Although chip morphology changes according to the machining method and related cutting parameters, chip formation affects the quality of the machined surface. In this context, it is very important to understand the relationship between chip morphology and surface quality, especially in materials that are difficult to machine. In the presented study, the changes in chip morphology, surface morphology, and surface quality criteria (Ra and Rz) that occurred during the milling of precipitation-hardened steel in different cutting environments were analyzed. Milling experiments were carried out in dry, MQL (minimum quantity lubrication), nano-MQL (graphene), nano-MQL (hBN), Cryo, and Cryo-MQL environments using TiAlN-coated inserts and three different cutting speeds and feed rates. While the highest values in terms of Ra and Rz were measured in dry machining, the minimum values were obtained in a nano-MQL (hBN) cutting environment. Due to the lubrication and low friction provided by the MQL cutting environment, chips were formed in thinner segmented forms. This formation reduced the chip curve radius and thus provided a more stable surface morphology. On the other hand, Cryo-ambient gas could not effectively leak into the cutting zone due to the intermittent cutting process, but it increased the brittleness of the chips with the cooling effect and provided a similar surface morphology. The values of minimum Ra and Rz were obtained as 0.304 mm and 1.825 mm, respectively, at a 60 m/min cutting speed and 0.04 mm/rev feed. Consequently, the use of nano-MQL cutting medium is seriously recommended in terms of surface quality in milling operations of difficult-to-machine materials.

“…In comparison with MQL, it was evident that decreasing of surface roughness by approximately 30%, 44% and 49% under UVA-MQL, NMQL and UVA-NMQL, respectively when the cutting speed was 100 m/min and the feed rate was 0.1 mm/rev. The ability of graphene nanoparticles to reduce the coefficient of friction is the reason for this phenomenon [53]. Moreover, in MQL machining, at the cutting speed of 130 m/min and feed rate of 0.1 mm/ rev, the application of ultrasonic vibration to the cutting tool (UVA-MQL) reduced the surface roughness by 32%.…”

The present work aims to decide on machining parameters and enhance machinability of the biomedical Ti6Al7Nb alloy using nanofluid MQL with nanoparticles of graphene (NMQL) and ultrasonic vibration assisted (UVA) machining methods were applied both separately and in a hybrid manner. Consequently, for the chosen cutting parameters, when compared to the conventional turning (CT) with vegetable cutting oil-based MQL, the UVA-NMQL hybrid method has achieved a reduction in cutting forces ranging from approximately 11% to 23%, a decrease in cutting temperatures by around 9% to 17%, and an enhancement in average surface roughness by roughly 15% to 53% across all the analyzed results compare to vegetable oil based conventional MQL turning conditions. Additionally, using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method, the optimum cutting parameters were determined as UVA-NMQL cutting condition, 130 m/min cutting speed, and 0.1 mm feed value.

Being one of the most lightweight, toughest, and most flexible materials in the world, having exceptional mechanical, electrical, thermal, and tribological properties, makes graphene and its several based materials crucial applicants for biomedical, medical, aerospace, automotive, electrical, energy, sensing, food, and other industrial sectors. Graphene is classified as a carbon allotrope, with one-thick-atom planar 〖sp〗^2 layers of attached carbon atoms tightly loaded within a crystal honeycomb lattice. Various techniques to produce graphene were established over a brief period of time, including top-down and bottom-up methods. Graphene itself can be used as a coating to improve other materials; likewise, it could be added to further composite materials. This review recaps the applications of graphene, its types, synthesis methods, and mechanical, tribological, and thermal characteristics, in addition to enhancement methods for graphene and its based materials.
