Research on CNC wire cutting programming system. Due to the limitation of the wire cutting process, the processing object of the CNC wire-cut image vectorization module is mainly block diagram. The vectorization technique is used to process the vectorization of the maple leaf to be cut before and after the vectorization. After the original image is scanned by the scanner, it is stored in BMP format, binarized, denoised, and then edge-identified by the Sobel edge extraction algorithm. The superiority of the Sobel algorithm in the processing of block diagram structure: after the image is vectorized, the edges are clear, the line segments are continuous, and the contours have no redundant lines. This illustrates the practical significance of this image vectorization technology in CNC wire cutting.
Image vectorization system pays attention to the selection of processing algorithms in the process of image preprocessing and vectorization, and the final vector graphics are saved in binary DXF file, which makes the image vectorization effect better, the graphics read speed block, and enhances the whole CNC line. The intelligent level of the cutting automatic programming system makes the programming method more perfect. Image vectorization technology can be used not only in CNC wire cutting automatic programming system, but also in the fields of CNC laser engraving processing, topographic map intelligent input, automatic drawing of engineering drawings and other pattern recognition. The key to image vectorization technology is the selection of preprocessing algorithms. In order to improve the accuracy of image recognition and develop the pattern recognition technology to a completely intelligent recognition direction, it is still necessary to study a stronger and newer image processing algorithm.
