摘要

对以轴向钻削力为监测对象的微孔钻削在线监测进行了研究。以50支直径为0.4mm的高速钢麻花钻为样本

在数控高速精密微孔钻床上

对钻削45#碳素钢时微钻头折断的轴向钻削力极限值进行了检测。经参数估计和统计检验

得到轴向钻削力极限值服从对数正态分布的结论

并建立了基于可靠性的轴向钻削力监测阈值的确定方法。在此基础上选取不同可靠度水平进行了在线监测实验

与普通钻削比较

当选取可靠度水平为0.999时

在钻头利用率相同的情况下

10支钻头的折断率由30%下降到0

为避免发生微钻头折断这一长期困扰微孔加工的技术问题提供了一种良好的工艺方法。

Abstract

With 50 HSS twist drills of 0.4 mm in diameter used as samples on a CNC high speed precise drilling machine

limit thrust values of micro drill breaks were examined while No.45 carbon steel was drilled. It is concluded from parameter evaluation and statistics that the limit thrust values obey the logarithm normal distribution law. The way of monitoring the threshold of thrust was also developed using the reliability theory. Experimental on-line monitoring was run at different reliable levels. When the reliable level selected was 0.999 and the drill utilization ratio was the same as that of in ordinary drills

the drill break ratio of 10 drills decreased from 30% to 0.
