汽车轴承座的数控加工 摘 要 数控技术是用数字信息对机械运动和工作过程进行控制的技术，数控装备是以数控技术为代表的新技术对传统制造产业和新兴制造业的渗透形成的机电一体化产品，即所谓的数字化装备。 本毕业论文首先介绍了数控技术的发展趋势及本论文研究的意义、背景并对课题的内容与要求进行了综合的阐述；接着阐述了复杂零件的加工工艺，其中进行了零件图的分析，说明了工件的定位、工序的确定、刀具的设计与选择以及工艺路线的制定的方法等；然后编写加工程序,并对程序进行模拟仿真，数控加工和对加工结果的检验,运用数控铣或加工中心对汽车轴承座进行加工，轴承座的加工主要包括绘制零件图、利用数控软件对零件进行造型、对零件造型进行分析并生成G代码、对G代码进行校验编辑、进行数控加工等等，最后，针对所有的内容进行总结。 关键词：加工中心；零件图；编程； 数控加工 Abstract CNC technology is the use of digital information on the mechanical movement and control of process technology, CNC numerical control technology and equipment is represented by the new technologies on traditional manufacturing industries and the penetration of new manufacturing mechanical-electrical integration products formed, the so-called the digital equipment, which cover many areas of technology: (1) machinery manufacturing technology; (2) information processing, processing, transmission technology; (3) automatic control technology; (4) servo drive technology; (5) sensor technology; ( 6) software technology. CNC technology to traditional manufacturing industries has not only brought about revolutionary changes in the manufacturing sector has become a symbol of industrialization, and along with the continuous development of digital technology and the expansion of application fields, he trades some of the important peoples livelihood (IT , automobiles, light industry, medical, etc.) the development of playing an increasingly important role, because these industries have the digital equipment is the general trend of modern development. The main subject of the use of CNC milling and machiningcenter cavity of bearing processing, the processing chamber includes plans drawn parts using CNC software to design parts of the analysis of shape parts and generate G code, the code G Edit Check for CNC machining, etc. Finally, to sum up all of the content. Keywords: machining center; parts diagram; programming; CNC machining 目 录 第1章 绪 论 4 1.1 数控发展史 4 1.2 课题意义 5 第2章 零件的分析 6 2.1 加工零件图 6 2.2几何尺寸分析 6 2
