数控加工实习 毕业论文.docVIP

本科毕业论文（设计） 题　　目 数控加工实习报告 学生姓名　 贾 飞 专业名称　 机械设计制造及其自动化 指导教师　 梁 磊 实习地点 宝鸡技师学院 2013 年5月 22 日 数控车床实习报告 摘要：控加工，也称之为NC（Numerical Control）加工，是以数值与符号构成的信息，控制机床实现自动运转。数控加工的最大特征有两点：一是可以极大地提高精度，包括加工质量精度及加工时间误差精度；二是加工质量的重复性，可以稳定加工质量，保持加工零件质量的一致。通过本次实训，使我对数控机床得到了很大的认识，数控机床不仅功能强大，而且很实用，只要输入正确的程序，它就可以通过机床车出你想要的工件来，之前我对数控这门知识掌握的还不够，通过这次实训的学习，可以说，一些简单的工件加工对我来说不算什么，信手拈来；学习的具体内容有：数控操作安全知识模块； 操作面板模块；开关机、回参考点及其他基本操作模块；程序编辑模块；手动车削工件模块；对刀模块；加工模块： 给定程序加工工件的基本表面（车端面、车外圆、车沟槽、车锥度、车单线螺纹、车多线螺纹、车锥度螺纹、车凸圆弧、车凹圆弧，车圆球等）；轴类零件加工；螺纹类零件加工；套类、盘类零件加工；特形面类零件加工；综合类零件加工。 关键词：刀库 程序 操作 CNC lathe practice reportAbstract: numerical control processing, also known as NC (Numerical Control) processing, is constituted by the numerical and symbolic information, realize the automatic operation control of machine tool. There are two main characteristics of NC machining: one is can greatly improve the accuracy, including error precision machining quality and accuracy and processing time; two is the repetitive machining quality, stable machining quality, machining parts, maintain consistent quality. Through this training, bring me a lot of knowledge obtained for CNC machine tools, CNC machine tool is not only powerful, but very practical, as long as the input the correct procedure, it can pass through the machine parts you want to, before I to control this knowledge is not enough, through the training of learning, can say, some simple machining means nothing to me, have ones words at hand; the specific content of learning: NC operation safety knowledge module; operation module; the switch machine, back to the reference point and other basic operation module; program edit module; manual cutting tool module; modules; processing module: basic surface 1 of the given program the workpiece (car end, turning, trench, tapering, car sin
