随着科学技术和生产的不断发展,社会对各种产品的质量和生产效率提出了越来越高的要求,特别是对于多品种、小批量、形状复杂、精度要求高的零件的加工,采用专门化程度很高的自动机床和自动生产线就显得很不合适。一种灵活、通用、高精度、高效率的“柔性”自动化生产技术即数控技术在这种情况下应运而生。数字控制(NC)简称为数控,它是用数字化信号对设备运行及其加工过程进行控制的一种自动化技术。NC 装置由各种逻辑元件、记忆元件组成随机逻辑电路,是固定接线的硬件
With the continuous development of science and technology and production, the society has put forward higher and higher requirements on the quality and production efficiency of various products, especially for the processing of parts with many varieties, small batches, complicated shapes and high requirements of precision High degree of specialization automatic machine and automatic production line is very inappropriate. A flexible, universal, high-precision, high-efficiency “flexible” automated production technology that is numerical control technology in this case came into being. Digital Control (NC), or simply NC, is an automation technology that uses digital signals to control the operation of a device and its process. NC device by a variety of logic components, memory components composed of random logic circuit is fixed wiring hardware
