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.
