Abstract: The generating methods of engraving graphics with set or random fractal are put forward in this paper.The engraving graphics can be controlled by the original fractal model,rules of fractal, translation and mapping.With mapping method,the engraving graphics on a plane can be translate into a trimensional graphics on an object with a complex surface.Because of the self-similarity,fine structure and iteration of the fractal,the stored information quantity for graphics can be reduced.Our methods can be used to generate the tool path for engraving and get a good artistic style.

Key words: set fractal, random fractal, engraving graphics
