Description

technical field [0001] The invention belongs to the field of laser processing systems, and more specifically relates to a galvanometer-type laser scanning large-format material forming and processing control system. Background technique [0002] Galvanometer-type laser scanning processing is an advanced processing method with high precision and high efficiency. It uses the interaction between high-energy beams and materials and the terminal effector (scanning head) with excellent servo performance to shape and process various materials. Its typical applications include 3D printing forming, laser marking, laser welding, laser cutting, etc. The galvanometer scanning head is composed of a servo motor with a limited rotation angle and the lens on the motor shaft. A single set of two-dimensional galvanometer laser scanning system includes 2 scanning heads. The main disadvantage of this processing method is that the scanning area of ​​a single laser scanning system is limited. ...
