工艺规划数据模型的构造

本文阐明计算机辅助工艺规划中一种新的数据模型，构造和表达一般性工艺规划进程，工艺规划数据模型包括产品模型和方法模型两个部分。产品模型表达产品在机械加工过程中各个状态；方法模型描述对产品进行加工的工艺方法和操作顺序。

DATA MODELING FOR PROCESS PLANNING

This paper describes a new data model of CAPP(Computer-Aided Process Planning). It consists of two components: product model and method model.Product model expresses all process states of product. Method model is about process methods and process constructs. In CAPP data model, product information drivers method model, and method modifies product data. And so, the relationship between product and process method is established. The data model, which can express general product's process planning, is effective for representation, exchange and intergation of product data in CAD/CAPP/CAM system.
