摘要

碳纤维增强复合材料（CFRP）具有跨尺度、多相等结构特点，呈现显著的各向异性和不均匀性，加工性能差，容易出现明显的毛刺和分层。为了分析CFRP 螺旋铣孔特性，采用球头铣刀针对CFRP 开展了螺旋铣孔工艺技术的研究，着重对切削力、刀具磨损和制孔质量进行了详细分析。首先基于试验结果分析了径向切削力、轴向切削力以及切削温度随切削参数变化而变化的状况，接着分别从侧刃和球面的角度对刀具磨损进行了研究，最后根据制孔深度分析了制孔直径的变化，同时分析了制孔入口和出口的质量情况，并采用分层因子描述了制孔入口的分层情况。结果显示，球头铣刀在CFRP 螺旋铣孔过程中具有较好的切削特性，但制孔质量还有待提高。

Abstract

Carbon fiber reinforced polymer (CFRP) has the characteristics of multi-scale and multi-equal structure

showing significant anisotropy and heterogeneity

poor machining performance

and easy to appear obvious burrs and delamination. In order to analyze the characteristics in helical milling of CFRP

the ball helical milling of CFRP was studied

and cutting forces

tool wear and hole-making quality were analyzed in detail. First

based on the result of the experiment

the changes of axial and radial cutting force and cutting temperature over cutting parameters were analyzed. Then

tool wear was studied respectively from the lateral edge and spherical edge. Finally

hole diameter was analyzed from the perspective of the hole deep

entry and exit hole-making quality

and delamination factor was used to describe entry delamination state. The results show that the ball end milling cutter has better cutting characteristics in the ball helical milling of CFRP

but hole-making quality needs to be improved.
