世界上在30至50年代,由于汽车工业的迅速发展,设计制造了大量的高效率、自动化单机和各种自动生产线。为这些机床配备了各种各样的自动测量仪,促进了生产自动化的大大发展。到了七十年代,由于电子技术和计算技术的发展,才使数控(NC)、适控(DC)机床得到大力推广应用,从而使群控(DNC),柔性制造系统(FMS)和计算机辅助制造(CAM)能向生产自动化和无人化更高水平方向发展。普通型自动或半自动外圆磨床,一般只能磨削一个或几个轴台直径的工件,其砂轮相对于各轴台的直径之位置一般由手工操作。而数
The world in the 30s and 50s, due to the rapid development of the automotive industry, design and manufacture a large number of high efficiency, automated stand-alone and a variety of automated production lines. Equipped with a wide range of automatic gauges for these machines, the automation of production has been greatly accelerated. By the 1970s, due to the development of electronic technology and computing technology, NC and DC machine tools were greatly promoted and applied, so that DNC, FMS, and computer-aided manufacturing (CAM) to the production automation and unmanned higher level development. Ordinary automatic or semi-automatic cylindrical grinder, the general grinding only one or a few shaft diameter workpiece, the wheel relative to the diameter of the position of the pillow block generally by hand. And the number
