The advancement of high-speed, high-performance cutting technology has significantly elevated the standards of aircraft manufacturing. This innovation plays a vital role in efficiently and accurately machining difficult materials like titanium alloys, which are commonly used in aerospace applications. Titanium alloy cutting is not just about having advanced machines or tools—it involves a comprehensive system that includes optimized cutting parameters, suitable tool-workpiece combinations, and effective cooling and lubrication techniques.
High-speed cutting has become a major focus for industrialized nations, especially in Europe and America. According to a 2001 report by the Rand Corporation, high-performance cutting technology for materials like titanium was identified as one of the core technologies in modern aircraft manufacturing. Researchers around the world have explored various aspects such as machine tools, cutting media, and process optimization to improve efficiency and reduce costs.
Despite significant progress, challenges remain. High-speed cutting of titanium alloys often leads to rapid tool wear, increasing costs and reducing efficiency. To address these issues, scholars have conducted extensive research on new tool materials, improved cooling methods, and better understanding of tool wear mechanisms. Some promising developments include the use of super-hard materials like polycrystalline diamond (PCD) and cubic boron nitride (CBN), which allow for higher cutting speeds but come with higher costs and vulnerability to breakage.
In addition, new tool designs—such as variable helix cutters and wave-shaped rake faces—have been introduced to reduce vibration and improve stability during machining. However, these designs can be complex to manufacture and may not fully solve the issue of tool wear. Optimizing tool geometry and surface texture remains an ongoing challenge.
Current research continues to focus on understanding the thermo-mechanical effects during titanium alloy cutting, improving tool-life, and enhancing overall cutting efficiency. These efforts are essential for advancing the future of aerospace manufacturing.
