并行设计环境下齿轮传动CAPP建模方法的研究

齿轮零件是典型的机械零件，针对齿轮传动的特点，提出并行设计环境下齿轮传动零件的CAPP系统的技术原理与实现方法。建立了参数化特征信息模型，提出关联特征约束推理和特征分组的方法。采用基于特征模型的工艺设计方法，建立了工艺知识库，提出了基于规则的工艺决策方法，使特征模型能较好地应用于齿轮传动CAD／CAPP设计。

Study on CAPP of Gear Drive Based on Concurrent Design

Gear element is typical mechanical part. In accordance with gear drive characteristic, This paper put forward CAPP system technology principle and achieve method of gear drive element base on concurrent design environment,set up parameter feature information model and put forward methods for relating feature restraining reasoning and feature groups. With design method of feature mould, the technology knowledge storage and the technology strategy plan has built. It is successful for the feature model process plan method to be applied CAD/CAPP of gear drive design.
