In order to explore the clean machining rule of titanium alloy, cutting parameters for tests were schemed out by using the uniform design method. And cutting tests were conducted under the condition of dry cutting and cold blast machining respectively. Through the regression analysis about the test results, a multiple quadratic regression model was established. And an empirical formula of cutting force and surface roughness was derived through the optimal subset method and custom variable method towards the model,which was applicable for titanium alloy finishing machining. The variance analysis about the formula shows that it is of remarkable linear relationship. Comparing and analyzing the characteristic relation among the cutting force, surface roughness and the cutting parameters under the conditions of dry cutting and cold blast machining, and it shows the latter one is more applicable for efficient finishing machining of titanium alloy. A cardinal principle for the selection of cutting parameters for titanium alloy finishing machining was also put forward.
