Problems solved by technology
[0003] The calibration method for debugging the existing laser cutting control system is relatively simple. It is mainly transferred from 2D cutting to 3D cutting. Various incompatibility problems will appear in long-term use, and its calibration method is relatively simple. Rough, linear division only by calibrating the height of two points
And because the calibration method of 2D cutting is used, its stability in 3D cutting is insufficient, and the compatibility is not good

The invention discloses a control system based on three-dimensional five-axis 3D laser cutting. The control system comprises a numerical control system, a cutting head and multiple drive motors. The numerical control system controls all the drive motors to rotate and comprises a demonstrator and a controller. The cutting head comprises a spraying nozzle. The spraying nozzle is provided with a metal induction chip. The metal induction chip and a cutting panel cut form a capacitor. The metal induction chip is connected with the controller. The controller judges the distance between the metal induction chip and the cutting panel cut according to feedback voltage of the metal induction chip. The demonstrator sets the distance between the metal induction chip corresponding to the feedback voltage and the cutting panel cut through multi-point calibrating. By means of the controller, the demonstrator controls the drive motors to drive the cutting head to adjust different postures, and calibrate and set the distance between the metal induction chip corresponding to the feedback voltage of the corresponding postures and the cutting panel cut in a multi-point manner. The control system has higher compatibility and stability.
Description
technical field [0001] The invention relates to the technical field of 3D laser cutting, in particular to a control system based on three-dimensional five-axis 3D laser cutting. Background technique [0002] Laser processing uses the energy of light to reach a high energy density at the focal point after being focused by a lens, and is processed by photothermal effects. Laser processing does not require tools, has fast processing speed, and small surface deformation. It can process various materials. The beam performs various processing on the material, such as punching, cutting, scribing, welding, heat treatment, etc. [0003] The calibration method for debugging the existing laser cutting control system is relatively simple. It is mainly transferred from 2D cutting to 3D cutting. Various incompatibility problems will appear in long-term use, and its calibration method is relatively simple. Rough, linear division only by calibrating the height of two points. And because t...
