【摘要】 本文以模具CAD／CAM、计算机数字控制、局域网等技术为基础，从数控系统组成结构、网络通信及CAD／CAM系统集成等方面详细研究DNC系统软硬件结构，提出一套DNC系统集成方案。 通过在模具生产现场引入以太网TCP／IP转换器，把工业现场设备通过以太网接入模具企业局域网，在此基础上能够实现数据通信、数据采集、实时控制等功能，由此提出一种新型DNC通信结构。 结合模具生产实践基础上，开发一个方便实用DNC系统，实现了局域网中主机与工业现场数控设备间双向数据传输。该系统还具有NC文件管理、数据管理、系统初始化等功能。 目前，系统经过多次实验、修正和补充，运行良好，它能够提高模具生产效率和自动化程度。本系统还可以与企业其他系统如FMS、CIMS等进行集成，具有一定柔性和扩展性。更多还原

【Abstract】 In this paper, the structure of hardware and software of the DNC system based on mould CAD/CAM, CNC and LAN (local area network) are investigated. A scheme of integrated DNC system is introduced.By using Ethernet TCP/IP converter, field devices can be connected into LAN of enterprise. So data communication, data acquisition and real-time control etc can be implemented. And a new type of communication structure of DNC system is designed.An integrated DNC system is developed. The system makes it possible for host computer to communicate with field devices. The system also has the abilities of editing NC file, processing system information and initializing system etc.The system has been tested, corrected for many times. Now, It can be run stably. It can increase the production efficiency on mould manufacturing, and the degree of automation. The system can communicate with other automatic manufacturing system, such as FMS, CIMS. So the system offers certain flexibility and expansibility.更多还原
