XXXXXXXXXX学院 毕业设计（论文） 题 目 游戏手柄的凸凹模的加工 系 机械及自动化系 专 业 数控专业 班 级 姓 名 指导教师 年 月 日 摘要: 随着科学技术飞速发展和经济竞争的日趋激烈, 机械产品的更新速度越来越快，数控加工技术作为先进生产力的代表, 在机械及相关行业领域发挥着重要作用,机械制造的竞争, 其实质是数控技术的竞争. 本次设计就是进行数控加工工艺设计及零件的加工, 侧重于设计该零件的数控加工夹具, 主要设计内容有: 完成该零件的工艺规程 ( 包括工艺过程卡、 工序卡和数控刀具卡 ) 和主要工序的工装设计. 并绘制零件图、夹具图. 用G代码编制该零件的数控加工程序, 在则学习计算机辅助工艺设计 (CAPP) 相关知识, 并编制其构架. 其中此次毕业设计中的工装设计中的工装夹具是重点和难点. 关键词: 数控加工、机床夹具、数控编程、计算机辅助工艺. Abstract: With the rapid development of science and technology and increasingly fierce economic competition, mechanical products, faster updates, digital processing technology as a representative of the advanced productive forces in the field of machinery and related industries are playing an important role, machine building competition , Is the essence of NC technology. This is designed for CNC machining process planning and parts processing, focusing on the design of the CNC machining parts of the fixture, and design are as follows: the completion of parts of the Process (including the process Process cards, process cards and card cutter NC) and the major re-tooling of the design. Rendering and parts map, chart fixture. G code with the preparation of the parts of the CNC machining process, while learning computer aided process planning (CAPP) related Knowledge, and the preparation of the framework. In which the graduate design tools in the design of the fixture is the emphasis and difficulty. Key words: CNC Machining, machine tool fixture, NC programming, computer-assisted technology. 目 录 一．开题报告··························································2 二．前言································································3 设计书明书 一．毕业设计任务书·····················································4 工件的零件图和其凸凹模零件图···································4 工序安排··························································6 综合工艺过程卡·········································
