摘要
基于 PC的开放式数控系统将逐步取代传统的专用数控系统 ,在这一前提下 ,提出衍生式计算机数控系统。它是将原有系统作为一功能部件 ,对其进行衍生式设计 ,使其具有开放系统的功能和特征。文章给出了衍生式计算机数控系统的基本原理和体系结构以及软件和硬件实现方法 ,介绍了其在椭圆活塞
A new kind of CNC system,ECNC ( extracted CNC system) is presented in this paper.ECNC can be considered as the bridge between the traditional PACNC ( proprietary architecture CNC) and OACNC ( open architecture CNC system) during shifting PACNCtowards OACNC.It uses old OACNC as one of the system components and has the functions and features of open architecture system.Two kind of ECNC systems, functional extracted CNC( FECNC) and PC-based open extracted CNC( OECNC) are included.The basic principle and system scheme,the implementation of hardware and software of the new system are given in the paper.An example which uses ECNC to elliptical piston CNC turning machine is also presented to show the usefulness and effectiveness of the ECNC system.
