In recent years, the need for eco-friendly machining processes has increased dramatically in order to limit excessive use of conventional cutting fluids, thereby reducing their negative effects on both environment and operator’s health. this context, environmental alternatives such as dry cutting, minimum quantity lubrication (MQL), nanofluid-assisted MQL have been demonstrated be effective ove...

The positive effects of nanofluid-assisted minimum quantity lubrication include improved performance during machining and environmental sustainability. In the present study two cutting parameters levels such as feed rate 0.05 (mm/rev)- depth cut 0.1(mm)-cutting speed 80(m/min) 0.15(mm/rev)-depth 0.3(mm)-cutting 200(m/min) has been used in hard turning D2 steel. It was determined that 0.3% ZrO 2...

The effects of surface topography, processing, and environment conditions during tribological contact between Ti6Al4V titanium alloy UHMWPE friction pairs were systematically evaluated. Hence, in this research the polyethylene samples (blocks) having a constant roughness rubbed against counter-bodies (rollers) made with different surfaces. counter-samples manufactured using either dry machining...

The quest for advanced cooling/lubrication approaches energy-efficient, eco-benign, and cost-effective sustainable machining processes is garnering attention in academia industry. Electrical embodied energy consumption plays an important role reducing CO2 emissions. In the present study, new empirical models are proposed to assess indicators. energy, environmental burden, cost of coolant/lubric...

The use of composite materials and composite stackups in aerospace and automotive applications has been and will continue to grow at a very high rate due to the high strength and low weight of the materials. One key problem manufacturers have using this material is the ability to efficiently drill holes through the layers to install fasteners and other components. This is especially true in sta...

The lubrication capacity and penetration ability of the minimum quantity cooling lubrication-based strategy is linked with specific parameters (oil flow rates air pressure), cutting conditions, chip formation. It points out complex selection involved in MQCL-assisted to attain optimal machining performance. Lubrication during metal operations a phenomenon, as it strong function conditions. In a...
