基于Edgecam的数控编程加工工艺表自动生成技术研究∗

摘要

针对数控编程加工工艺表的智能生成问题，研究基于Edgecam软件的自动化生成方法。首先，在基于Edgecam的基础上提出了工艺表智能生成的系统设计方法，而后，论述了工艺表特征数据提取和Excel 工艺表格生成等关键技术，以Excel为后台，利用VB. NET并结合PCI和PDI等二次开发语言编写了程序，最后以典型零件的数控编程的实例证明了方法的有效性，实现了工艺表格的智能化和快速化生成，为其它产品数控编程的工艺表生成提供了借鉴。%In order to solve the intelligently generating of processes form in CNC programming, the method of automatic generating based on Edgecam software was introduced. Firstly, the ideas for intelligent genera-ting in Edgecam is proposed, then, the key technology of feature extraction of processes form and writing method by Excel were studied, the program was written in VB. NET, PCI, PDI and other secondary devel-opment languages in Edgecam, finally, the case study used in a typical part with the proposed method, which provides reference for the processes form generating intelligently and rapidly in other product.
