Study on efficient machining technology of titanium alloy rudder core

The rudder core assembly is made of titanium alloy, which is difficult to process. The whole rudder core skeleton and the skin of the rudder core are welded together. The shape is a wedge structure composed of spatial composite surfaces. For multiple types of rudder core processing in the process of repeatedly clamping, alignment, measurement and cutting processing cycle is long and low machining efficiency, through the study of the mechanism analysis of machining method, from the combination of the design of general equipment, improve the processing process and three aspects, the reasonable choice cutting tool parameters for efficient processing technology research, shorten the processing cycle of the rudder core products, Further improve the stability of product processing quality.

Rudder core is an important part in the structure of aerospace vehicle, which plays an important role in controlling flight attitude. Therefore, its machining accuracy directly affects the flight accuracy of products. Titanium alloy rudder core has been widely used in aerospace field due to its advantages of light weight and high stiffness. However, due to the high hardness of the material, low thermal conductivity, and the product structure is complex, not easy to clamp, in the processing process of local residual removal and easy deformation, it is difficult to ensure high precision requirements. In order to ensure the machining accuracy of parts, the traditional technology adopts the method of repeated machining, resulting in many processing procedures and long production cycle, which can not meet the production demand.
