摘要/Abstract

摘要： 通过分析碳纤维增强复合材料螺旋铣制孔过程的分层机理，提出一种基于经典板壳理论的用于解析复合材料螺旋铣孔出口分层的临界轴向力模型.模型分析表明，螺旋铣孔过程剩余的未切削材料厚度是影响材料出口分层的重要因素；随着未切削材料厚度的减小，材料发生出口分层的概率增加.开展了复合材料螺旋铣孔实验研究，结果显示，模型轴向力临界值最大偏差为13.48%.全因子实验结果显示，轴向力随着主轴转速的增加而降低，随每齿进给量的增加而增加，随每转轴向切深的增加而增加；刀具磨损与轴向力大小呈线性关系，当每齿进给量为0.02mm/齿、主轴转速为6000r/min、每转轴向切深为0.1mm/r时材料所受轴向力最小.

Abstract: Through a delamination mechanism analysis in the helical milling of carbon fiber reinforced polymers(CFRP)， a critical axial force model is put forward based on the classic theory of plates and shells， which is used to resolve the exit delamination state.The model analysis shows that the thickness of the uncut material is an important factor affecting the material’s exit delamination in the helical milling process， and with the decrease of the thickness， the probability of exit delamination increases. Experimental study on the helical milling of CFRP is carried out， and the results show that the maximum deviation of the critical axial force of the model is about 13.48%. The full-factor experimental results show that the axial force decreases with the rise of the spindle speed， increases with the rise of the feed per tooth， and increases with the rise of the axial cutting depth per revolution. The tool wear has a linear relationship with the axial force. Under the conditions of 0.02mm/t feed per tooth， 6000r/min spindle speed and 0.1mm/r axial cutting depth per revolution， the axial force is the minimum.
