印刷电路板或PCB由通常由薄铜箔制成的导电层和层压在一起的绝缘层组成。通过PCB的孔通常是用固体碳化钨制成的微小钻头钻的。本文主要研究钻孔PCB的切削力。研究了切削速度、进给量和钻头直径对推力的影响。最后推导出钻削力经验公式的数学模型。
A printed circuit board or PCB consists of conducting layers typically made of thin copper foil and insulating layers laminated together. Holes through a PCB are typically drilled with tiny drill bits made of solid tungsten carbide. This paper focuses on cutting forces of drilling PCB. The influences of cutting speeds, feed rate and drill diameter on thrust force are investigated. Finally the drilling force experimental formula’s mathematical model is derived.
