In the CNC engraving processing, the mold industry and the advertising industry have requirements for CNC engraving processing of Chinese characters. Generally, there are two methods to generate Chinese character NC engraving codes. One is to use Windows' TrueType font feature to obtain its outline for CNC machining. This processing method corresponds to each stroke of Chinese characters, and the cutter will go twice, so the processing effect on small characters or fine fonts is not good. The second is to directly generate the NC code by using the single-line font added in Windows. Since the single-line font cannot be converted into other fonts (such as 楷, 仿宋, etc.), it is often impossible to meet certain special requirements. Applying the method of mathematical morphology, the Chinese characters are refined, the skeleton is taken out, and a single line word is formed. Then the software automatically generates the NC code for engraving, which is suitable for Chinese characters of any font, so that each tool has only a few strokes for Chinese characters. Users are designing the same sheet of paper. In addition, they can also communicate in real time through the message bar on the right. It should be pointed out that although the models displayed between the same group of users are all consistent, only the project creator (project leader) or some specific users have the right to save the project to the area corresponding to the project in the database (project database). However, other users can only save the model to the area (user database) opened by the database for itself, and have no right to update the project database. The 21st century is an era of knowledge economy. Whether enterprises can make good use of their own and external intellectual resources, whether they can achieve rapid innovation of knowledge, is of great significance to the development of enterprises. The knowledge management collaborative modeling system based on B/S mode proposed in this paper is beneficial to the knowledge model to negotiate and model the cross-regional negotiation within the enterprise and to go once to achieve good CNC machining for small Chinese characters. The outline of the Chinese character, the skeleton and the outline of the refinement image are the closed curve or closed curve set surrounding the target artifact. Under Windows, Chinese characters are TrueType fonts, which use the control points of the record words to save the outline of the words, and then fill the outlines to form Chinese characters. Therefore, a special API function GetGlyphOutline function of Windows can be used to obtain the coordinate information of the control point, and a B-spline curve is obtained. The points on the contours of a series of spline curves are obtained in a small interval, and connected by a polyline. , get processed vector data. In addition, the coordinate value of the contour points can be obtained by the contouring algorithm of the Chinese character image (such as the seed algorithm), and the dynamic collaborative modeling between the enterprises is adopted. The management of modern enterprises adapts to globalization, informationization, and networkization. Development has a certain help.
