介绍数控技术的当前发展趋势，提出虚拟数控系统的概念，描述其应具备的功能，认为虚拟数控系统应有完善的培训功能、多媒体的仿真功能、全面的设计功能以及综合的评价功能，其体系结构应由虚拟培训学习平台、虚拟设计开发平台、虚拟操作运行平台以及虚拟监控评估平台４ 部分构成。讨论相应的一些支撑技术即虚拟设计系统、虚拟仪器系统和虚拟运动控制器。
This paper introduces the current development trend of numerical control technology, puts forward the concept of virtual numerical control system and describes the functions it should have. It believes that virtual numerical control system should have perfect training function, multimedia simulation function, comprehensive design function and comprehensive evaluation function. The structure should be composed of 4 parts: virtual training and learning platform, virtual design and development platform, virtual operation and operation platform and virtual monitoring and evaluation platform. Discuss the corresponding support technologies that virtual design system, virtual instrument system and virtual motion controller.
