A method for cutting twin plates with a digital twin system of a laser cutting machine

Abstract

The invention discloses a method for cutting twin plates with a digital twin system of a laser cutting machine, which includes a base, a feeding mechanism, a cutting feed mechanism, an exhaust mechanism and a digital twin system, constructs a three-dimensional model corresponding to the physical cutting machine, and It is imported into the three-dimensional engine of the digital twin system; the digital twin system obtains the action data of the cutting machine in real time through the industrial Internet, and matches and debugs the three-dimensional model of the cutting machine based on the three-dimensional engine to complete the action, The state is synchronized with the real environment; the digital twin of the plate material is completed based on the virtual environment of the three-dimensional engine; the beneficial effect of the present invention: the heat generated by the cutting position is absorbed in time to prevent the plate from overheating and deformation; the state of the cutting machine is restored based on the digital twin, and the data The drive is synchronized with the real environment in real time, and the material generation is synchronized in real time; the real-time twin cutting material can be used for the verification of the material production plan and the detection and early warning of the production process.

Description

Technical field [0001] The present invention belongs to the field of cutting machine, and in particular to a method of cutting the twin sheet of a laser cutting machine and its digital twin system. Background technique [0002] The laser cutting is a cutting material using a high power density laser beam, so that the material is quickly heated to a vapor temperature, evaporated to form a hole, with the movement of the beam to the material, the hole continuously forms a narrow slit, complete the material Cutting, laser cutting is to irradiate the workpiece with the focused high power density laser beam, so that the illuminated material is rapidly melted, vaporized, ablated or reaches the combustion point while blowing out the melt substance with the high-speed air flow coaxial with the beam, thereby achieving The workpiece is cut. The laser cutting machine has the characteristics of high precision, fast cut, good effect, and will gradually replace some traditional cutting process ...
