| 摘 要： | PCB用硬质合金钻头是一种形状复杂的带螺旋槽的微孔加工工具,由传统的麻花钻衍生而来.微钻的结构参数与切削刃的切削性能密切相关,这些参数之间相互联系、相互影响.本文通过定义旋转矩阵建立了整体坐标系下微钻的后刀面数学模型,以向量形式推导了相应的横刃斜角和切削刃的数学表达式,定量分析了影响其切削性能的结构参数,得出相关结论,...

| Abstract: | The carbide drills for printed circuit boards,which are derived form conventional twist drills,are microholes drilling tools with complex helical flutes.The relationships between the structural parameters and the cutting performances are closely related,and the structural parameters are related to each other and influencing each other.In this paper,the mathematical model of flank surfaces of microdrill in the global coordinate system is established by defining the rotation matrix,and the related mathematica... |
