摘　　要：随着微电子技术的飞速发展,数控系统核心部件的微处理器、输入输出模块以及集成电路的可靠性越来越高的问题,所以在机床数控系统中,数控单元很少出故障,反而是其外围电气控制部分存在可靠性差、故障率较高的问题,特别是国产数控系统,这种问题尤其突出,主要表现在元器件质量、制造工艺技术以及安装使用等几个方面。着重从电气控制系统方面介绍其可靠性,并对其增长性进行分析与挖掘。With the rapid advances of microelectronics, the reliability of microprocessors, input and output modules and ICs in the core parts of a digital controlled system is very high and failures seldom occar in the digital controlled units of a machine. The major issue is the poor reliability of the peripheral electric control part, especially in the national digital controlled system, which mainly appears as the poor quality of components, processing and installation. The reliability of the electric control system was presented and its reliability growth was analyzed.
