Exploration of Effectiveness of Ionic Liquid Adopted as an Additive to the Vegetable Oils

Abrasive material removal processes are quite challenging due to high temperatures and power requirements. To achieve quality products, unwanted material removal is required from the base processed material. In the process of removing unwanted material from the workpieces, different operations are involved such as threading, grinding, and turning operations. The main parameters of the material removal process are feed, speed, and depth of cut. During the material removal process, heat is generated from the workpiece as well as tool. Therefore, time to time, lubrication is required to tackle with the problems that rise from generation of heat. Minimum quantity lubrication is an alternate of general cooling systems to protect the environment as well as human health. In the present investigation, attempt has been made to explore the surface roughness, grinding forces, specific grinding energy, grinding temperature, and G ratio in MQL grinding of AISI 52100 steel. The three input variables are considered in this investigation, namely vegetable oils, air pressure, and an ionic fluid. Better results have been attained with the MQL grinding by using coconut oil under different parameters. Signal-to-noise (S/N) ratio as per Taguchi design revealed MQL as significant parameters for surface roughness, whereas feed can be set within the range. Taguchi optimized conditions were validated through multiple response optimization using desirability function.
