Abstract

The invention discloses an anti-fatigue efficient milling parameter optimization control method for a titanium alloy thin-wall component. The method comprises the following steps that: establishing the primary election technological parameter domain of a titanium alloy thin-wall component; carrying out an orthogonal test; testing the surface integrity parameter of a test component; establishing acharacteristic relational expression of a titanium alloy thin-wall component milling technological parameter and surface integrity; according to the relational expression of the titanium alloy thin-wall component milling technological parameter and the surface integrity, a target function and a milling technological parameter constraint condition, establishing an optimization model for the anti-fatigue efficient milling parameter of the titanium alloy thin-wall component; and through an optimization tool in MATLAB, solving the optimization model for the anti-fatigue efficient milling parameterof the titanium alloy thin-wall component to obtain the anti-fatigue efficient milling parameter of the titanium alloy thin-wall component. By use of the method, the problems of poor surface integrity characteristic and low material removal rate in a milling process of the titanium alloy thin-wall component are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of anti-fatigue precision cutting and processing, and in particular relates to a parameter optimization control method for anti-fatigue and high-efficiency milling of titanium alloy thin-walled components. 【Background technique】 [0002] Titanium alloy materials have excellent mechanical properties, low density, high specific strength, corrosion resistance, high and low temperature resistance, and are another important structural material after steel and iron. A variety of information and data show that the use of titanium alloys instead of steel materials in aircraft engines can reduce the weight of the engine structure by 30% to 40%. Therefore, titanium alloys are widely and widely used in the manufacture of aircraft engines and airframes, which can effectively improve the thrust-to-weight ratio of the engine and the efficiency of the airframe mechanism, and help alleviate the thermal barrier phenomenon....
