用微电子技术改造机械设备是当前世界新技术发展的潮流,是用新兴技术改造传统工业的主攻方向,是提高产品质量、生产率及经济效益的重要手段。自从1984年9月在南京召开“全国微电子改造普通机床现场会议”以来,国内经济型数控系统已发展不少了。为了避免低水平的重复,把工作重点 The use of microelectronic technology to transform machinery and equipment is the trend of the development of new technologies in the world at present. It is the key direction to transform traditional industries with emerging technologies and is an important means to improve product quality, productivity and economic benefits. Since September 1984 held in Nanjing, “National Micro-electronics Machine Tool Conference on-site reform,” the domestic economy CNC system has been developed a lot. In order to avoid the low level of repetition, put the focus of work
