Interaction between Micro-Amplitude Vibration and Thrust Force in Ultrasonic-Vibration-Assisted Drilling of Glass-Fiber-Reinforced Plastics

This research intends to investigate the effect and potential of ultrasonic vibration tools for drilling glass-fiber-reinforced plastics (GFRPs), especially with aim minimizing thrust force. As an important parameter characterize intensity, amplitude has a significant on force in ultrasonic-vibration-assisted (UVD) GFRPs. It been observed that also influences amplitude, which may eventually result failure vibration. In this study, method in-process measurement was introduced enable investigation interaction between UVD. investigated how variations influence each other from holistic individual perspectives. The critical condition identified ensure sufficient during drilling. Additionally, UVD experiments different amplitudes were carried out. revealed. can be concluded combination moderate force, low reduction ratio, high increases ratio secondly excessive undermines provides in-depth understanding UVD, helps further improve
