摘要
为解决飞机结构件数控加工工艺决策效率低下的问题,提出基于MBD的飞机结构件工艺设计方法。该方法采用MBD技术,在CATIA环境下对飞机结构件进行标注,通过特征识别技术提取相关加工特征的几何信息和非几何信息并进行刀轨规划,经后置处理导出NC程序并完成加工。
In order to improve the efficiency of the NC machining process decision of Aircraft structural parts, a process design is proposed based on MBD in this paper. The aircraft structural parts are marked with the CATIA by MBD. Geometry information and non-geometry information of the concerned machining features employing feature recognition are extracted before design the tool path. Finally, NC program are exported by post-processing and complete machining.
