Abstract

The invention discloses a laser cutting machine and a method for cutting twin plates through a digital twin system thereof. The laser cutting machine comprises a base, a feeding mechanism, a cutting feeding mechanism, an air draft mechanism and the digital twin system, a three-dimensional model corresponding to an entity cutting machine is constructed, and the three-dimensional model is guided into a three-dimensional engine of the digital twin system; the digital twin system obtains action data of the cutting machine in real time through the industrial internet, the three-dimensional model of the cutting machine is matched and debugged based on the three-dimensional engine, and the action and state of the three-dimensional model of the twin cutting machine are synchronized with the real environment; digital twin of plate materials is completed based on a virtual environment of the three-dimensional engine; the laser cutting machine has the beneficial effects that heat generated at the cutting position is absorbed in time, and plate deformation caused by overheating is prevented; based on digital twin, the state of the cutting machine is restored, data driving and the real environment are synchronized in real time, and material generation is synchronized in real time; and real-time material twin cutting is achieved, and the machine can be used for verification of a material production scheme and detection and early warning in the production process.

Description

technical field [0001] The invention belongs to the technical field of cutting machines, and in particular relates to a laser cutting machine and a method for cutting twin plates by a digital twin system thereof. Background technique [0002] Laser cutting is the use of high-power-density laser beams to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and evaporates to form holes. As the beam moves to the material, the holes continuously form narrow slits to complete the cutting of the material. Cutting, laser cutting is the use of a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, and at the same time the molten material is blown away by the high-speed airflow coaxial with the beam, so as to achieve The workpiece is cut open. Laser cutting machine has the characteristics of high precision, fast cuttin...
