) [5], lubrication and cooling depend on the effective delivery of fluid at the workpiece-tool interface, end high volumes are not necessary since part of the fluid does not actually penetrate the cutting region. However, the type of nozzle end its positioning strongly afecct the cutting process.…”

“…Morgan et al (2008) [16] says that a tangentially directed jet can easily disrupt the air barrier if the jet speed equals wheel speed. Webster et al (1995) [5] showed the need for jet coherency.…”

“…Noting this tendency, this paper aims to study the replacement of conventional cooling for optimized cooling and minimum quantity of lubrication in the grinding process. This finishing process minimizes the surface roughnesses and irregularities through interactions between the abrasive grains of a tool (grinding wheel) and the workpiece to be ground [4,5].…”

The is paper presents an analysis of the influence of minimum quantity lubrication (MQL), optimized and conventional cooling, using different cutting fluid volumes and flow rates, on the surface quality and integrity of hardened steel workpieces, in cylindrical plunge grinding with superabrasive CBN grinding wheels. The final quality of the workpieces were evaluated based on an assessment of output variables such as the behavior of: tangential cutting force, specific energy, surface roughness, roundness errors, acoustic emission, residual stresses, scanning electron microscopy (SEM) micrographs, and microhardness. The present analysis of the various forms of cutting fluid application identified cooling conditions which favor the minimization of cutting fluid usage, and shorter machining times without impairing the geometrical and dimensional parameters, surface finish and surface integrity of the workpieces. Among the various forms of cutting fluid application, optimized lubrication at higher outlet speeds showed the best performance, confirming the efficiency of the new nozzle concept employed in this study. The optimized and MQL processes were successful in maintaining the hardness and surface integrity of the ground workpieces. The only exception was the use of MQL with a flow rate of 40ml/h, which caused cracking and quenching of the workpiece surface. The lowest surface roughness values obtained with MQL were obtained using higher flow rates of lubricant. The surface roughness values obtained with MQL are high for the grinding process. Low-concentration CBN wheels, which are less expensive and subject to less wear, produce good results when associated with more efficient cutting fluid application techniques.

“…Como exemplo dessa utilização indevida, em muitas indús-trias, ocorre grande dispersão de fluido no momento da usinagem, gerando, dessa forma, grandes perdas. A lubrificação e a refrigeração dependem da efetiva entrada de fluido na região de corte entre a peça e a ferramenta, não havendo a necessidade de volumes elevados, considerando que parte deste não esteja penetrando na região de corte efetivamente (Webster, 1995 …”

ResumoA retificação, processo final de usinagem de uma peça, utiliza fluidos de corte com a finalidade de lubrificação, refrigeração e remoção de cavacos. No entanto, esses fluidos são extremamente agressivos com o meio. Com o avanço tecnológico a tendência mundial é produzir peças cada vez mais sofisticadas, com elevado grau de tolerância geométrica, dimensional, com bom acabamento superficial, com baixo custo e, principalmente, sem causar danos ao meio. Para tanto, ao processo de retificação está intrínseca a reciclagem do fluido de corte, que se destaca pelo seu custo. Através da variação da velocidade de avanço no processo de retificação cilíndrica externa do aço ABNT D6, racionalizando a aplicação de dois fluidos de corte e usando um rebolo superabrasivo de CBN (nitreto de boro cúbico) com ligante vitrificado, avaliaram-se os parâmetros de saída da força tangencial de corte, emissão acústica, rugosidade, circularidade, desgaste da ferramenta, tensão residual e a integridade superficial através da microscopia eletrônica de varredura (MEV) dos corpos-de-prova. Com a análise do desempenho do fluido, do rebolo e da velocidade de mergulho, encontraram-se as melhores condições de usinagem propiciando a diminuição do volume de fluido de corte e a diminuição do tempo de usinagem, sem prejudicar os parâmetros geométricos e dimensionais, o acabamento superficial e a integridade superficial dos componentes.Palavras-chave: ABNT D6, retificação, velocidade de mergulho, rugosidade, circularidade; fluidos de corte, mínima quantidade de lubrificação, integridade superficial.
