Study on interaction between vibration amplitude and thrust force in ultrasonic drilling of glass fiber-reinforced plastics(GFRPs)
This research intends to investigate the effect and potential of ultrasonic vibration of tools for drilling glass fiber-reinforced plastics(GFRPs),especially with the aim of reducing thrust force and delamination.As an important parameter to characterize the vibration intensity,the set vibration amplitude has a significant effect on thrust forcein ultrasonic assisted drilling(UAD)of GFRPs.It has been observed vice versa that the thrust forcealso influences the vibration amplitude,which may eventually result in a failure of the vibration.In this study,a method for in-process measurement of the vibration amplitude has been introduced to enable the investigation of the interaction between the vibration amplitude and thrust force in drilling.It has been investigated how variations of the vibration amplitude and thrust force influence each other,and the critical condition has been identified to ensure a sufficient ultrasonic vibration effect during the drilling process.Besides,UAD experiments with large vibration amplitude and small vibration amplitude have been carried out,and the effect of the vibration amplitude on the thrust force has been revealed.It can be concluded that the combination of high vibration amplitudes,low vibration amplitude reduction ratio will facilitate the reduction of thrust force and secondly that an excessive thrust force will undermine the effect of ultrasonic vibration.
