摘要
以碳纤维增强基复合材料(CFRP)为加工对象,设计了一种高效低碳钻削加工的综合实验项目。基于响应曲面法研究了机床主轴转速、进给速度和CFRP板材铺层顺序对CFRP构件加工质量的影响,建立了预测回归方程,最终得出最优孔口质量和最低功耗的工艺参数:最佳铺层顺序为[0°,90°,0°,90°],主轴转速在2000 r/min左右,进给速度设置在50 mm/min左右时功率最低;主轴转速在10000 r/min左右,进给速度设置在20 mm/min左右时分层因子最低。实验涉及新型材料加工、绿色加工和节能降碳等多个学科领域,能够增强学生的科研兴趣,提高实践动手能力和创新意识。
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 2000 r/min,and the feed speed should be set at about 50 mm/min to get the lowest power;the spindle speed is at 10000 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.
