【正文】 強(qiáng)烈。世界貿(mào)易強(qiáng)國(guó)在進(jìn)行國(guó)內(nèi)機(jī)電產(chǎn)品貿(mào)易的同時(shí)，把高技術(shù)的機(jī)電產(chǎn)品出口打入國(guó)際市場(chǎng)，作為發(fā)展出口經(jīng)濟(jì)的重要戰(zhàn)略措施，數(shù)控機(jī)床的技術(shù)水平高低及其在金屬切削加工機(jī)床產(chǎn)量和總擁有量的百分比是衡量一個(gè)國(guó)家國(guó)民經(jīng)濟(jì)發(fā)展和工業(yè)制造整體水平的重要標(biāo)志之一。隨著數(shù)控技術(shù)的不斷發(fā)展和應(yīng)用，工藝方法和制造系統(tǒng)的不斷更新，形成了 CAD、 CAM、 CAPP、 CAT、 FMS 等一系列具有劃時(shí)代意義的新技術(shù)、 新工藝的制造系統(tǒng)。數(shù)控技術(shù)的應(yīng)用將機(jī)械制造與微電子、計(jì)算機(jī)、信息處理、現(xiàn)代控制理論、檢測(cè)技術(shù)以及光電磁等多種學(xué)科技術(shù)融為一體，使制造業(yè)成為知識(shí)、技術(shù)密集的大學(xué)科范疇內(nèi)的現(xiàn)代制造業(yè)，成為國(guó)民經(jīng)濟(jì)的基礎(chǔ)工業(yè)。數(shù)控機(jī)床替代普通機(jī)床，從而使得制造業(yè)發(fā)生了根本性的變化，并帶來了巨大的經(jīng)濟(jì)效益。Manufacturing 1 第一章 緒 論 數(shù)控 技術(shù)與數(shù)控機(jī)床 數(shù)控技術(shù)是現(xiàn)代制造技術(shù)的基礎(chǔ)。 關(guān)鍵詞 ：數(shù)控銑床；進(jìn)給系統(tǒng) ； 加工 II Threedimensional Design And Manufacturing Of Feed Machanism In NC Mill Machine Tool Abstract These years,the economy of China is developing very fast which pushes the manufacturing industry to a new step as well as bringing great challenge,making it necessary to refresh the traditional mode of numerical control(NC) machine tool in stead of ordinary machine tool is one of the important ways to reach our goals,as the fomer is faster,more accurate and more the background of this,thanks to the powerfull threedimensional CAX software,it is very convenient to analyse,design and produce,pared of the traditional twodimensional this paper,after careful studying of the other NC machine tools,based on pratical requriment which has been provided by our teacher,we have designed the feed mechanism(Yoritation) of mill NC machine tool(320mm).One of the things that I’m eager to share with you is what a wonder to use UG in the process of design and the help of UG, we can produc the engineering deawing and code for production immediently after three dimensional modeling which is a great help to the in all , we can design a better machine in a shorte time. Keyword:NC Mill Machine Tool。本文就是在這樣的背景下，借助先進(jìn)的 CAX 軟件 — UG NX ，通過對(duì)其他數(shù)控機(jī)床的分析與觀察，根據(jù)實(shí)際要求，分析、設(shè)計(jì)數(shù)控銑床（ 320mm）橫向進(jìn)給系統(tǒng)。 目 錄 摘 要 ............................................................................................................................
