摘要/Abstract

摘要： 在碳纤维复合材料的制孔加工中,微孔加工是一项重要的加工技术。微孔加工中的分层现象主要是由入口钻头的剥落效应和出口的推挤效应引起的。孔壁损伤主要由钻削温度过高导致层间树脂软化、粘刀,影响刀具切削质量。本文通过实验研究了不同主轴转速和进给速度对直径为1 mm的碳纤维复合材料孔的轴向力和钻削温度的影响,并用扫描电镜(SEM)观察了微孔质量。结果表明,控制主轴转速和进给速度可以有效地降低轴向力和层间温度,提高成孔质量。

Abstract: In the hole-making process of carbon fiber composites, micro-hole processing is an important processing technology. The delamination in micro-hole machining is mainly caused by the spalling effect of the inlet bit and the pushing effect of the outlet. The damage of hole wall is mainly caused by too high drilling temperature, which leads to the softening of interlayer resin and adhesion of the cutter, and affects the cutting quality of the cutter. In this paper, the effects of spindle speed and feed speed on axial force and interlaminar temperature of carbon fiber composites with a diameter of 1 mm were studied experimentally, and the micropore quality was evaluated by SEM. The results show that controlling spindle speed and feed speed can effectively reduce axial force and interlayer temperature and improve the quality of hole forming.

Key words: CFRP, micro-hole, axial force, drilling temperature
