Fundamental Studies on High Power Fiber Laser Cutting Performance of 30 mm Thick Carbon Steel Plate

摘要：

An experimental investigation on the cutting performance of fiber laser assisted oxygen cutting (Flaox) for 30 mm thick carbon steel plate was performed. The effects of laser power, cutting speed, assist gas pressure and focal point position on the quality characteristics of Flaox cut were discussed. It was shown that by reasonable selection of the process parameters, clean cut surface with little dross and the maximum cutting speed for acceptable cut quality were obtained. Visual examination indicated that there existed an optimum combination of laser power, cutting speed and the assist gas pressure, while focal point position had a major effect on the surface roughness. In addition, it is essential to initiate and sustain the exothermic reaction of iron and oxygen at cutting front as well as remove the melt. This can be achieved by selecting sufficient laser energy and ensuring a wider kerf.
