摘要
文章通过对2.5轴和3轴铣削加工过程及信息需求分析,详细论述了基于NC特征单元的数控加工过程。并在此基础上构造了以NC特征单元为核心的NC领域产品信息模型。该产品模型不仅适合于CAD/CAPP/NCP集成,而且能够满足NCP/CNC的信息集成需求。
This paper provides a new idea about NC feature unit.By analyzing the information requirement and NC_ma-chining process for2.5D and3D surface,the function and definition of NC feature unit are described in detail.Based on NC feature unit,NC domain product model is defined.This model can be used to both CAD/CAPP/NCP integration and NCP/CNC integration.
