AI Technical Summary

Problems solved by technology

However, the current device using laser-driven flyer micro-forming technology cannot continuously pulse laser-driven flyer micro-forming, and its mass production is only the forming of multiple dies under one pulse impact, which is not a rapid and continuous mass production in the true sense. Production, and because the workpiece and fixtures need to be re-clamped after a laser shock forming in this device and method, it is bound to bring human errors due to manual operations and affect the processing accuracy

Moreover, the open laser light path also has certain potential safety hazards
