Product model was categorized into product model for unit product model for cax , virtual product model for digital prototyping and virtual product model for life cycle . the product model technology was summarized 将产品模型分为面向cax技术的单元产品模型、面向数字原型的虚拟产品模型和面向全生命周期虚拟产品模型,并对产品模型技术进行综述。
On one hand , c3m seeks a kind of integration environment of all items of cax technology and the inner data logic among them , on the other it studies the object - oriented mis development methodology C ~ 3m一方面寻求一种各cax等单项计算机辅助技术的集成环境及其之间的数据逻辑,另一方面,则对基于面向对象技术的mis系统软件设计方法进行了尝试与研究。
Step has been applied into cad / cam systems , so step - nc makes information bidirectional between cnc and other cax systems ; the richer information in the program files raises the level of intelligent functions of cnc 因为step标准已经在cad / cam阶段实现,所以step - nc使cnc与其它cax系统之间实现了信息的双向流通,丰富了数控程序的信息含量,提高了cnc的智能化水平。
We call it the icax mode of intelligent application software generation . the key of this mode is to generate knowledge base , which is the source of intelligence of icax software , independently and parallel to intelligent software development 本文以作者主持过的三个项目为例,提出了cax基本框架x知识库icax的智能化应用软件开发模式,其关键在于x知识库的自动生成。
Therefor , it is very necessary to research the pdm - enabled distributed virtual design platform ; and it is very essential to integrate all kinds of cax application system and explore a high efficiency , fast design method in pdm platform 因此,研究基于pdm的分布式虚拟设计平台,在pdm平台上,集成各种cax应用系统,并在此平台上探索一种高效、快捷的设计方法十分必要。
