摘要:
以玻璃纤维增强树脂基复合材料及其复合构件台阶孔为研究对象,通过性能分析、工装和刀具设计、工艺参数优化等研究加工中各因素对台阶孔的影响。实验结果表明,采用镶合金复合钻头25°(螺旋角p)/15°(后角α),使用专用的工艺装置给钻削区材料施加预压应力,钻头转速为250、315 r/min、进给量为0.06、0.1 mm/r时,孔的加工质量达到最优。

Abstract:
Takes glass fiber reinforced resin matrix composite and its composite stepped hole as the research objects, through performance analysis, tooling and tool design, process parameters optimization, the influence of various factors on the stepped hole is studied. The experimental results show when the pre pressure stress is applied to the material of the drilling area by using the 25 degree (helix angle)/15 degree (rear angle) of the alloy composite bit, the processing quality of the hole is best under the speed of the bit is 250 or 315 r/min, the feed rate of the bit is 0.06 or 0.1 mm/r.
