DNC通讯系统在网络制造技术中的应用

DNC Communication System Application in Network Manufacturing Technology

DNC是Direct Numerical Control的简称,即直接数字控制,是将若干台数控设备直接连接在一台计算机上,由中央计算机负责数控程序的管理和传送.目前DNC系统不仅包括NC程序,而且包括执行特定生产任务所需的制造数据,如刀具数据、作业计划、机床配置信息等,部分DNC系统还具有机床状态采集和远程控制等功能.

DNC is referred to the Direct Numerical Control（also direct digital control）. It means a number of numerical control equipment directly connected to a computer, and the central computer in charge of the NC program＇ s management and transfer. At present, DNC system includes not only the NC program, but also the manufacturing data of the specific tasks required for the production, such as cutting tools data, scheduling, configuration information of machine tools, and so on, and part of the DNC system also has the functions of machine tool state acquisition and re-mote control.
