摘要
介绍了三种常用的ＣＡＤ／ＣＡＭ系统中ＣＡＤ模型数据交换标准格式和发展状况，分析了各种格式的特点和进行系统之间数据转换常出现的缺陷。提出了在ＣＡＤ模型数据转换中应遵循的建模原则、转换质量的保证措施以及应遵守的规章制度。
Abstract Introduce three standard formats of CAD model data exchange which are common in use in CAD/CAM system and their developping state. Analyse features of each format and defects occurred while data exchange between systems.Present die-setting priniciple during data exchange,measures of quality guarantee for exchange as well as rules and regulations that should be observed.In the last of the paper, developping trend of the data exchange is discussed.
