【摘要】 本文以中航一集团五七零四厂的XK715F数控铣床的技术改造为例，从技术和经济两个方面阐述了改造的必要性及改造方法，阐述了旧设备改造的分析方法、设备改造的要求；通过对伺服系统和数控系统的选型分析，总结出伺服系统和数控系统的选择原则，确定改造顺序，提出改造方案并加以实施。根据XK715F的现状，选用FANUCOi数控系统对其进行改造，同时对其电气系统进行改造，并根据FANUCOi数控系统内部PLC的功能，首先确定PLC的输入／输出点数，然后设计电气系统的PLC控制程序及I／O接口。运用双频激光干涉仪对数控机床的定位精度进行检测，同时进行螺距补偿和反向间隙补偿，提高了数控机床的加工精度。通过改造机床各项精度指标均符合设计要求，满足现有产品的加工精度要求。更多还原

【Abstract】 This article take China National Aviation Corp group 5,704factoriesXK715F numerical control milling machines technologicaltransformations as an example, elaborated from the technology and theeconomical two aspects the transformation necessity and the transformationmethod, elaborated the old equipment transforms the analysis method, theequipment transform request; Through to the servo system and thenumerical control system shaping analysis, summarizes the servo systemand the numerical control system selection principle, determined thetransformation order, proposed the transformation plan and performs toimplement. According to the XK715F present situation, selects theFANUCOi numerical control system to carry on the transformation to it,simultaneously carries on the transformation to its electrical system, andaccording to FANUCOi the numerical control system interior PLC function,first determines PLC the input/output points, then design electrical systemPLC control procedure and I/O connection.Carries on the examination using the double frequency laserinterferometer to the numerical control engine bed pointing accuracy,simultaneously carried on the pitch to compensate compensates with thereverse gap, increased the numerical control engine bed.Through transforms the engine bed each precision target to conform tothe design requirement, satisfies the existing product the processingprecision request.更多还原
