| 摘 要： | 文摘凯夫拉纤维增强复合材料(KFRP)在钻削过程中会产生严重的分层、起毛等缺陷,难以满足装配工序的要求。本文将螺旋铣削工艺运用于KFRP复合材料制孔,进行了偏心距、主轴转速和刀具类型的单因素试验,以分层因子、起毛面积和孔径偏差表征KFRP复合材料螺旋铣削的制孔质量,深入研究不同工况下的缺陷抑制机理和制孔质量。结果表明,偏心距、主轴转速和刀具结构对制孔质量均有显著影响,采用波形四刃铣刀在偏心距0.5 mm和主轴转速4 000 r/min工况下的制孔质量最好,分层因子和孔径偏差分别为1.27和1.2%,起毛面积比二刃铣刀下降了13.7%。

| Abstract: | Delamination and fuzzing defects during drilling of KFRP composites are too severe to meet the requirements in assembling process. Therefore, orbital drilling is proposed to drill KFRP composites in this study. Single factor experiments are conducted to investigate the hole quality and inhabitation mechanisms in different working conditions. Delamination factor, fuzzing area and diameter deviation are presented to characterize the hole quality. The experimental results indicate that there are close influences of eccentricity, spindle speed and cutter geometry on hole quality. When four-flute end mill with waved edges is used, hole quality is the best in working condition of e=0.5 mm and N=4 000 r/min. The delamination factor and diameter deviation are 1.27 and 1.2% respectively, and reduction of fuzzing area from drilling with two-flute end mill is 13.7%. |
