面向大批量定制的NC加工智能化设计

为了更好的支持面向大批量定制技术的NC程序设计,在专家工艺知识和前期零件加工工艺路线的基础上,使用Visual Lisp语言编制了NC智能化设计系统。采用事物特性表技术,从产品数据管理（PDM）系统的主图中派生出CAD工程图,并通过调用接口进入系统界面。重点分析了NC智能设计的模块化思想,以及运用数据数组使系统智能识别加工零件的基本特征,并通过切削运行轨迹的动态仿真过程得到了NC程序代码,以支持产品大批量定制的NC加工智能化设计。最后,应用T6436汽轮机转子通流段实例进行了原理验证。研究结果表明：NC加工智能化设计为大批量定制技术奠定了基础。

Intelligentized design of NC process for mass customization

In order to better support design for mass customization,on the basis of the summarizing the expert-craft knowledge and the former craft line of processed part,the intelligentized design system of numerical control（NC） was programmed through Visual Lisp language.On the basis of the layouts of article characteristics,the CAD engineering draft was derived from the main draft in product data management（PDM） system.Then,it was put the system interface through transferring interface.Especially,the module idea of the NC intelligentized design was analyzed.And the basis characteristics of the processed part were distinguished by the system through applying the data group,the NC code was obtained through the dynamic emulation of the operating cutting track.The T6436 rotor circulating part was exampled to validate the principle.The results indicate that the intelligentized design of NC process lays the foundation for the MC technology.
