Laser power has important influence on the cutting quality,and the burning defect is easy to happen if the laser power is too high.In order to guarantee the cutting quality,a real-time power control method based on programmable multiple axes controller was presented to study the relationship between laser power and cutting speed.The analysis of laser cutting test shows that burning defect can be avoided when laser power can change with the cutting speed, the cutting quality can be improved effectively by this method,and efficiency of laser cutting is guaranteed.
