摘要:

为了准确预测多向铺层碳纤维增强聚合物(CFRP)复合材料在螺旋铣孔过程中的切削力,基于多向CFRP的材料特点和螺旋铣孔的加工原理,考虑不同纤维铺层螺旋铣孔层间效应,分析纤维方向角对切削力的影响;根据不同切削区域受力情况计算微元切削力,通过叠加原理建立了多向铺层复合材料螺旋铣孔切削力模型.并开展了多向CFRP螺旋铣孔试验,对试验测得的切削力进行滤波处理后进行分析,根据试验数据标定层间效应系数,将试验测得的切削力与模型预测的切削力进行比较.结果显示:X,Y向切削力最大误差不超过20%,Z向切削力最大误差不超过10%,试验结果验证了模型的正确性.

Abstract:

In order to accurately predict cutting forces during helical milling of multi-directional layup carbon fiber reinforced polymer(CFRP) composites, the characteristics of multi-directional CFRP material and the principle of helical milling were analyzed, and the interlayer effects among different fibers of helical milling were considered, the influence of fiber orientation angle on cutting forces was explored. Based on the force conditions in different cutting regions, the microelement cutting force was calculated using the superposition principle, and the cutting force model in helical milling of multi-directional layup composite material was established. Helical milling experiments on multi-directional CFRP were carried out, and the measured cutting force after filtering by the experiment was analyzed. According to the experimental data, the interlayer effect coefficients were calibrated, and experimentally measured cutting forces were compared with the predicted one by the model. The results show that the maximum error of X and Y directional forces is less than 20% and the maximum error of Z directional force is less than 10%, which verifies the correctness of the model.
