Abstract
CFRP/Ti laminates are widely used in critical parts such as aircraft skin and wings because of their excellent material properties. However, the common problem of the two materials is that they are difficult to process and the surface quality of the parts is poor. In this paper, the experimental study of milling CFRP/Ti laminate with diamond coated element edge tool was carried out. By combining theoretical analysis with experimental method, the variation law of cutting force and surface morphology of CFRP/Ti laminate under different cutting parameters was obtained. The results show that the cutting force decreases with the increase of spindle speed and the decrease of feed speed; With the milling process, the maximum increase rate of cutting force reaches 160%, the minimum increase rate is 20%, and the cutting force fluctuates greatly. Large areas of resin coating and groove area appear in CFRP processing area, while obvious vibration marks and scratches appear in titanium alloy processing area, and the surface quality has gradually deteriorated.
