摘　　要：在现行的国家标准中,采用图例及文字说明的形式来定义公差,适合于手工设计环境,不适合于计算机的表达、处理以及在各阶段的数据传递。建立平面要素方向公差数学模型,以自由度变动作为平面要素方向公差模型变量,用数学的方式来描述和解释公差信息中成员的含义,表示平面要素公差域及实际平面要素的变动情况,在计算机中合理且有效地表示公差信息,有利于CAD/CAM有效集成、自动检测与评定技术的发展。In current national standard, it is suitable for the manual design environment to define the tolerance in the form of figures and text,but not suitable to be expressed, processed and data transfer in various stages with computers. So the mathematical model of orientation toler-ance for plane feature is established, taking DOF variation as its variable, using mathematical methods to describe and explain members of toler-ance information, to express its tolerance domain and its actual variation, and to express the tolerance information in compute r reasonably and sufficiently. As to CAD/CAM, it is beneficial to the technology development of its sufficient integration, automated test and evaluation.
