Paper Abstract

In this paper, a laser cutting technology for the oil pipes with the thickness of 10mm, the diameter of 142mm and the material of N80 has been developed, in order to reduce the high hole-blast rate in processing. Experiments are taken on the Rofin DC025 slab CO2 laser cutting system and a set of flexible fixtures. The reasons of forming blast-hole have been analyzed, and the influences of technique parameters on blast-hole rate have been studied, such as laser power, pulse frequency, laser delay, focus position and oxygen pressure. The results show that the blast-hole rate can be controlled lower than 5% at the conditions of laser power 1500W, laser delay 5s, pulse frequency 180Hz, the oxygen pressure 0.6 kg/cm2, focus length 190mm, nozzle diameter 1.5mm.
