So it is necessary to carry on technological transformation to the old-fashioned regular motor control system and replace normal regulations by programmable preface controller of after electric appliances with attain grinding machine of automation control. This text introduced comes with the programmable controller to the surface grinding machine control system to make the modernized transformation, narrated the old style formation surface grinding machines principle of work briefly and carries on the transformation design with PLC the method and the design procedure, and gives PLC the programming procedure trapezoidal chart . After the reformation of grinding machine work safety credibility, he systems operation situation is good, the grinding precision is higher; Using the PLC control grinder movement, realized the grinder to start, the stop, the breakdown to stop, the emergency stop function, might cut grinders control mode nimbly according to the movement request; Provides the overload, the underloading, breaks and the voltage is not balanced protects; The scene demonstration running status, realizes the intellectualized monitoring. Because and attracts the work piece the different nimble adjustment magnet chuck electric current, and demonstration value size. Thus has realized the grinder movement automation. The PLC controls characteristic causes the original machine tool control big simplification, and services conveniently, easy to inspect. Saves the massive relay element, causes engine beds working efficiency to be higher. This technology may also promote applies in other auxiliary engine equipment or in other domain automated control transformation.Keywords Programmable logic controller Flat surface grinding machine Reformation 1 目 錄1緒論12磨床的概述32.1磨床的介紹32.2世界平面磨床發(fā)展趨勢33可編程控制器的概況53.1PLC的產生和特點及其發(fā)展動向53.1.1PLC的產生53.1.2PLC的定義53.1.3PLC的特點63.1.4PLC的發(fā)展趨勢73.2PLC的系統(tǒng)結構和基本工作原理83.2.1PLC的系統(tǒng)結構83.2.2PLC的系統(tǒng)結構和基本工作原理93.2.3PLC的主要功能103.2.4PLC的應用設計步驟113.3PLC的選型原則124系統(tǒng)的總體設計154.1改造平面磨床的步驟154.1.1改造方案的確定154.1.2改造的技術準備154.1.3改造的實施164.1.4驗收及后期工作174.1.5用PLC改造繼電-接觸式控制系統(tǒng)的步驟184.2控制線路控制改造要求184.3原設備電器的工作原理194.3.1平面磨床主要結構和運動形式194.3.2電氣控制線路分析204.4分析控制對象，進行系統(tǒng)的硬件設計234.5系統(tǒng)的軟件設計245性能測試與分析27結論28致謝29參考文獻30附錄31中文翻譯：31外文翻譯：38徐州工程學院畢業(yè)設計（論文） 1
