基于西门子802C数控系统开发数控车床实训台
摘 要
随着科学技术的不断进步设社会生产力的不断断发展，以数控技术为基础的先进制造技术正以较快的速度逐步取代传统的机械制造技术 ,这已成为当今机械制造技术发展的趋势。数控机床在制造业中的大量应用 ,使社会对能熟练掌握数控机床的操作 ,编程及维修的工程应用人才的需求量越来越大 。近年来各院校相应开出的数控专业 ,便从教育的层面上反映出社会的这种需求。然而这也向我们提出了数控教学如何培养适应工程应用的数控人才的问题 。数控人才的培养离不开实践操作，而现今真正投入生产的数控设备价格一般都很昂贵，因此研究和开发一套用于经济适用的数控仿真实训台就变得很有必要。
本设计是基于西门子公司的SINUMERIK 802C数控车床实训台开发设计，首先应了解和掌握了西门子802C数控系统的结构、工作原理、控制方式等知识后根据它配备伺服系统、主轴控制系统和辅助运动控制系统，通过查阅资料对车床实训台的硬件进行选择，了解各个模块的工作原理，并设计外部硬件线路，最终设计出能完成演示主轴控制、进给运动控制、辅助装置控制等功能，符合学校教学实际需求的专用实验设备。不仅可作为数控车床电气故障的维修实训设备，也可作为数控车床的实际加工操作实训设备。该装置可以使学生掌握数控车床系统控制原理、电气设计方法、元器件的选择、车床电气安装及调试、故障诊断维修、零件程序编制及图形模拟加工过程等多项实验内容，达到工业生产现场实习效果。操作过程与实际生产接轨，而且经济实用，不仅解决了学员培训费用高的问题，而且更能体现仿真操作的真实性，使教学效果得到明显提高。

Based on simens 802C CNC system development training sets CNC lathe
Abstract：With the continuous progress of science and technology set ever-breaking development of social productive forces，advanced manufacturing technology is based on the numerical control technology at a faster rate gradually replaced the traditional mechanical manufacturing technology，which has become the trend of mechanical manufacturing technology development．CNC machine tool used in manufacturing industry, enabling the community to skilled in CNC machine tool operation，programming and maintenance of engineering application talents demand is growing．In recent years the institutions appropriate to write NC professional，from the level of education reflects this demand of the community．But it also put forward to us how the teaching of numerical control training project on the application of numerical control talents．CNC talents training cannot be separated from practice，and today the real production of CNC equipment prices are generally very expensive，so research and development of a system for economical numerical control imitating real training will become necessary．
This design is based on Siemens company of SINUMERIK 802C NC lathe real training Taiwan development design，first should has solutions and master has Siemens 802C NC system of structure，and work principle, and control way, knowledge Hou under it equipped with servo system，and spindle control system and secondary movement control system，by inspection information on lathe real training Taiwan of hardware for select，understanding each module of work principle，and design external hardware line，eventually design out can completed demonstrates spindle control，and into to movement control，and secondary device control，function，meet school teaching actual demand of dedicated experimental device．Not only can be used as electrical faults of NC lathe repair training equipment，or as actual machining of numerical control lathe operation training devices．The appliance can make students master the electrical
