The study of Quality Monitoring and Control for Laser Cutting based on pulse-induced acoustic sound
In this paper,the pulse-induced acoustic sound in laser curing is collected,and the data processing is performed with wavelet denoising and time-frequncy analyzing.The impact of laser processing parameters on the acoustic signal is discussed; and further analysis of the effect of cutting speed is conducted.The corresponding relationship between the best velocity and the maximum time-frequency energy density is got; also the plan of adaptive control in laser cutting is designed.The results in this paper can provide important parameters for adaptive control of laser cutting.
