“…This caused lower surface roughness, especially when employing cutting oil (Fig. 12) [46]. Sole implementation of using nanodiamond nanofluid MQL has been shown to diminish surface roughness because of ballbearing influence of nanodiamond [28].…”

“…Approximately 32% decrement in areal surface roughness was achieved with sunflower oil MQLbased micro-milling of Inconel 718 in comparison to dry micro-milling [45]. Kieren-Ehses et al [46] used cutting oil, sodium dodecyl sulfate (SDS), and isopropanol applying with the MQL method in micro-milling of cp-titanium. Decreased adhesion because of usage of cutting fluid was seen at slot bottom.…”

This article provides an overview of micro-milling operation with a focus on cutting fluids and reviews and discusses dry machining, flood, cryogenic cooling, usage of minimum quantity lubrication (MQL) approach, nanoparticle suspensions, and vegetable oils. In conclusion, the article highlights the future trends and research gaps in field of micro-milling with cutting fluids. Based on works, it can be concluded that researchers explore substitutes for traditional cutting fluids in micro-milling, including vegetable oils, nanofluids, cryogenics, solid lubricants, and de-ionized water. Most cutting fluid studies have focused on micro-milling of aluminum, steel, and titanium, with surface roughness being the most measured output in micro-milling work involving cutting fluids. Overall, the article highlights the need for further research in various aspects of micro-milling operations with cutting fluids, including the development of new cutting strategies, the optimization of cutting fluid delivery methods, and the evaluation of various machinability parameters.

“…In a follow-up study, an SDS solution, isopropanol, and the commercially available synthetic oil DiaMond 80 were used via MQL in a micro milling experiment. The tools used in combination with DiaMond 80 exhibited the lowest amount of adhesions on the cutting edge and produced the best surface quality in the machined microchannels [16].…”

“…Adhesions have a strong bond with the abrasive layer; if removed, a portion of the abrasive layer is also detached off its base body [15]. In micro milling, adhesions come in the form of build-up edges that occur on the cutting edges of micro end mills when machining ductile metallic workpieces [16].…”

Micro machining with micro pencil grinding tools (MPGTs) is an emerging technology that can be used to manufacture closed microchannel structures in hard and brittle materials as well as hardened steels like 16MnCr5. At their current operating conditions, these tools have a comparatively short tool life. In previous works, MPGTs in combination with a minimum quantity lubrication (MQL) system were used to manufacture microchannels in 16MnCr5 hardened steel. The study has shown that steel adhesions clog the abrasive layer of MPGTs, most likely resulting from insufficient lubrication. In this paper, a metalworking fluid (MWF) supply method was developed to improve the process: a submerged micro grinding process, in which machining takes place inside a pool of MWF. In this study, the effect of seven types of MWFs on material adhesions at the bottom surface of the tool is evaluated. Equivalent good MWFs are then compared in a micro pendulum grinding experiment till failure.

“…Thus, in the machining of difficult-to-cut material, the use of cutting fluid can be considered essential. Kieren-Ehses et al [8], during the micromilling of commercially pure titanium, observed that the cutting forces fell down when employed the cutting fluids, reducing the built-up edge formation. In the micro-milling of Ti-6Al-4V titanium alloy, Ziberov et al [9] observed an improvement in the quality of the machined surface when employed a lubri-cooling condition, however, in dry condition, the tool life was higher.…”

The sustainable machining is a delicate issue because it does not depend only on the environment aspects. A simple solution would be to remove the use of cutting fluids, however, in the machining of difficult-to-cut materials, the use of cutting fluid can be strongly recommended. In these materials, the high temperature during the cut can cause damages that compromise the component efficiency, likes cracks, microstructure, and others. In recent years, the micro-cutting has been employed to obtain more detailed components and/or great surface quality, regardless of dimensions. In this work, the orthogonal micro-cutting of commercially pure titanium was investigated, employing the dry condition and the use of cutting fluid at different temperature, room temperature and the cooled. To know the cutting fluids effects, forces, friction, specific cutting energy, chip compression, chip deformation, and shear plane angle was compared. These outcomes indicated that, under the test conditions, the use of cutting fluid, principally when cooled, had a negative effect on micro-cutting performance.
