轴零件图——材料：45，毛坯尺寸：Φ65x105数控车床轴类零件加工工艺设计及编程摘要数控技术是用数字信息对机械运动和工作过程进行控制的技术,数控装备是以数控技术为代表的新技术对传统制造产业和新兴制造的渗透形成的机电一体化产品,即所谓的数字化装备,数控技术的应用不但给传统制造业带来了革命性的变化,使制造业成为工业化的象征,而且随着数控技术的不但发展和应用领域的扩大他对归计民生的一些重要行业(IT、汽车、医疗、轻工等)的发展起着越来越重要的作用,因为这些行业所需要装备的数字化已是现代发展的大趋势.在我国加入WTO和对外开放进一步深化的新环境下,发展我国数控技术及装备是提高我国制造业信息化水平和国际竞争能力的重要性保证.数控加工与编程毕业设计是数控专业教学体系中构成数控加工技术专业知识及专业技能的重要组成部分，通过毕业设计使我们学会了对相关学科中的基本理论基本知识进行综合运用,同时使对本专业有较完整的系统的认识,从而达到巩固、扩大、深化所学知识的目的,培养和提高了综合分析问题和解决问题的能力以及培养了科学的研究和创新能力。
选这个题目的目的是它能体现出我对所学知识的掌握程度和灵活规范的运用所学知识，在我认为要成为一名合格的在学生，以自己的的思路用所学的知识来完成一份成功的毕业设计是必不可少的。
此次的毕业设计主要解决的问题是零件的装夹、刀具的对刀、工艺路线的制订、工序与工步的划分、刀具的选择、切削用量的确定、车削加工程序的编写、机床的熟练操作。
主要困难的是两次装夹中的水平Z向长度难以保证、切削用量的参数设定、对刀的精度、工艺路线的制订。
运用数控原理、数控工艺、数控编程、专业软件等专业知识和数控机床实际操作的一次综合练习，能让我感触当代科学的前沿，体验数控魅力，为人们的生活带来方便，进一步认识数控技术，熟练数控机床的操作，掌握数控，开发数控内在潜力。

First is carries on theprocessing working procedure to the work piece the determination, andcarries on the craft analysis, the attire clamps the way the choice,the cutting specifications determination. Again has carried on thechoice to the cutting tool. Then carries on the programming processingon the craft route..The current numerical control processing prioritize direction is doesnot have chart production, single unit high accuracy parallelprocessing, few people nobody melts the processing, this requestnumerical control engine bed can satisfy high speed, the high dynamicprecision, the high rigidity, the thermostability, the redundantreliability, the network as well as with it necessary control system,most importantly the mold three dimensional processingspecially paid great attention to the engine bed the dynamicperformance domestic to have some companies to introduce the highspeed milling machine, and started to apply. The domestic machine toolfactory develops some high speed milling machines one after another,and is developing high speed processes the engine bed.The numerical control technology is refers with digital, the writingand the mark composition digital command realizes or a many mechanicaldevices movement control technology. It controls usually is theposition, the angle, the speed and so on the mechanical quantity andflows to the related switch quantity with the mechanical energy. Thenumerical control production relies on data carrier and the binarymode data operation appearance. In 1908, the perforation sheet metalexchange type data carrier was published; 19 century's ends, and havethe assistance function take the paper as the data carrier the controlsystem to invent; Has established the modern computer, including computer numericalcontrol system foundation. The numerical control technology isdevelops with the engine bed control close union. In 1952, the firstnumerical control engine bed was published, becomes in the worldmechanical industry history an epoch-making event, impelled theautomated development.Has established the moderncomputer, including computer numericalcontrol system foundation.
