一、概述数字控制是本世纪五十年代初问世的一项新技术,它所具有的一系列优点使它获得人们的重视与普遍使用。随着电子技术的飞速发展,大规模集成电路的出现和微处理机技术的高速发展,促使了数控装置的升级换代,在近十年中,使其经历了硬件数控——小型计算机数控——到现在微处理机数控的时代。新一代数控系统的控制部分,除了在硬件上由一台或多台微处理机加上少数专用的大规模集成电路片组成外,特别值得注意的
I. Overview Digital control is a new technology that came out in the early 1950s. It has a series of advantages that make it gain the attention and universal use of people. With the rapid development of electronic technology, the emergence of large-scale integrated circuits and the rapid development of microprocessor technology have prompted the upgrading of numerical control devices. In the past ten years, it has undergone hardware numerical control-small computer numerical control- Now the era of microprocessor NC. The control part of the new generation of numerical control system, in addition to the hardware by one or more microprocessors plus a few special large-scale integrated circuit chip composition, particularly noteworthy
