提出一种面向服务的可配置可重构网络数控系统。在该系统中每台机床只配备少量的、基于嵌入式技术的数控现场执行单元,这些执行单元只具备部分数控功能,它们通过网络与一数控服务器相连,由服务器完成对多台机床的数控加工控制。系统采用组件技术,数控服务器软件由具有预定义接口的组件通过配置而构成,且可根据需要而重构。 A service oriented reconfigurable networked numerical control system is proposed. In this system, each machine tool is only equipped with a small number of CNC-based field execution units based on embedded technology. These execution units only have some numerical control functions. They are connected with a numerical control server through a network, and the server completes the numerical control processing of multiple machine tools control. The system employs component technology, which is configured by components with predefined interfaces and reconfigurable as needed.
