摘要
为解决叶片工艺设计与数控编程存在的数据源不统一、工艺设计效率低以及工艺文件可视化不足等问题,通过引入MBD技术,在NX软件平台上开发出一套基于MBD的叶片CAPP-NC系统。首先建立叶片MBD设计模型;其次提出基于扩展属性邻接图的加工特征识别方法,确定加工时间最短作为加工元排序的优化目标,基于改进遗传算法对加工元进行排序;最后开发出原型系统,并验证了系统的可行性与实用性。
In order to solve the problems of inconsistent data sources,low efficiency of process design and insufficient visualization of process files in blade process design and NC programming,a set of blade CAPP-NC system based on MBD on NX software platform is developed.The MBD design model of blade is established,and the machining feature recognition method based on extended attribute adjacency graph is proposed.The shortest machining time is determined as the optimization objective of machining element sorting,and the machining elements are sorted based on improved genetic algorithm.Finally,a prototype system is developed,and the feasibility and practicability of the system are verified.
