Taking carbon fiber reinforced matrix composite(CFRP)as the processing object,a comprehensive experiment project of high efficiency and low carbon drilling was designed.By using the response surface method,the effects of spindle speed,feed speed and CFRP sheet laying sequence on the processing quality of CFRP components are studied.A predictive regression equation is established,and the process parameters of optimal orifice quality and lowest power consumption are finally obtained:The optimal layup sequence is[0°,90°,0°,90°],the spindle speed is about 2 000 r/min,and the feed speed should be set at about 50 mm/min to get the lowest power;the spindle speed is at 10 000 r/min,feed speed should be set at about 20 mm/min to get the lowest hierarchical factor.The experimental process includes CNC machining,data analysis and model building,and involves many disciplines such as new material processing,green processing and energy saving and carbon reduction,which can enhance students'scientific research interest,practical ability and innovation awareness.
