The invention provides a path planning method and system for line laser scanning chemical milling glue scribed lines, and the method comprises the steps: 1, fixing a line laser scanner on an end effector of a five-axis numerical control machine tool, and enabling the five-axis numerical control machine tool to drive the line laser scanner to carry out five-axis linkage scanning on the chemical milling glue scribed lines; and 2, setting an included angle between the line laser emitted by the line laser scanner and the chemical milling glue scribed line in a preset range through a crossed scanning method, and scanning the chemical milling glue scribed line. Compared with the prior art, the included angle between the line laser emitted by the line laser scanner and the chemical milling glue scribed line is set in the preset range through the crossed scanning method, so that reliable data support is provided for accurately extracting the central position of the chemical milling glue scribed line; and meanwhile, a new technical route is opened up for an automatic detection technology of chemical milling glue scribed lines.
Description
technical field [0001] The invention relates to the technical field of automatic detection of the position accuracy of chemical milling rubber engraving lines, in particular to a path planning method and system for line laser scanning chemical milling rubber engraving lines. Background technique [0002] Large thin-walled parts in aircraft structures are often machined using chemical milling processes. The precision of the film engraving in the chemical milling process directly determines the accuracy of the chemical milling area. The traditional chemical milling process adopts the method of manual engraving, which has low efficiency and poor precision. Therefore, the aviation industry gradually adopts the CNC five-axis laser engraving machine to replace the traditional engraving method, but at present there is no mature chemical milling rubber engraving line detection technology suitable for the engraving process. During the survey, the craftsmen tested the accuracy of th...
