The basic conception of digital assembly process is presented.
提出了数字装配工艺的基本概念；
The traditional computer aided process planning systems are two-dimensional, and now there aren 't commercial three-dimensional digital assembly process planning systems.
传统的计算机辅助工艺规划系统都是二维的，目前国内外尚无成熟的三维数字化装配工艺系统出现。
So it is very important in theory and practice that the basic assembly process of digital product and key matching elements are researched.
因此进行数字化产品基本装配过程及关键匹配要素的研究就具有理论意义和实用价值。
