Laser cutting method and device

Abstract

The invention discloses a laser cutting method and device. The method comprises the steps that all material attributes corresponding to all to-be-cut parts on a to-be-cut workpiece are obtained; according to the material attributes corresponding to the to-be-cut parts, pulse width lasers matched with the material attributes are obtained; and all the pulse width lasers are adopted, and all the to-be-cut parts of the to-be-cut workpiece are cut. Different materials on the to-be-cut workpiece are cut through lasers with different pulse widths according to different materials, so that it is guaranteed that the pulse widths of all the lasers are matched with the attributes of all the materials, the heat effect generated by the lasers on the to-be-cut portions where the materials are located is reduced, and the lower the degree of the heat effect is, the higher the cutting efficiency is. The carbonization degree generated by the cutting part can be reduced, the carbonization degree is smaller, the quality of the cut workpiece is better, and the use effect of the cut workpiece can be guaranteed.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a laser cutting method and device. Background technique [0002] Laser cutting is a technique of cutting material using a laser, often used in industrial manufacturing applications. Laser cutting generally works by directing high-power laser output through optics. The laser optical system and numerical control system are used to guide the generated laser beam, and through the guidance, the laser beam is focused on the material, and then the material is melted, burned, evaporated or blown away by the gas jet to complete the cutting of the material. [0003] The workpiece to be cut contains materials with different properties, some materials are metal, and some materials are non-metallic. The existing laser cutting method uses laser with the same pulse width to cut each material of the workpiece to be cut, resulting in carbonization of some materials. , thereby reducing the use ef...
