文档介绍：I 本科毕业设计论文题目: 配合件数控加工工艺分析与仿真 I 摘要数控编程是一种可编程的柔性加工方法,它的普及大大提高了加工效率。但是在加工技术方面,除要求数控机床具有较强的运动控制能力之外,更重要的是如何有效地获得高效优质的数控加工程序,并从加工过程整体上提高生产效率。由于零件复杂性的增加,而且工人技术水平有限,手工编程越来越困难。应用数控编程可大大提高生产率、稳定加工质量、缩短加工周期、增加生产柔性、实现对各种复杂精密零件的自动化加工,易于在工厂或车间实行计算机管理,使车间设备总数减少、节省人力、改善劳动条件,有利于加快产品的开发和更新换代,提高企业对市场的适应能力并提高企业综合经济效益。本文以为工具,完成了配合件三维造型及仿真加工。内容包括: 首先, 根据配合件的结构特点和技术要求, 在对其进行加工工艺分析之后, 确定了零件的加工方法。然后,利用 UG/CAD 模块完成了零件几何体的参数化建模。在此基础上,利用 UG/CAM 模块进行数控编程,设计了加工路线、***轨迹,切削方式等工艺参数,生成了零件的 NC程序。关键词:,三维建模,加工仿真, UG 软件 II C machining isa programmable flexible processing methods, its popularity greatly improve the processing efficiency. But in the processing technology, in addition to requirements C machine tools has a strong ability to control movement and, more importantly, how to efficiently obtain high-C machining process, and from the process asa whole to improve production efficiency. As part of the plexity and limited skills of workers, manual programming more difficult. CNC machining applications can greatly improve productivity, stability, processing quality, shorten the processing cycle, increasing the production of flexible, to achieve a variety plex ponents for the automation of processing, easy to implement ina factory or puter management, reducing the total number of workshop equipment, saving manpower, improve labor conditions, help speed up product development and upgrading, and improving the ability of the market to adapt and improve their overall economic efficiency. In this paper, UG NX a plete the adjust frame three-dimensional modeling . Include: First, based on the adjusted frame structural features and technical requirements, in its process analysis, to determine the part of the processing methods. Then, using UG / CAD module plete the part geometry parametric modeling. On this basis, the use of UG / CAM module for NC programming, design the machining line, the tool path, cutting mode and other parameters, to generate a part of the NC program. KEYWORDS : CNC technol
