配合件的工艺与编程
【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。
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。

Abstract: Numerical control technique is to use the technique that the figure information carries on a control vs machinery running and the operate process, count control an equipage is with the number control technique for the representative's new technique make the machine electricity integral whole that domain and newly arisen manufacturing permeate forming to turn a product to the tradition, namely the so-called digitize equips. The number controled technical application to not only bring traditional manufacturing business revolution change, make the manufacturing business become the symbol of industrialization, but also along with number control technical not only expanding of shape and application realm his some shapes of important crafts(IT, autocar, medical treatment and light work etc.) in returning to account people's livelihoods contain more and more important action, because these crafts is already the big trend of modern shape the digitize that need to be equiped. Deveolp an our country number under the new surrounding that our country building - out WTO with outward open to deepen further control technique and equipage is exaltation our country importance assurance of the manufacturing
business
information-based
horizontal
and
international competitive power. The number controls transform and plait distance to graduate a design is number control to constitute number to control the important composition of processing technology professional knowledge and professional skill fraction in the professional teaching system, the design of passing the graduation makes the basic theory that we learned vs related academics basic knowledge progress synthesis usage, make at the same time the understanding to have more complete system to this profession, thus hit consolidation and expand, deepen the purpose of learning the
knowledge, development and exaltation comprehensive analysis problem and problem-solving capability and development the search and innovation capability of science.
This time graduation's designing the problem of main settle is the packing of kit clip, tool angel of for establishing knife, craft route, the sequence tread with work of the select of curtate, tool angel, slice to pare dosage to really settle, the well-trained operation of writing of truning job program, engine bed.
