Five-axis linkage machining method for laser engraving machine

Abstract

The invention provides a five-axis linkage machining method for a laser engraving machine. The 5-axis linkage machining method comprises the following steps: (I) programming: (1) modeling; (2) creating three image layers by using Rhinoceros software; (3) performing image processing; (4) mapping images processed in the step (3) to a mapping mesh by the Rhinoceros software; (5) performing error preview; (8) performing calculation; (II) performing simulation; (III) machining: after the simulation is finished, performing machining by the laser engraving machine through the five-axis linkage of a coordinate axis X, a coordinate axis Y, a coordinate axis Z, the rotation axis A of a laser head and the axis B of the turning table of a machine board. According to the five-axis linkage machining method for the laser engraving machine, provided by the invention, the condition that a curve can be possibly stretched and distort in a process that the mesh is flattened by Uvlayout software is changed; mapping is integrated and full, and is free of distortion and defects; the step and time for flattening the mesh are saved, and the work efficiency is increased.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a five-axis linkage processing method for a laser engraving machine. Background technique [0002] In the field of mechanical processing, the laser identifies the processing depth through the grayscale image. For the processing of the curved surface, the corresponding grayscale image needs to be attached to the surface of the curved surface, so that the laser can process perpendicular to the curved surface or at the required angle. [0003] A certain type of curved surface, such as a sphere and a conical surface, is not a uniformly distributed grid after it is made into a grid, but shrinks toward the center. During the flattening process of this type of grid using Uvlayout software, the center position is due to the grid If the grid density is too high, it will be distorted and deformed, so that it will be distorted according to the grid distortion direction after mapping.

[0003] A certain type of curved surface, such as a sphere and a conical surface, is not a uniformly distributed grid after it is made into a grid, but shrinks toward the center. During the flattening process of this type of grid using Uvlayout software, the center position is due to the grid If the grid density is too high, it will be distorted and deformed, so that it will be distorted according to the grid distortion direction after mapping. The carved texture obviously does not meet the requirements. If other processing methods such as upper and lower layers are used instead, the workload will increase. times, error prone and seams, still has obvious flaws
