Abstract:

In the light of the characteristic of 300M ultra high strength steel and the feature of orthogonal turn-milling machining,an optimization model of orthogonal turn-millng machining parameters is consisted of maximum tool life,minimum surface roughness and maximum productivity. Based on multi-objective optimazation algorithm which is applied in coupling particle swarm optimization algorithm and gray relevancy analysis,it can achieve the purpose which is above mentioned. By introducing the chatter stability lobe diagram of aircraft landing gear with orthogonal turn-milling which is conformed with DMG turn-milling machine tool,it can optimize the parameters of the orthogonal turn-milling machining of the aircraft landing gear with high efficiency and good quality.
