    Friction between cutting tool and workpiece generates heat, which can shorten tool life and impair the quality of machined parts. Thus, the use of appropriate lubricants is required to mitigate these issues. In this research, the use of different weight concentration of graphene nanoparticles (0.1 %, 0.5 % and 1.0 %) to augment commercially available vegetable-based oil, LB3000 was investigated using tribological test. Their performances were evaluated in form of the coefficient of friction, wear scar diameter, kinematic viscosity and thermal conductivity. Higher concentration of graphene was found to be more effective in terms of lowering coefficients of friction, reducing wear scar diameter, and improving kinematic viscosity and thermal conductivity. This study clearly demonstrates that a suitable combination of graphene nanoparticles in oil can improve tribological behaviour as well as lubrication performance.

    Cutting fluids are frequently aimed to enhance machinability through cooling, lubricating and flushing actions. However, their use in machining creates major concerns in terms of health footprint and environmental effects throughout their lifecycle. Alternative methods, such as dry cutting and minimum quantity lubrication, were used to mitigate these issues. This research also will investigate the effect of swept angle selection, 30% and 60% of tool diameter step over under different cutting conditions during milling of aluminium alloy material. Their impact on tool wear, surface roughness, burr and chip formation were compared. Results pointed that the application of lower swept angle in conjunction with minimum quantity lubricant system has significantly reduced tool wear, decreased burr and chip formation, as well as improved surface quality as compared to dry machining. The work clearly shows how the importance of swept angle selection and cutting condition in refining machining performance could improve the machinability of the material.

    Shape memory alloys of Nickel Titanium (NiTi) reveal a reversible diffusionless transition between phases, resulting in unique properties and applications. It is widely used in varieties of products; especially in aerospace and medical fields. Yet, these alloys known as hard-to-machine materials owing to their properties of unconventional stress-strain behaviour, high work strain hardening and high ductility. That’s why their machinability is a major issue. The common drawbacks are serious burr formation, rapid tool wear, poor surface quality and high cutting force. This paper puts forward any possibilities to enhance the machining performance through paper reviews from previous researchers. A notable finding is that the machinability issues can be reduced or lessened by changing the cutting parameters and cutting conditions in order to improve the machinability of NiTi alloys.
