Influence of cryogenic temperature on machining mechanisms and surface integrity of CF/PEEK composites based thermo-mechanical coupling analysis

Key Points

• Surface integrity improved significantly at cryogenic temperatures, leading to enhanced durability.
• Machining mechanisms are altered by cryogenic temperature, optimizing the cutting process at lower thermal expansion rates.
• Thermo-mechanical coupling analysis was used to investigate how such temperatures affect material interactions during machining.
• Findings support the potential for better fabrication methods in composite materials, aiming for higher precision.
