凸轮杆工艺及加工程序编制
摘要：本文主要介绍了凸轮杆工艺及加工程序编制。本文作者是在保证产品质量、提高生产率、降低成本、充分利用现有生产条件、保证工人具有良好而安全劳动条件的前提下进行设计的。在工艺设计中，作者结合实际进行理论设计，对凸轮传统生产工艺进行了改进，优化了工艺过程，使凸轮的生产加工更经济、合理。在程序设计部分，作者在收集加工所用机床、刀具及辅助工具等有关资料后，对工件材料、结构特点、技术要求及工艺分析的基础上，按照程序编制步骤设计出符合凸轮生产工艺及夹具制造要求的程序。

Cam Lever technoLogy and processing program
Abstract:This paper mainLy introduces the cam Lever technoLogy and processing program. The author of this paper is to ensure product quaLity, increase productivity, reduce the cost, make fuLL use of the existing conditions of production, ensure worker to have good working conditions under the premise of safety design. In process design, the author makes theoreticaL design of cam, the traditionaL production process was improved, the optimization process, the production process of cam is more economicaL, reasonabLe. In the program design part, the author used in coLLecting machine, tooL and tooL and other reLevant data, on the basis of the workpiece materiaL, structure characteristics, technicaL requirements and process anaLysis, in accordance with the programming steps designed in Line with the cam production process and fixture manufacturing requirements of the program.
