Based on the single-layer contour pattern, the comparison of the zigzag parallel hatch and the contour parallel hatch

Abstract

Laser marking refers to marking on the surface of a product with a laser mark, text, symbol, image, etc. The hatch tool of laser marking machine can be used to hatch specified 2D-compound curve graph. The direction parallel hatch and the contour parallel hatch are two basic ways of hatching. Under the single-layer contour pattern, for the zigzag parallel hatch, we established an improved area Parity Check Filling Model. For the contour parallel hatch, we established an equidistant line generation model based on the Regular Bezier curve, and used the De Casteljau algorithm to generate equidistant lines with the given hatching line spacing. By running the relevant programs, we get the total length of hatch curves and the average elapsed time of the two hatch algorithms. According to the analysis of the result, the performance of the zigzag parallel hatch algorithm is higher than that of the contour parallel hatch algorithm.
