[0002] Steep pulse perforation ablation emergency stop energy release control system belongs to the field of manufacturing technology, which covers everything from traditional metal processing to modern high-end manufacturing processes, with engine manufacturing being a key application. In these applications, the implementation of micro-hole processing technology is crucial, mainly used to improve the performance and efficiency of key components such as turbine blades. In order to achieve precise material removal, pulse perforation technology, as an innovative method, uses high-frequency, high-energy laser pulses to quickly and accurately punch holes in materials, meeting the requirements of modern engineering for complex geometries and strict tolerances.

[0003] Although pulse perforation technology has been widely used in high-precision manufacturing at this stage, it still faces many challenges in the actual processing process. One of the most prominent problems is the overheating of the material caused by heat accumulation, which leads to a decrease in processing accuracy or even material damage. Traditional control systems usually rely on fixed processing parameters and lack the ability to monitor and dynamically adjust the processing process in real time.
