| Abstract: | Coronary artery stent is an important mechanical device designed to open arteries that have been occluded.In this paper,the processing techniques including output power,frequency,cutting speed,pulse width and assistant air pressure,which influence the quality of the coronary artery stent,have been studied with the fiber laser precision cutting system.The best processing techniques have been gained with the analysis and experiments.The high quality coronary artery stents have been cut with the output power of 7 W,pulse length of 0.15 ms,repeat frequency of 1500 Hz,scanning speed of 8 mm/s and oxygen gas pressure of 0.3 MPa. |
