机床制造业是一个国家的基本工业,是机器大工业生产的技术基础。数控机床是机电一体化的典型产品。机床数控化是机床行业技术进步的必由之路,在工业国家,数控机床占其机床总数的30～40%,技术轨迹日趋高、精、尖,目标方向仍是数控机床→柔性制造单元→柔性制造系统→计算机集成制造系统及至无人化车间和自动化工厂。主流仍是数控机床,特别是以实现一次装夹后的全部加工是当前机床在加工工艺上的发展趋势。而作为数控机床核心的数控系统技术发展十分迅速,各国以期抢占21世纪高科技制高点,足以引起我们关注和重视。
Machine tool manufacturing industry is a country’s basic industry, is the machine large industrial production technology base. CNC machine tools are a typical mechatronic product. In the industrialized countries, CNC machine tools occupy 30-40% of the total number of machine tools, and the technical track is getting higher and higher. The direction of precision and sharpness is still the target of numerical control machine tools → flexible manufacturing unit → flexible manufacturing system → Computer Integrated Manufacturing Systems to unmanned workshops and automated factories. The mainstream is still CNC machine tools, in particular, to achieve a clamping all the processing is the current machine tool in the processing technology trends. The numerical control system as the core of CNC machine tools developed rapidly. All countries are trying to seize the high ground in the 21st century, which is enough to arouse our concern and attention.
