ferred to as NC (NC), developed a kind of modern automation technology is the use of digital information to achieve a method of control of machinery and equipment.With the continuous development of science and technology, the munity has increasingly stronger demands for product diversification, product upgrading Panda faster, multispecies, a marked increase in the proportion of small and medium volume production, plexshaped parts, more and more the more precision to the higher. In addition, the intense petition in the market demands shorter and shorter product development cycle, the traditional processing equipment and manufacturing methods are difficult to adapt to this diversity, flexible highperformance parts with plex shapes, highquality processing requirements. Thus, in recent decades, can effectively solve the plex, sophisticated, small batch processing problems and everchanging parts CNC machining technology has been rapid development and wide application ofManufacturing technology to make fundamental changes have taken place.Key words: numerical control technology目 錄引 言 5 5 數(shù)控加工技術(shù)概況 5 數(shù)控技術(shù)的特點 5 數(shù)控機床的加工原理 6 數(shù)控加工技術(shù)的主要應用對象 6 數(shù)控技術(shù)的發(fā)展趨勢 62.數(shù)控加工工藝 7 數(shù)控加工工藝概述 7 數(shù)控加工工藝的特點 7 數(shù)控加工工藝的主要能容 7 數(shù)控機床的合理選用 7 控加工工藝分析與工藝設計 7 控加工工藝分析 7 數(shù)控加工工藝設計 83.數(shù)控編程基礎 8 程序格式 8 程序段的格式和組成 8 程序號 8 坐標字的表示方式 8 數(shù)控程序的指令代碼 94.數(shù)控車床實例應用 9 工藝方案訂制 10 程序設計 10結(jié)束語 12謝 辭 13參考文獻 14引 言數(shù)字控制簡稱數(shù)控,是近代發(fā)展起來的一種自動控制技術(shù),是用數(shù)字化信息實現(xiàn)機械設備控制的一種方法。此外,激烈的市場競爭要求產(chǎn)品研制生產(chǎn)周期越來越短,傳統(tǒng)的加工設備和制造方法已難于適應這種多樣化、柔性化與復雜形狀零件的高效,高質(zhì)量加工要求。==========機電工程學院機電一體化專業(yè)畢業(yè)論文復雜零件加工工藝設計及數(shù)控編制學生姓名:=====學 號:=====專 業(yè):機電一體化指導老師:=====完成時間:2012年4月摘 要數(shù)字控制(number control)簡稱數(shù)控(NC),是近代發(fā)展起來的一種自動控制技術(shù),是用數(shù)字化信息實現(xiàn)機械設備控制的一種方法。隨著科學技術(shù)的不斷發(fā)展,社會對產(chǎn)品多樣化的要求日益強烈,產(chǎn)品更新?lián)Q代悅來越
