  CO₂ laser beam was applied to the drilling process of high manganese cast steel. The average drilled diameter was investigated by changing the functions of the laser power, irradiation time, gas pressure and type of assist gases used. The average drilled diameter increased with the laser power and irradiation time. An average drilled diameter of 0.33mm could be obtained under the conditions : laser power of 400 W, irradiation time of 0.5 s, gas pressure of 0.5 kPa and oxygen as the assist gas. The roughness of the drilled surface increased with the cutting speed in laser beam drilling. The smoothest drilled surface for drilling of 2 mm in diameter obtained was 25 μm (Ry) under the conditions : 400 W, 300 mm/min and 294 kPa of oxygen as the assist gas. The laser beam drilling process of this cast steel did not generate a heat affected zone around the boundary between the base metal and drilled surface. These results show that CO₂ laser beam drilling serves as a new drilling process for high manganese cast steel, which reduces physical labor and improves working conditions in foundry industries.
