摘　　要：提出了识别轴类零件外轮廓的逆时钟最小夹角法,讨论了五种特殊角度计算及多对象相切情况的处理方法,确定了轮廓点的搜索原则和中心线的处理方法。在AUTOCAD2006环境下,以ObjectArx为开发工具,实现了文中提出的原理和方法,以某典型轴类零件图为例,识别效果好。Proposes a new method based on searching minimum anti-clockwise angle to identify outline of shaft part drawings. Discusses the five specical situations of angles,and tangent multi-object at a point. Gives principles of searching and selecting drawing outline and dealing with medial axis. A program is developed under the AUTOCAD 2006 with ObjectArx, using methods and principles proposed above, which gives an effective result of identifying a typical shaft part drawing.
