数控(NC)系统是数控机床的核心,是机械制造业实现集成化、全自动化、智能化的关键设备之一。只有NC系统发展了,才能发展更先进的柔性制造单元(FMC)、柔性制造系统(FMS)以及计算机集成制造系统(CIMS)。我国的NC系统,经过“六五”期间的技术引进、散件组装和“七五”期间的消化、吸收、国产化历程,到“八五”期间,已能自行开发具有我国自己版权的高中档产品;NC机床国产化专项规划中共安排技改项目64个
NC (NC) system is the core of CNC machine tools, machinery manufacturing industry to achieve integration, automation, intelligent one of the key equipment. Only with the development of NC systems can more advanced FMCs, FMSs and CIMS be developed. China’s NC system has been able to develop by itself during the “65” period of technology introduction, assembly of spare parts and “digestion, absorption and localization during the” 75 "period China has its own copyrights of high school products; NC machine localization of the special planning of the CPC arranged 64 technical transformation projects
