Experimental analysis of process parameters in drilling nimonic C263 alloy under nano fluid mixed MQL environment

Abstract

Nimonic C263 is a super alloy and it is difficult to cut. As this alloy possess high proportion of chromium, cobalt, and molybdenum, which fortify the material by solution hardening, which inhibits the dislocation movement, resulting in higher plastic deformation. In this research, an attempt has been made to model, analysis and investigate the machining characteristics such as thrust force, temperature at drill cutting edge, flank wear and surface finish during drilling of this alloy using silver nano fluid mixed Minimum Quantity Lubrication (MQL) environment. Residual stress at various combinations of process parameters was also observed and discussed. RSM based empirical models of the process parameters and optimization of multi response was developed. Thrust force, Temperature at drill cutting edge, surface roughness and tool wear affected by feed rate (percentage of contribution-60%), spindle speed (percentage of contribution-88.63%), spindle speed (percentage of contribution-71.42%) and feed rate (percentage of contribution-67.76%) respectively followed by other parameters.

A review on conventional and nonconventional machining of Nickel-based Nimonic superalloy

“…The authors concluded that the FR followed by the CS, the concentration of nanoparticles, and the coolant pressure was the order of importance in deciding the tool wear. It was also reported that the temperature and the SR increased with a lower coolant pressure and nanoparticle concentration [87]. Nagaraj et al [88] developed a FEMbased simulation model to predict the force and temperature generated during the drilling of Nimonic C263 using a coated carbide drill bit.…”

State-of-the-Art and Future Perspectives of Environmentally Friendly Machining Using Biodegradable Cutting Fluids

“…As discussed previously, the MQL technique is often used to minimise the use of cutting fluids [79,80]. In one research work, the turning operation was conducted on Titanium alloy using a polycrystalline diamond tool to optimise various parameters resulting in a decrease in R a [81].…”
