Simulation of Drilling on the Copper of PCB with Ultra-High-Speed
This paper gives an introduction of the simulation of ultra-high-speed drilling on the copper of printed circuit board (PCB) by using finite element method (FEM). The cutting force, cutting torque and the distribution of cutting temperature are predicted. The value of cutting force is also be compared with the experimental value. The simulation results show that the experimental value of cutting force agrees well with the FEM value and the value of cutting torque is very small in the drilling process , in addition，the maximum temperature of copper comes up to 209 °C in center area and the temperature of copper chip evacuation from the spiral groove ranges from 135°C to 155 °C.
