With the advancement of global carbon emission reduction strategies and the rapid development of the aerospace industry, high-strength, heat-resistant difficult-to-cut materials (such as nickel-based superalloys, titanium alloys, ceramic matrix composites, etc.) have become core materials for critical components like aero-engine parts and spacecraft structural components. However, these materials exhibit high hardness, high toughness, and low thermal conductivity, making them typical difficult-to-cut materials. Traditional machining technologies face challenges such as excessive cutting forces, high cutting temperatures, severe tool wear, and poor surface integrity, which severely constrain machining efficiency and component service performance.
In recent years, multi-energy field-assisted machining technologies (e.g., ultrasonic vibration, electrostatic atomization, magnetic field modulation) have demonstrated significant advantages in reducing cutting forces, improving heat dissipation conditions, and suppressing machining defects through energy coupling and dynamic regulation mechanisms. To further promote innovative applications of these technologies in aerospace manufacturing, this special issue focuses on interaction mechanisms between multi-energy fields and difficult-to-cut materials, process optimization, and sustainability enhancement, soliciting cutting-edge research and technological breakthroughs to advance aerospace manufacturing toward high performance, low energy consumption, and high precision.
