What is Magnetorheological based minimum quantity lubrication (MR-MQL) with additive n-CuO about?

This work is intended to focus on the development and investigation of a novel designed magnetorheological based minimum quantity lubrication (MR-MQL) on turning operation of Monel K500 alloy. Nanosized CuO is used as a binder in magnetorheological fluids to promote lubricity on the tool chip interference. Experiments were conducted with operating conditions suich as cutting speed (95-125 m/ min), feed rate (0.050-0.1 mm/rev), and depth of cut (0.25-0.75 mm) and variable rheological conditions such as working current (0-27 A) of the electromagnetic tool insert and flow rate (0-10 ml/min). Results obtained from the MR-MQL process prove that the cutting tool temperature was reduced by 9.36% when compared with the MQL process and surface roughness was reduced by 26.58% when compared with the MQL process. Microstructural analysis clarifies the wear scar zone reduction due to Cu 2 C 3 intermetallic compound formation near the tool tip interference.
