Theoretical analysis and experimental research on the pressing force of robot drilling CFRP sheet

In the process of drilling CFRP sheets by industrial robots, contact stiffness between terminal actuator and sheet is poor, which causes hole position to vibrate during processing. The design a presser foot device in front can effectively solve this problem. Navier method used allowable range pressing force foot. A numerical simulation model for established, influence different forces within on quality studied, recommended value obtained. Drilling experiments are carried out under forces. experimental results show that optimized reduce vibration process, surface roughness wall reach 1.8 μm. At same time, morphology at exit machined improved.
