Carbon fiber reinforced plastic (CFRP) has been applied in aeronautics, aerospace, automotive and medical industries due to its superior mechanical properties. However, due to its difficult-to-cut characteristic, various damages in twist drilling and chip removal clog in core drilling could happen, inevitably reducing hole quality and hole-manufacturing efficiency. This paper proposes the wave-motion milling (WMM) method for CFRP hole-manufacturing to improve hole quality. This paper presents a motion path model based on the kinematics of the WMM method. The wave-motion cutting mode in WMM was analyzed first. Then, comparison experiments on WMM and conventional helical milling (CHM) of CFRP were carried out under dry conditions. The results showed that the hole surface quality of the CFRP significantly improved with a decrease of 18.1%–36% of Ra value in WMM compared to CHM. WMM exerted a significantly weaker thrust force than that of CHM with a reduction of 12.0%–24.9% and 3%–7.7% for different axial feed per tooth and tangential feed per tooth, respectively. Meanwhile, the hole exit damages significantly decreased in WMM. The average tear length at the hole exit in WMM was reduced by 3.5%–29.5% and 35.5%–44.7% at different axial feed per tooth and tangential feed per tooth, respectively. Moreover, WMM significantly alleviated tool wear. The experimental results suggest that WMM is an effective and promising strategy for CFRP hole-manufacturing.

碳纤维增强塑料孔的波动铣削可行性研究

碳纤维增强塑料(CFRP)由于其卓越的机械性能已被应用于航空,航天,汽车和医疗行业。然而,由于其难于切割的特性,在麻花钻中可能会发生麻花钻和切屑清除堵塞的各种损害,不可避免地降低了孔的质量和孔的制造效率。本文提出了一种用于CFRP孔加工的波动铣削(WMM)方法,以提高孔的质量。本文提出了一种基于WMM方法运动学的运动路径模型。首先分析了WMM中的波切割模式。然后,在干燥条件下进行了WMM和CFRP的常规螺旋铣削(CHM)的对比实验。结果表明,CFRP的孔表面质量显着提高,降低了18。与CHM相比,WMM中Ra值的1%–36%。与不同的CHM相比,WMM施加的推力要弱得多,对于不同的每齿轴向进给和每齿切向进给,WMM分别减小了12.0%–24.9%和3%–7.7%。同时,WMM中的孔出口损伤明显减少。在不同的每齿轴向进给量和每齿切向进给量的情况下,WMM孔出口处的平均撕裂长度分别减少了3.5%–29.5%和35.5%–44.7%。此外,WMM大大减轻了刀具磨损。实验结果表明WMM是CFRP孔制造的有效且有希望的策略。WMM中的孔出口损伤明显减少。在不同的每齿轴向进给量和每齿切向进给量的情况下,WMM孔出口处的平均撕裂长度分别减少了3.5%–29.5%和35.5%–44.7%。此外,WMM大大减轻了刀具磨损。实验结果表明WMM是CFRP孔制造的有效且有希望的策略。WMM中的孔出口损伤明显减少。在不同的每齿轴向进给量和每齿切向进给量的情况下,WMM孔出口处的平均撕裂长度分别减少了3.5%–29.5%和35.5%–44.7%。此外,WMM大大减轻了刀具磨损。实验结果表明WMM是CFRP孔制造的有效且有希望的策略。
