摘要：
In this paper, a series of the surface machining experimentation using the cold air gun coolant system in the fine grinding process of Ti-6Al-4V titanium alloy was investigated for observing the machinability evaluation such as the quality of the ground surface, dimensions and shape precision. Meantime, the mathematical model was presented to model and analyze the machining parameters of the fine grinding process for the influences of the quality of the ground surface. A cold air gun coolant system was used in the experiments and produced a jet of compressed cold air in the air-cooling process during the metal grinding cutting process. Titanium alloys have found very wide application areas of aerospace, such as 3C industry, aviation industry, automotive, electric industry, medicine and dentistry due to their excellent corrosion resistance, lightweight, high fatigue strength, low thermal expansion, non-magnetismn, non-toxicity and mechanical properties. In this paper, the mathematical model was presented to model the machinability evaluation through the response surface methodology (RSM). The quadratic model of response surface methodology (RSM) associated with the sequential approximation optimization (SAO) method would be used to explain the relation of the finishing grinding process parameters and machining characteristic, and to find optimum values of machining parameters for the face cutting process of Titanium alloys.
