Process Parameter Optimization and Experimental Evaluation for Nanofluid MQL in Grinding Ti-6Al-4V Based on Grey Relation Analysis

Titanium (Ti) alloy is a kind of typical plastic material and it has been extensively applied to aerospace industry in China and foreign countries due to the good heat resistance, corrosion resistance and high specific intensity. Nevertheless, there are some problems during Ti alloy grinding, such as high processing temperature, strong chemical active type in the grinding zone, and serious grinding surface pollution. Therefore, reasonable grinding parameters are premise to assure surface quality and grinding efficiency of Ti alloy.
