This paper discusses the experimental characterization on micro-drilling process of titanium alloy (Ti-6Al-4V), which is one of representative difficult-to-cut materials, with the nanofluid minimum quantity lubrication (nMQL). The miniaturized machine tool system is set up, and then, a series of micro-drilling experiments are performed under compressed air (CA), pure MQL and nMQL for a comparison...
This paper discusses the optimization of environmentally benign nanofluid MQL micro-drilling process using nanodiamond particles based on a response surface methodology (RSM) and genetic algorithm (GA) in the cases of base fluid of paraffin oil and vegetable oil. In order to obtain regression functions of drilling torques and thrust forces in terms of process factors such as drill diameter, feed rate,...
