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。

第一章  绪论

1.1 课题研究的意义

随着科学技术的飞速发展和经济竞争的日趋激烈，产品更新的速度越来越快，多品种、中小批量生产的比重明显增加。同时，随着航空工业、汽车工业和轻工业消费品生产的高速增长，复杂形状的零件越来越多，精度要求也越来越高。此外，激烈的市场竞争要求产品研制、生产周期越来越短，传统的加工设备和制造方法已难以适应这种多样化、柔性化与复杂形状零件的高效、高质量加工要求。因此，近几十年来，世界各国十分重视发展能有效解决复杂、精密、小批量、多变零件加工的数控加工技术。在机械制造业中，大量采用以微电子技术和计算机技术为基础的数控技术，并将机械技术与现代控制技术、传感检测技、信息处理技术、网络通信技术有机地结合在一起，使其生产方式发生了革命性变化。因此研究该课题意义在于使数控技术和数控机床不断更新换代，向高速度、多功能、智能化、开放型以及高可靠性等方面迅速发发展。毕业设计小结

在这近三个月的时间里，我在导师的认真，细心的指导下，以紧张而有序的节奏顺利完成了论文工作。作者在搜索，查阅，分析有关资料的基础上，对计算机辅助制造技术有了深刻的了解，并能运用CATIA软件进行了数控加工仿真。本章下文将对作者的毕业设计做一简要小结，并讲述这个毕业设计的几点心得和体会。

1．通过作者的辛勤努力，完成了下列工作：

1）.在查阅和搜索大量与本毕业设计相关的资料的基础上，在导师的耐心指导下，完成了本次毕设的螺纹轴车削加工及数控机床的仿真，也更进一步的了解了加工工艺的流程。

2).在完成加工仿真的过程中，对各种加工参数也有了进一步的认识。

2．三个月的论文工作即将结束，至此，作者谈一下在毕业设计中的几点体会：

1).为一个即将走工作岗位的大学生，在掌握本学科，本专业的知识的基础上，要了解它们最新发展趋势。只有这样，才能跟踪国内外先进的技术知识，才能在一个高起点上进行自己的研究工作。

2).保持虚心求教的精神。现代科技的飞速发展，使一个人的能力和知识面显得极为有限，特别是目前学科内容的不断拓宽，多研究领域的交叉发展，所以，只有不断向相关领域的同仁们学习，请教，才能弥补个人知识面的不足。

3).要大胆创新，勇于开拓。传统的知识方法固然成熟，可靠，但针对集体的问题它必然有其不可弥补的缺陷，此时，我们要在仔细分析其产生缺陷原因的基础上，从中大胆提出自己富有特色的办法，这往往是解决问题的关键。

3．以后的的打算

通过这次毕业设计的锻炼，对CATIA软件和数控加工技术有了新的认识，并且初步掌握了一些CATIA加工的方法，以后会在此基础上，进一步的深化学习，以达到全面掌握。有时间的话会了解一下CATIA其他的模块，为更好地工作和幸福的生活奠定基石。

The VERICUT software system contains demonstration files that enable users to interact with VERICUT and experience various features and options. Follow the steps in this sample session to simulate milling a block（程序段） with the standard tool path file mcdblock.mcd. NOTE: This and subsequent sessions assume VERICUT has been installed with all sample files and is accessible from any directory. Sessions also assume the Toolbar is active with all groups displayed. To verify this, select 1、ViewView ToolbarToolbar SetSet AllAll. SessionSession Steps:Steps:1.1.

With default settings, VERICUT automatically loads the vericut.usr User file from the CGTech Library- a 4-axis Mazak machine and job setup. 1 If VERICUT has been started but does not have the default User file loaded, exit VERICUT, then execute VERICUT again. This should restore the default settings required to perform this sample session. Continue with step #2 below, even if the default User file did not load as expected. However, report this fact to the instructor for future consideration. 2.2.

If left as is, this could result in a broken tool or damaged fixture. There is also some red marks where a tool holder touched the part.3The Status window ErrorsErrors field reveals that VERICUT detected 9 errors during this tool path processing. VERICUT uses high resolution graphics and color shading to provide excellent visibility of the machining process, and a high quality image of the machined part. The model in VERICUT represents how the machined part would look, if actually cut by the NC machine tool. 5.5.

The cutter body removed some material while ramping in the pocket. This cutter does not cut in its center. Because the red mark is machined afterward, without the review, this error could have been missed.There is also an error where the light component collided with the Rotary Table component. This error comes from the Machine Simulation view. The machine collisions can have very dangerous repercussions. When finished reviewing the errors, select FileFile CloseClose to dismiss the Toolpath Review window. 6.6.

In this type of verification environment, you must then achieve the desired relationship between the workpiece setup and the tool path coordinate system to simulate the cutting action. This can be done by either moving the tool path coordinate system relative to the stock model, or moving the stock model relative to the tool path coordinate system - the affect in a Workpiece view is the same. This session will demonstrate how to move the models. The step at the end of the session shows how to save the session configuration in a User file so VERICUT can be quickly and easily configured to re-process the tool path file.
