Research And Application Of Wood Engraving Technology Based On VRML

As the country's economic prosperity, the people's demand for art is also more and more strong, carving technology is also becoming more and more market prospects. The traditional manual engraving is more and more difficult to meet the needs of modern industrial production in the production efficiency and precision. Therefore, in recent years mechanical profiling carving processing technology is carved into the industry to the enormous role, especially patterns and text carving ability accelerates the pace of development of mold industry, for the carving art of this technology is widely used in the field of industrial laid a solid foundation. However, the mechanical profiling carving processing object is still very limited. Study on mechanical profiling carving has strong practical significance.Virtual reality technology has been developed rapidly in recent years, with its ability to reproduce the three-dimensional features of objects. In this paper, the Chinese character as the main object of calligraphy, the VRML virtual reality technology applied to the CNC engraving technology, the realization of the CNC engraving machine system, the engraving machine system can be based on 2D images of CNC engraving.According to the characteristic of the edge contour of the digital image processing, the method of image edge detection is proposed, and the specific detection algorithm is presented. Takes into account both the can keep consistent well with the original features, but also is convenient for subsequent processing, proposed in the corner detection and value point set based, double circular arc fitting of image vectorization method separately. In this paper, the method of cutting edge and cutting edge is used to make the tool path generation. And according to regional processing object, characteristics of tapered edges and corners, the machining process for the rough machining and complete in two steps, in order to meet the requirements of machining efficiency and machining precision and complete machining process path automatic judgment. Based on the above ideas, the tool path generation method is presented. In addition, the tool path generation model is established, and the coding rule is designed. The simulation results show that the tool path has a certain practical value. At last, the paper introduces the VRML technology in the VC++6.0 open environment, realizes the simulation of the engraving process, and completes the construction of the whole software system. After inputting Chinese character image information, the system can complete the functions of image vector, tool path generation and motion simulation.
