本文从技术上分析了国内外数控系统的发展现状,论述了专用体系结构、非标准总线模块化结构、PC平台体系结构三种形式数控系统的特点.指出了基于PC平台开发数控系统是适合我国国情的有效途径.阐明了多CPU、前后台、多任务控制方案,和CAD、CAM、CNC一体化的思想,有效地解决了编程与控制脱节及编程机时占用与机床控制之间的矛盾.该控制方案已在超人CNC系统中得到实现,并取得较好的运行效果.本文从技术上分析了国内外数控系统的发展现状,论述了专用体系结构、非标准总线模块化结构PC平台体系结构三种形式数控系统的特点.指出了基于PC平台开发数控系统是适合我国国情的有效途径.阐明了多CPU、前后台、多任务控制方案,和CAD、CAM、CNC一体化的思想,有效地解决了编程与控制脱节及编程机时占用与机床控制之间的矛盾.该控制方案已在超人CNC系统中得到实现、并取得较好的运行效果.
This paper analyzes the status quo of CNC system at home and abroad technically, and discusses the characteristics of three forms of CNC system, including special architecture, non-standard bus modular structure and PC platform architecture.It is pointed out that developing NC system based on PC platform is suitable for our country The effective way of the national conditions.Emphasized the idea of multi-CPU, front and backstage, multi-tasking control programs, and CAD, CAM, CNC integration, effectively solve the conflict between programming and control disconnect and programming machine occupancy and machine control. The control scheme has been realized in the Superman CNC system, and achieved good operating results.This paper analyzes the status quo of CNC system at home and abroad technically, discusses the architecture of the special-purpose architecture, non-standard bus modular architecture PC platform It is pointed out that the development of CNC system based on PC platform is an effective way to adapt to the national conditions of our country.It also expounds the idea of multi-CPU, front and back stage, multi-task control scheme, integration with CAD, CAM and CNC, Solve the programming and control out of line with the programming machine and machine control and control of the contradiction between the control program has been in the Superman CNC system To achieve, and achieved better operating results.
