摘要
针对基于特征的CAPP/CAM系统不能完全自动工艺决策以及交互工艺决策效率低等问题,本文提出了基于局部特征的飞机结构件快速交互工艺决策方法。该方法在局部特征识别结果的基础上,通过调用典型特征工艺知识库,生成局部特征工艺信息模型,并采用交互手段对工艺模型进行编辑修改,完成工艺决策。实例应用表明:该方法扩大了基于特征的自动工艺决策系统的应用范围,提高了工艺决策和数控编程效率。
A part feature-based process planning method is proposed to address the problem concerning the incomplete automatic process planning of the feature-based CAPP / CAM system and the low efficiency of the interactive process planning. In this method, part feature is recognized first. Then typical feature-based process knowledge database is called to generate part feature process information model. Ultimately, the process information model can be edited by processer to complete process planning. This method expands the scope of application of the automatic process planning system based on feature, and improves the efficiency of process planning and NC programming.
