吉林工程技术师范学院 毕业设计 钟 鑫 2012年6月 基于CAD/CAM的 Based on the CAD / CAM a reducer NC programming and machining 专 业： 机械设计制造及其自动化 姓 名： 班 级： 机自0 学 号： 指导教师: 王桂萍 职 称： 副教授  摘 要 本设计加工工艺规程设计机械制造技术、数控编程、CAXA制造工程师和CAXA制造工程师 关键词: CAD/CAM CAXA制造工程师、工艺规程、、 Abstract This design will be used CAXA drawing software reducer manufacturing and process planning, integrated use of the product machinery manufacturing technology, CNC programming, CAXA manufacturing engineers, and other courses related to the theory and production of practical knowledge to analyze and solve reducer designand professional knowledge to further consolidate and deepen. Further half of the learning process planning, the ability to understand and master the commonly used method of calculation, to develop the correct design thinking and analysis, problem solving, in particular, the overall design and computing power. Learn how to use computing and graphics standards, manuals, Atlas, and access to the relevant technical information, training the basic skills of process design. CAXA manufacturing engineer is not only an efficient and easy to learn, has a good process of NC programming software, but also a set of Windows original style, and powerful 3D modeling, surface entities perfect combination of CAD / CAM integration software. The CAXA manufacture the postprocessor engineers do not need to generate the intermediate file can be directly output the G code instructions. The system can not only provide the CNC system set format, users can also customize the definition of special NC system processing format.
