Інтелектуальна система контролю лазерного процесу з корекцією в реальному часі

Abstract

The paper presents an intelligent real-time monitoring and control system for laser processing based on frequency analysis of plasma optical emission. The correlation between keyhole stability and spectral characteristics of the emitted signal is applied to evaluate process quality. An ESP32-based hardware-software architecture performs signal acquisition, short-time Fourier transform processing, and calculation of a stability parameter for adaptive feedback control. Real-time correction of the laser beam focus position ensures stable penetration depth and improved weld quality. The proposed system enhances process stability, reduces defects, and enables integration into smart manufacturing environments.
