“…In addition to the electronic properties and chemical composition, the surface structure of DLC is important in a wide range of applications, for example in coating machine tools for use in dry, near-dry and oil-lubricated drilling [2,13,14]. In biomedical applications, the topography, composition and electrical properties are all of importance, in devices from sensors to hip joints, where DLC has been used as a diffusion barrier and to inhibit adhesion of bacteria such as Staphylococcus epidermidis [15].…”

Diamond-like carbon (DLC) films were deposited utilising plasma enhanced chemical vapour deposition (PECVD) with acetylene precursor, diluted with 0 -45% argon.Electron paramagnetic resonance (EPR) measurements show the presence of one paramagnetic centre with no change in spin population over the range of film deposition conditions. However, the EPR linewidth decreases with increasing argon content of the precursor mix, suggesting an enhancement of motional narrowing due to an increase in electron delocalization, related to an increase in the sp 2 cluster size.Atomic force microscopy (AFM) measurements indicate the surface of the DLC is formed of nanoscale asperities of material. With radii of tens of nanometres for films deposited with zero argon, the size of the features increases with the argon dilution of the acetylene. Energy dispersive x-ray analysis and electrical measurements further elucidate the changes in film structure.

“…dry machining is safer for the machinist as well as the environment and also contributes to the reduction in overall manufacturing costs. Dry machining also leads to reduction of the use of cutting oils, associated energy consumption and industrial waste 1 . These emerging trends in dry machining have attributed to intricacies in machining aluminium and its alloys which is due to its chemical affinity to different coating materials and low melting point.…”

Effect of Coating and Polishing of Cutting Tool on Machined Surface Quality in Dry Machining of Aluminium Alloy

et al. 2020

Surface quality is one of the major concerns in any machining process. To achieve the higher surface finish, mostly concentrated on machining parameter optimisation. This study has been carried out to study the effect of coating and polishing of flute surface of the solid carbide (WC-Co) endmill cutters on machined surface quality obtained during dry machining of Aluminium alloy 24345WP. Experiments were conducted on Aluminum workpieces with Ø6 mm 2 flute end- mill cutter with and without coating/polishing and their effect on surface quality studied for linear as well as areal surface roughness parameters using white light interferometery. The study concludes that polished flute tool, despite their non-sharp cutting edges, gives considerably better surface finish due to its lowering of chip tool friction. This was also supported by the results obtained from scanning electron microscopy of the cutting tool edge as well as optical microscopy of the obtained machined surface.

“…Thereby, new alternative methods to replace cutting fluids were developed [ 16 ]. Among them, dry machining minimizes the negative environmental effects, thermal shock in discontinuous machining operations, and health risks for workers [ 17 , 18 , 19 ]. However, the total absence of cutting fluids causes quick tool wear and the degradation of workpiece surface integrity [ 20 , 21 ].…”

Experimental Parametric Relationships for Chip Geometry in Dry Machining of the Ti6Al4V Alloy

et al. 2018

View full text Add to dashboard Cite

The Ti6Al4V alloy is included in the group of difficult-to-cut materials. Segmented chips are generated for a wide range of cutting parameters. This kind of chip geometry leads to the periodic variation of machining forces, tool vibrations, and work part-tolerance inaccuracies. Therefore, the analysis of chip morphology and geometry becomes a fundamental machinability criterion. However, few studies propose experimental parametric relationships that allow predicting chip-geometry evolution as a function of cutting parameters. In this work, an experimental analysis of the influence of cutting speed and feed rate on various chip-geometric parameters in dry machining of the Ti6Al4V alloy was carried out. In addition, the chip morphology and chip microstructure were studied. A clear dependence of certain chip-geometric parameters on the cutting parameters studied was found. From the experimental data, several parametric relationships were developed. These relationships were able to predict the evolution of different geometric parameters as a function of cutting speed and feed, within the tested range of values. The differences between the proposed models and the experimental data were also highlighted. These parametric equations allowed quantifying the value of parameters in which the trend was clear.
