三、机床数字控制系统随着数控机床的发展和普及,要求机床数控系统的水平不断提高和改进,控制装置的结构也发生了根本的变革。这里着重介绍有关数控系统的概念、分类、插补原理等内容。1.数控系统的一般概念传统型的数控系统是硬件数控系统,也称NC数控系统。整个系统的输入、插补计算、控制、输出等部分均是由硬件逻辑线路所组成,所以硬件结构较复杂,数控功能也相应受到很大的限制。这种系统对修改、调整、维修均带来很多的困难。
Third, the machine numerical control system With the development and popularization of numerical control machine tools, CNC machine tools to improve the level of continuous improvement and improvement, the structure of the control device has undergone fundamental changes. Here focuses on the concept of CNC system, classification, interpolation principle and so on. 1. The general concept of CNC system Traditional CNC system is a hardware CNC system, also known as NC CNC system. The entire system of input, interpolation calculation, control, output and other parts are composed of hardware logic circuits, so the hardware structure is more complex, numerical control functions are also subject to great limitations. Such a system brings many difficulties to modification, adjustment and maintenance.
