Abstract Machining damage incurred in milling carbon fiber reinforced polymer (CFRP) composite is closely related to the cutting force. However, the dynamic distribution of the cutting force arising from different cutting effects has not been fully investigated. In this study, a new two-region cutting model was used to analyze components of the cutting force resulting from the cutting and edge effects in the milling of CFRP. The friction coefficient was obtained as a function of the fiber cutting angle. The instantaneous magnitudes of the net cutting, pressing and friction forces were identified quantitatively. The variation of different force components and the corresponding specific cutting energies were studied in relation to the cutting mechanisms. The relationship between the cutting forces and machining damage was also investigated. A mechanistic milling force model is proposed. Comparison indicates that the model can produce better prediction of the milling force than the traditional model.

考虑边缘效应的碳纤维增强聚合物复合材料铣削切削力分析

摘要 碳纤维增强聚合物（CFRP）复合材料铣削加工过程中产生的切削损伤与切削力密切相关。然而，由于不同切削效果而产生的切削力的动态分布尚未得到充分研究。在这项研究中，一种新的两区域切削模型用于分析由切削和边缘效应在 CFRP 铣削中产生的切削力分量。摩擦系数是作为纤维切割角的函数获得的。定量确定净切割力、压力和摩擦力的瞬时大小。研究了与切削机制相关的不同力分量的变化和相应的特定切削能量。还研究了切削力与加工损伤之间的关系。提出了一种机械铣削力模型。比较表明，该模型比传统模型能更好地预测铣削力。
