From a different perspective, equipment fault diagnosis theory and method are many, the fault diagnosis expert system method is one of the most significant achievements in fault diagnosis field in recent years, its content including diagnosis knowledge expression, diagnosis reasoning method, uncertainty reasoning and diagnosis knowledge acquisition etc. 　　[关键词]数控机床 故障树分析 [key words] nc machine tool fault tree analysis 　　 　　一、数控机床故障的诊断研究意义所在 A, numerical control machine tool fault diagnosis research is all about 　　故障诊断始于机械设备故障诊断,主要指制造设备和制造过程的状态监测与故障诊断。制造设备主要指加工机床、夹具、量具和刀具;制造过程指制造工艺过程、工艺参数。机械设备运行时的状态监测与故障诊断包含两方面内容:一是对设备的运行状态进行监测;二是在发现异常情况后对设备的故障进行分析、诊断。 Fault diagnosis begins with mechanical equipment fault diagnosis, mainly refers to the manufacturing equipment and manufacturing process of condition monitoring and fault diagnosis. Manufacturing equipment is mainly refers to the processing machine tools, fixtures, measuring and cutting tools; Manufacturing process refers to the manufacturing process and process parameters. Condition monitoring and fault diagnosis of mechanical equipment runtime content contains two aspects: one is to the equipment running status monitoring; 2 it is after anomalies have been found to equipment fault analysis and diagnosis. 　　设备故障诊断是随设备管理和设备维修开展起来的。欧洲各国在欧洲维修团体联盟(FENMS)推动下,主要以英国倡导的设备综合工程学为指导;美国以后勤学为指导;日本吸收二者特点,提出了全员生产维修(TPM)的观点。 Equipment fault diagnosis is developed along with the equipment management and equipment maintenance. European countries in the European Union for maintenance group (FENMS), which mainly guided by the British advocate comprehensive equipment engineering; After study with the guidance in the United States; Japan absorption characteristics between them, and put forward the total productive maintenance (TPM) point of view. 　　美国自1961年开始执行阿波罗方案后,出现一系列因设备故障造成的事故,导致1967年在美国宇航局(NASA)倡导下,由美国海军研究室(ONR)主持成立了美国机械故障预防小组(MFPG),并积极从事技术诊断的开发。美国诊断技术在航空、航天、军事、核能等尖端部门仍处于世界领先地位。 Since the Apollo programme started in 1961 in the United States, appear a series of accidents caused by equipment failure, lead to the NASA (NASA) in 1967, under the sponsorship by the U.S. naval research (ONR) host formed the mechanical failure prevention group (MFPG), and actively engaged in the development of diagnosis technology. The diagnosis technology in aviation, aerospace, military, nuclear and other cutting-edge department is still in the world leading position. 　　英国在上世纪60-70年代,以机器保健和状态监测协会(MHMG&CMA)为最先开始研究故障诊断技术,在摩擦磨损、汽车和飞机发电机监测和诊断方面具领先地位。 UK in the last century 60 s - 70 - s, in order to machine care and state monitoring association (MHMG&CMA) as the first began to study fault diagnosis technology, the friction and wear, cars and aircraft generator monitoring and diagnosis has the leading position. 　　日本的新日铁自1971年开发诊断技术,1976年到达实用化。日本诊断技术在钢铁、化工和铁路等部门处领先地位。 Japan's Nippon steel since 1971, when the development of diagnostic techniques, to achieve practical application in 1976. Japanese diagnostic technique in iron and steel industry, chemical industry and railway departments in the lead. 　　我国在故障诊断技术方面起步较晚,1979年才初步接触设备诊断技术,近年来得到迅速开展。目前国内对装备的故障诊断技术,尤其是板级故障诊断技术的研究有了较大的进展。经过二十多年的研究与开展,我国的故障诊断技术己广泛应用于军工、化工、工业制造等领域,如数控机床、汽车、发电、船舶、飞机、卫星、核反响堆等。 In fault diagnosis technology started late in our country, the preliminary contact with equipment diagnosis technology, in 1979 got rapid development in recent years. At present domestic to equipment fault diagnosis technology, especially the board level fault diagnosis technology research has made big progress. After 20 years of research and development, and the military-industrial complex fault diagnosis technology has wide application in our country, the chemical industry, industrial manufacturing and other fields, such as CNC machine tools, automotive, power generation, Marine, aircraft, satellites, nuclear reactors, etc. 　　二、现代故障诊断技术概述 Second, the modern fault diagnosis technology overview 　　1.故障诊断主要内容 1. Fault diagnosis and main content 　　故障诊断的实质是在诊断对象出现故障的前提下,通过来自外界或系统本身的信息输入,经过处理,判断出故障种类,定为故障部位(元部件),进而估计出故障可能时间、严重程度、故障原因等,甚至还可以提供评价、决策以及进行维修的建议。 Fault diagnosis is the essence of object in the diagnosis of malfunction of the premise, through the information input from the outside world or the system itself, through processing, judge the fault types, fault parts (components), as to estimate the possible failure time, severity, and the cause of the problem, you can even provide evaluation, decision making and maintenance advice. 　　现代故障诊断的主要内容应包括实时监测技术,
