摘　　要：通过提取 True Type字体以直线段及二次 Bezier样条曲线描述的字符轮廓信息 ,可以实现对字符的任意放大、缩小、旋转和变形等特殊效果 ,曲线轮廓可以进行填充。经逼近、节点划分处理后 ,由数控机床进行插补加工。It has become more and more popular for Chinese characters to be used in the products of manufacturing industry.Special effect of free font zoom.out,rotating adn reshaping are available by taking the straight line as well as the font contour information depicted by quadratic Bezier kind curve from the TrueType font.Furthermore,the contour curve can be interpolated by numerical control tools after being treated by approaching and node dividing.
