Study on Drilling Force and Surface Defects of GFRP/Aluminum Alloys Laminated Structure
Glass fiber reinforced plastics(GFRP)is widely used in aerospace manufacturing with the excellent prop-erties such as light weight,high specific strength and corrosion resistance.In order to study the axial force and delamination characteristics of GFRP/aluminum alloy laminated,the drilling experiments are carried out.The influence of spindle speed and feed speed on the drilling force and delamination characteristics of GFRP/aluminum alloy laminated structure is stud-ied.The experimental results show that the drilling force decreases with the increase of spindle speed,and the drilling force increases with the increase of feed speed.An empirical model of the drilling force is established,the error between the measured and theoretical values is controlled within3%,which provides a theoretical basis for predicting the drilling force.The lower the spindle speed and the higher the feed speed,the more obvious the stratification characteristics.High speed and low feed are conducive to reducing delamination and improving processing quality.
