Control of ultrasonic surface rolling process machine tool for aero-engine blades

2018 15th International Conference on Control, Automation, Robotics and Vision (ICARCV), 2018
The surface quality of blades affects the performance and security of aircraft engines. Ultrasonic surface rolling process (USRP) can be used to improve service life of alloys. However, blades with complex design specifications are difficult to processing, especially the thin-walled leading/trailing edge should bear the loads during the process of ...

Enhanced Surface Mechanical Properties of Cr12MoV Using Ultrasonic Surface Rolling Process and Deep Cryogenic Treatment

Solid State Phenomena, 2018
Ultrasonic surface rolling process (USRP) combined with deep cryogenic treatment (USRP+DCT) was applied on quenched and tempered Cr12MoV. The results indicated that USRP and USRP+DCT could significantly improve the surface mechanical properties, leading to smaller surface roughness and smoother morphology with less cracks and defects.
