The rapid development of the aerospace industry has increased the demand for titanium alloy integral structural parts. However, the extremely high material removal rate, thin-walled complex shape and difficult-to-machine characteristics of titanium alloy integral structural parts give such parts high quality, High-efficiency machining of titanium workpieces has brought huge challenges.
At present, my country’s aerospace industry has entered a stage of rapid development, and the application range of aerospace technology has become wider and wider. The market demand is showing a rapid growth trend. Fast and low-cost launch, long-term flight in orbit, high maneuverability, high payload, etc. An urgent need for the development of the aerospace industry. Faced with this demand, high-strength, low-density materials, integrated, thin-walled parts structures, and high-efficiency, low-cost, energy-saving and environmentally-friendly processing methods are becoming key technical features of advanced aerospace manufacturing technology.
Advanced materials are the technical basis for aerospace products to achieve the desired technical performance, service life and reliability. Currently, aerospace materials mainly use aluminum-magnesium alloys, titanium alloys, high-strength steels and composite materials, and the use of titanium alloys in aerospace structural parts continues to increase.
High-performance titanium alloy has the characteristics of high specific strength and specific stiffness, low density, good corrosion resistance and superior fatigue resistance. It is a typical representative of the application of new materials in the aerospace industry to achieve the desired technical performance, service life and reliability. . Titanium alloy can work reliably under extreme conditions such as ultra-high temperature, ultra-low temperature, high vacuum, high stress, and strong corrosion. It is known as "cosmic metal" and has a wide range of applications in the aerospace industry. Titanium alloys account for 5% to 30% of the mass in launch vehicles and are also widely used in spacecraft such as "Peace-1", "Progress", "Venus" and "Moon".
Titanium alloy and structural integration have the aforementioned significant advantages, but the poor performance of titanium alloy processed parts combined with the structural complexity and high material removal rate brought about by structural integration brings great challenges to the processing of titanium alloy parts, which is a great challenge for manufacturing equipment. , Process technology, etc. put forward very high requirements.
