“…The main challenge faced by manufacturers in the machining of difficult-to-machine materials is the generation of high temperatures. Harder materials usually produce a higher machining temperature when compared to softer materials as they possess a higher specific cutting energy, higher friction and deformation [72]. wet machining with its pattern being similar to that of dry machining [73].…”

Government legislation and public opinion are the main drivers behind the movement of manufacturing companies towards sustainable production. Fundamentally, companies want to avoid future financial penalties and the industry is therefore under pressure to adapt new techniques and practices in order to become environmentally friendly. The cost efficiency of metal cutting operations is highly dependent on accuracy, excellent surface finish and minimised tool wear and, to this end, has traditionally made abundant use of cutting fluid in machining operations. However, these cutting fluids have been a major contributor to environmental and health issues. In recent years an enormous effort to eradicate these adverse effects has been made with one important focus being the implementation of minimum quantity lubrication (MQL). In the present work the authors have reviewed the current state of the art in MQL with a particular focus on drilling, turning, milling and grinding machining operations.Overall it is concluded that MQL has huge potential as a substitute for conventional flood cooling.

“…Previous research shows that the TiB 2 coating with optimized properties can be very efficient when a strong buildup edge forms [11]. This is typical for rough turning operation at low speeds [12]. However, at the higher speeds (at finishing operation), the buildup is removed from friction surface [13] and cratering becomes predominant [14].…”

Tribological phenomena and tool wear mechanisms during machining of hard-to-cut TiAl6V4 aerospace alloy have been investigated in detail. Since cutting tool wear is directly affected by tribological phenomena occurring between the surfaces of the workpiece and the cutting tool, the performance of the cutting tool is strongly associated with the conditions of the machining process. The present work shows the effect of different machining conditions on the tribological and wear performance of TiB 2 -coated cutting tools compared to uncoated carbide tools. FEM modeling of the temperature profile on the friction surface was performed for wet machining conditions under varying cutting parameters. Comprehensive characterization of the TiB 2 coated vs. uncoated cutting tool wear performance was made using optical 3D imaging, SEM/EDX and XPS methods respectively. The results obtained were linked to the FEM modeling. The studies carried out show that during machining of the TiAl6V4 alloy, the efficiency of the TiB 2 coating application for carbide cutting tools strongly depends on cutting conditions. The TiB 2 coating is very efficient under roughing at low speeds (with strong buildup edge formation). In contrast, it shows similar wear performance to the uncoated tool under finishing operations at higher cutting speeds when cratering wear predominates.

“…This leads to the application of particle-reinforced metal-matrix composites (MMCs) in automobiles and aircrafts [11], and possibly in biomedical fields [12,13]. The wear resistance of MMCs depends on the properties of reinforcements as well as the working condition and rubbing materials [14].…”

The effect of reinforcement on wear mechanism of MMCs has been investigated in this paper by considering different parameters, such as, sliding distance (6 km), pressure (1.4-11 bar) and sliding speed (230-1480 rpm). The explicitness was introduced by comparing wear mechanism of an MMC and corresponding matrix material side by side under similar experimental conditions on a pin-on-disc wear machine. The pins were made of matrix material is 6061 aluminum alloy and, MMC which consists of 6061 aluminum alloy reinforced with 10 volume % Al2O3 particles (6-18 μm). The disc was made of steel. The major findings are: (1) MMC shows much higher wear resistance than the corresponding matrix material, (2) unlike matrix material the wear of MMC is very much linear and possible to predict easily under the conditions considered in this investigation, (3) the wear mechanism is similar for both materials other than the three body abrasion in case of MMC and (4) the reinforced particles resist the abrasion and restricts deformation of MMCs which cause high resistance to wear. These results reveal the roles of the reinforcement particles on the wear resistance of MMCs and provide a useful guide for a better control of their wear.
