毕业设计（论文）毕业设计（论文）课题类 别毕业设计说明 毕业设计总结 毕业设计论文系 科电子工程系专 业应用电子技术 应用电子技术/应用英语电气自动化技术 电气自动化技术/市场营销计算机应用技术 计算机应用技术/广告设计与策划班 级数控姓 名完成日期指导教师型腔零件的数控编程与仿真摘 要大家都知道，数控加工是目前的一门新的专业，热门专业，正在高速发展，数控加工程序是有多道复杂的程序组成的，这就为我们学习带来不便，为了使学习更方便，使用更加有条理，我编写了这份典型零件的数控铣床铣削编程与操作设计，希望为大家的工作、学习带来方便。我的这份毕业设计包括设计任务书、摘要、前言、设计说明书等多个部分。设计的主要是内容是对我们机械类加工日常加工中常见的工件取其中的一典型零件进行系统的编程与操作设计，从数控加工前应做的准备开始到数控加工工艺分析、数控刀具及其选择、工件装夹方式与数控加工夹具的选择、程序编制中的数值计算、数控加工程序的编制、数控车削加工、数控铣削加工、数控加工中心编程及自动编程技术等内容等数控加工时应注意的问题做了一一的说明。其中数控机床我们现在用的是西门子系统的，包括编程语言到是西门子系统的。由于水平有限，自己对设计的完成还不是很完善，有不足之处，希望老师斧正。Cavity parts CNC programming and simulationPickAs we all know, nc machining is now a new major, popular major, is developing rapidly, CNC programming is a multi-channel complicated procedure of composition, this is for us to learn to bring inconvenience, in order to make learning more convenient, use more structured, I wrote this typical parts of CNC milling machine, milling operation and programming design for everyones hope job, study, bring convenience.My this graduation design including the design plan descriptions, abstract, preface, the design specification and so on many parts. Design of the main content is to our machinery processing daily processing of common workpiece take one of the typical parts of program and operating system design, from the nc machining should be obtained before the start of nc machining process analysis, to the nc tool and selection, workpiece clamping fixture with nc machining way of choice, programming of the numerical calculations, CNC programming, the numerical control turning processing, CNC milling, nc machining center programming and automatic programming technology content and so on nc machining the problems needing attention when done one explanation. One numerically-controlled machine tool we use now is Siemens system, including programming language to is Siemens system. Due to the limited ability, oneself to design of complete isnt very perfect, has some shortcomings, hope the teacher know.目录1 绪论-11.1数控机床的产生与发展- 11.2数控机床的加工特点-21.3数控机床的发展趋势-42 数控铣削加工工艺-62.1零件的工艺分析-62.2装夹方案的确定-62.3数控加工刀具-72.4切削用量的确定-82.5切削液的选择-92.6进给路线的确定-9 2.6.1铣削加工路线的确定-9 2.6.2孔加工路线-112.7加工阶段的划分-122.8工序的划分-13 2.8.1 工序划分原则-13 2.8.2工序划分的方法-132.9工艺文件的制定-133 零件铣削加工工艺分析-13 3.1分析零件图，确定安装基准-133.2确定加工方法和加工路线-14 3.2.1选择加工方法-14 3.2.2选择加工路线-153.3选择切削用量-153.4选择刀具-153.5确定工件加工坐标系-153.6计算刀具轨迹坐标-
