Cutting-Edge Innovations in Precision Machining and Forming Technology

Dear Colleagues,

Driven by global trends of intelligent, green, and high-precision development in manufacturing, precision machining, and forming, technologies have become core enablers in strategic industries such as the aerospace, high-end equipment, and new energy industries. To address challenges in complex component processing, difficult-to-cut material forming, and high-efficiency manufacturing demands, this Special Issue focuses on advanced design methodologies, intelligent control technologies, and interdisciplinary process innovations, aiming to drive groundbreaking advancements in precision manufacturing theory and practice.

Key topics include the following:

• Precision Equipment Design and Control: Structural optimization of precision machine tools, servo control system development, fluid-power system performance
• Intelligent and Green Manufacturing Technologies: Intelligent status monitoring with IoT and digital twin, energy consumption monitoring, energy-saving strategies, and multi-physics collaborative simulation.
• Ultra-Precision Machining Processes: Ultrasonic vibration-assisted cutting, multi-energy-field composite machining, micro-/nano-scale surface integrity control, tool wear, and efficient machining of difficult-to-cut metals.
• Advanced Forming and Material Processing: Stamping and forming mechanisms, fine blanking processes, wear mechanisms, and lifespan prediction of ultra-hard tools.
• Quality and Reliability: Intelligent compensation of machining errors, real-time detection of micro-defects, surface/subsurface optimization.

This Special Issue encourages original research addressing key challenges in the precision industry, covering process mechanisms, equipment development, and industrial application cases, with a view towards higher-accuracy precision manufacturing, lower energy consumption, and enhanced intelligence.
