摘 要
随着全球制造业竞争的日益激烈，先进制造技术的不断出现，现代数控加工技术的普遍应用，使得产品的加工周期大幅度缩短，产品的加工质量不断改善，加速了产品的更新换代，增强了产品的竞争力。因此数控加工技术的研究已成为研究重点。
在这个计算机技术发展迅速，新科技日新月异的信息社会中，制造业也发生着革命性的变化。计算机模拟、仿真技术省去了大量的工作量，大大节约了原材料成本，提高了生产效率。工厂里现在大部分机床使用的都是数控机床，数控加工出来的零件既符合外观及精度有要求，又方便操作者进行操作。掌握计算机制造技术已经是新时代我们势在必行的必须课。
作者在查阅和搜索大量与本毕业设计相关资料的基础上，对数控加工进行研究，并在老师的耐心指导下，首先分析零件模型，根据零件的外形特点，确定加工方法。利用CATIA P3 V5R20进行数控加工程序的编制，设计出该零件的NC加工方法，并且尝试找出最合理的加工方法。从而进行零件的动态模拟数控加工。此次设计中以螺纹轴为加工对象，利用粗车，精车，切空槽，切沟槽，钻孔，钻螺纹孔等进行加工。最后，结合CATIA中设计好了的模型实例展现了VERICUT环境下数控加工仿真的全过程。

ABSTRACT
Since the competition of global manufacturing industry is increasingly intense, advanced manufacturing technologies appeared continuously. The general application of the modern Numerical Control Manufacturing technology, has made the processing cycle of the products shorten by a large margin, has improved the processing quality of the products, has accelerated the update of the products, and has strengthened the competitive power of the products. So the research of the process technology of numerical control has become the focal point of studying.
The manufacturing method changes a lot with the development of the computer technology in the modern society. Computer simulation saves a lot of time for the workers and greatly saves the cost of raw materials. Also computer simulation increases production efficiency. At present, most of the factory machines are used in CNC machine tools. CNC machining parts achieved the requirement both in the appearance and in the accuracy. To master the computer manufacturing technology for the engineering working in the field of aviation is imperative.
After looking up plenty of relevant articles, author researched the process technology of Numerical Control. Under the guidance of the teacher's patience，author analysis the mold of the part at first and according to the shape characteristics of parts , assure the method of processing. Finally utilized CATIA P3 V5R20 carrying on characteristic modeling and carry on Numerical Control establishment to process procedure and designed NC processing method of the part and try to find out the most reasonable method of processing .Thus the dynamic simulation Numerical Control of carrying on the part is processed. Regarding thread spindle as the target of processing in this design . author has used Rough Turning operation, Profile Finish Turning operation, Recess Turning operation, Groove Turning operation, Drilling, Reverse Threading. Further，the whole process of NC simulation under VERICUT is shown combining with designed model instance in CATIA．
