“…The R a values for treatment 36 m min −1 and 0.25 mm rev −1 and treatment 24 m min −1 and 0.15 mm rev −1 were 1.77 and 0.915 μm, respectively. Similar results were also reported in the literature, but for machining different alloy steel V100CrMoV5 using microlubrication as compared with dry machining. The maximum R a value of 4 μm for microlubrication machining was reported as compared with 16 μm for dry machining under similar cutting conditions.…”

Microlubrication is a green machining technique that reduces the amount of cutting fluid during the machining process. Its effect on subsurface microstructural integrity is a very important aspect for the functionality of a machined component, but it is often neglected and requires advanced characterisation techniques. The focus of this study is to investigate the influence of microlubrication using a biodegradable vegetable oil‐based cutting fluid to characterise the subsurface microstructural integrity during end milling of AISI 1018 steel. Vickers microhardness was measured along the cross section of the machined component from the surface edge to inside the bulk, while transmission electron microscopy was conducted inside the subsurface deformation zone to quantify the dislocation densities. It was determined that increased dislocation densities near the workpiece edge resulted in increased microhardness with reduced tool wear. Thus, microlubrication machining is a sustainable green machining process that does not significantly compromise the subsurface integrity of the workpiece material.

“…However, the cost of cutting fluids is increasing owing to increasingly stringent environmental standards for fluid handling and disposal, and these are likely to be further tightened in proposed national and international legislation [1]. Although dry and semi-dry machining is an attractive option, it is currently unavailable in many operations as cooling cannot be achieved [2,3]. Therefore, cutting fluids will continue to be required.…”

Tribological Properties of Cutting Fluid Sterilized by Atmospheric-Pressure Plasma Treatment

et al. 2018

Plasma jet sterilization of cutting fluid was performed under atmospheric pressure, and the tribological properties of the resulting fluid were investigated. The mechanisms of atmospheric-pressure plasma jet sterilization were also clarified. The number of bacterial colonies in the sterilized fluid was reduced by more than 90% compared with the untreated fluid. After exposure to ultraviolet light, no comparable reduction was observed. We concluded that the sterilization observed in the study was caused by the reaction of excited N 2 , N, and Ar. The IR spectra of the plasma-treated cutting fluid were the same as those of the untreated fluid. However, the transmittance of the C=O peak decreased in proportion to the discharge voltage. The treated cutting fluids maintained a low friction coefficient 2.4 times longer than the untreated fluid. The sliding angle and adhesive energy of the untreated cutting fluid were considerably lower than those of the unused cutting fluid. Furthermore, the sliding angle and adhesive energy of the plasma-treated cutting fluid were higher than those of the untreated cutting fluid. Therefore, we consider that the lower friction coefficient of plasma-treated cutting fluid as compared to that of the untreated cutting fluid is related to this result. The study demonstrated that the life of a cutting fluid can be prolonged by this novel plasma treatment, with an associated improvement in tribological properties.

“…Estudo realizado por WERDA et al [13] realizou estudo com diferentes métodos de arrefecimento e lubrificação, foram comparados o desgaste da ferramenta, rugosidade da superfície da peça e temperatura. Os resultados concluíram que, a rugosidade da superfície foi melhor na aplicação da névoa de óleo e que o uso da velocidade de corte baixa na presença de água/óleo combinados com névoa permitiu atingir o menor desgaste da ferramenta.…”

Resumo: O objetivo deste trabalho é realizar um estudo sobre as técnicas de minimização de fluido de corte em processos de usinagem. Diante dos danos ambientais provocados pela utilização de fluidos de corte nos processos de usinagem, estudos vem dando ênfase a tecnologias ambientalmente que visem à preservação do meio ambiente e conformidade com normas ambientais. O setor industrial busca constantemente alternativas que possam substituir ou reduzir o uso de fluidos de corte na usinagem de metais, dentre elas, destaca-se a usinagem sem fluido de corte e a técnica de Mínima Quantidade de Lubrificante (MQL).
