在最终产品生产者的数据联系中，如果将配件供应者也包括在内，则要求进行几何数据交换。作者利用从计算机内部接收到的来自用户的成品几何模型作为基础，进一步在计算机内进行三维锻件设计。他们研究了不同的数据模型，开发出了设计方案，通过基础零件对方案进行检验，并且为设计者制订了设计准则和实施细则。 In the data connection of the final product producer, geometrical data exchange is required if accessory suppliers are also included. The author uses the finished geometry from the user received from inside the computer as a basis for further three-dimensional forging design in the computer. They studied different data models, developed a design solution, verified the plan through the base parts, and developed design guidelines and implementation rules for the designer.
