毕业论文：数控机床故障诊断与维护.doc

摘? 要数控技术是集计算机技术、自动控制技术、测试技术和机械制造技术为一体的综合性高新技术，它将机械装备的功能、可靠性、效率、质量及自动化程度等提高到一个新的水平。数控机床故障诊断及维护在内容、手段和方法上与传统机床有很大的区别，具备数控机床故障诊断技术是正确使用数控机床的基础。数控的故障诊断是数控机床使用中重要组成部分，也是目前制约数控机床发挥作用的主要因素之一。因此，本文以系统的讲述数控机床结构及原理为基础，以阐明数控技术的基本知识和基本理论为重点，以突出数控机床及其系统的故障诊断与检测维修为关键，力图创建出集数控机床的基础知识、数控系统的的故障诊断理论和数控机床及其系统的检测维修为一体的数控机床故障诊断技术新体系。 关键词：数控技术? 故障诊断? 机床结构? 新体系。AbstractThe numerical control technology is the collection computer technology， the automatic control technology， the test technology and the machine manufacture technology is a body comprehensive high technology and new technology， it the function， the reliability， the efficiency， the quality and the automaticity which equips the machinery and so on enhance to a new level. The numerical control engine bed breakdown diagnosis and the maintenance in the content， the method and the method has the very big difference with the traditional engine bed， has the numerical control engine bed breakdown diagnosis technology is the correct use numerical control engine bed foundation. The numerical control breakdown diagnosis is in the numerical control engine bed use the important constituent， also is at present restricts one of numerical control engine bed display function primary factors. Therefore， this article take the system narration numerical control engine bed structure and the principle as a foundation， expounded the numerical control technology elementary knowledge and the elementary theory are key points， take the prominent numerical control engine bed and the system breakdown diagnosis and the examination service as the key， tries hard founds the collection numerical control engine bed the elementary knowledge， the numerical control system the breakdown diagnosis theory and the numerical control engine bed and the system examination service is a body numerical control engine bed breakdown diagnosis technology new system Key words: Numerical control technology breakdown diagnosis engine bed structure new system ? ? ? 目? 录1.数控机
