“…A short tool life is a basic problem to impair the machinability of nickel-based alloys and limits their machining efficiency. Many studies focused on the tool materials and their wear mechanisms (Costes et al, 2007;Devillez et al, 2007;Ezugwu et al, 2004Ezugwu et al, , 2005Deng et al, 2005). Some new tool materials such as ceramic, CBN and cemented carbide tools have been developed through the advanced technologies.…”

“…In the industry, wearing of the tool material during machining processes is a major concern (Maruda et al, 2017). To reduce the coefficient of friction and wear various lubricants are used (Ezugwu et al, 2004). The waterbased emulsion emerged as a good coolant and lubricants because of their availability as well as better thermal conductivity and low viscosity (Xia et al, 2017).…”

In the present study, the tribological performance of water-based emulsion (lubricant) was investigated by blending carbon fillers such as graphene nanoplatelets and multiwall carbon nanotubes using pin-on-disc tribometer. It was noticed that addition of GnP and MWCNT in water-based emulsion (conventional lubricant) increases the thermal conductivity and viscosity as compared to conventional lubricants. The nanolubricants were supplied with minimum quantity lubrication (MQL) technique at a constant flow rate and pressure in the sliding zone. The addition of 0.8 wt.% concentration of GnP showed 58.39% reduction in coefficient of friction and 61.80% reduction in wear depth compared to the conventional lubricant. Similarly, for 0.8 wt.% concentration of MWCNT showed 26.27% reduction in coefficient of friction and 47.35% reduction in wear depth compared to the conventional lubricant. The sliding surface micrographs were also investigated to explain the synergistic effect of nanoparticles.

“…The functional characteristics of products including their fatigue, friction, wear, light reflection, heat transmission, and lubrication will all affect the surface roughness [26]. When the product is exposed to extensive machining, we may observe slight differences in the surface roughness because of the on-going wear produced at the coated carbide cutting edge and the temperature reduction at the cutting by the coolant, which is active all through the machining of Inconel 718 [27]. Hence, we can see the significance of lubrication in end milling machining.…”

This paper presents an experimental investigation of coated carbide cutting tool performance on the surface roughness of aluminum alloy 6061-T6 machining through end mill processes using the minimum quantity lubrication technique. Process parameters including the cutting speed, depth of cut and feed rate are selected. The central composite design method is used for design of experiments. Two types of coated carbide tool are used in this experiment -an uncoated tungsten carbide insert and TiAlN+TiN-coated carbide insert. The analysis of variance method is utilized to validate the experimental data and to check for adequacy. The response surface method was used to develop the mathematical models and to optimize the machining parameters. Second-order regression models are developed based on the surface roughness results. It is observed that the surface roughness depends significantly on depth of cut and feed rate, followed by spindle speed for both the coated carbide inserts. The performance of the dual-layered coating of TiAlN+TiN is competent as compared to the surface quality obtained with TIAlN-coated inserts. The results can be used as an example of MQL applied to the machining of aluminum alloys, providing economic advantages in terms of reduced lubricant costs and better machinability.
