基于模型定义技术使三维模型成为产品设计生产过程中的唯一依据,这一应用必然改变传统的生产模式。文章在基于模型定义技术的背景下,提出了飞机数字化装配工艺设计及应用模式,在该模式下,通过工艺方案设计和详细工艺设计,完成了三维装配指令的构建,从而为装配现场可视化提供了依据。 Based on the model definition technology, the 3D model becomes the sole basis for the product design and production process. This application is bound to change the traditional production mode. Based on the model definition technology, this paper presents the design and application mode of aircraft digital assembly process. Under this model, through the process design and detailed process design, the three-dimensional assembly instruction is completed, which provides the visualization of the assembly site in accordance with.
