Embodiment Construction

[0019] refer to figure 1 , in one of the embodiments, a laser scanning method is provided, comprising the steps of:

[0020] S110: Obtain the working area to be scanned, and divide the working area by using multiple boundary lines to obtain multiple partitioned areas.

[0021] The working area to be scanned refers to the area to be scanned by laser; wherein, the boundary line is a line used to divide the working area, which may be a straight line or a curved line. Multiple boundary lines refer to two or more boundary lines. The working area is partitioned with boundary lines, thereby dividing the working area into smaller blocks.

[0022] The process flow of selective laser melting is: slice the part model of the three-dimensional workpiece to obtain the cross-section information corresponding to the contour of each layer of the three-dimensional workpiece; spread the powdery material evenly on the surface of the working platform, and the laser follows the scanning path acco...

Abstract

The invention relates to a laser scanning method, a readable storage medium and a laser scanning control device. The laser scanning method comprises the steps that a work area to be scanned is acquired, and a plurality of boundary lines are applied to partition the work area into a plurality of partition areas; a control scanner is used to sequentially scans line by line for the multiple partitionareas, wherein, a plurality of scanning lines scanning the same one of the partition areas are parallel to each other; and included angles between the scanning lines of each of the partition areas and the boundary lines of the partition areas are not equal to 90 degree, and the included angles between the scanning lines of each two adjacent partition areas are not equal to 0 degree or 180 degree.According to the laser scanning method, the readable storage medium and the laser scanning control device, the partition scanning can be realized to enable the stress generated by the laser scanningto be more dispersed, so that the problems of the buckling deformation or the cracking of the scanned workpiece are not prone to be caused, and the scanning effect is good.

Description

technical field [0001] The invention relates to the technical field of process manufacturing, in particular to a laser scanning method, a readable storage medium and a laser scanning control device. Background technique [0002] Laser scanning is often used in process manufacturing. The laser scans the processed product along the scanning path, and uses the energy of the laser beam to act on the material of the processed product to heat it, which can melt the material. For example, the selective laser melting technology of laser scanning is used to scan layer by layer by controlling the laser, and the layers are stacked to form a three-dimensional workpiece, which can manufacture metal workpieces with high process flexibility, excellent mechanical properties of the workpiece and high dimensional accuracy. [0003] The traditional laser scanning method generally uses parallel line scanning, contour equidistant line scanning, and mixed scanning of the two to scan the area that...
