【正文】 1 / 36配合件的工藝與編程【摘要】數(shù)控技術是用數(shù)字信息對機械運動和工作過程進行控制的技術,數(shù)控裝備是以數(shù)控技術為代表的新技術對傳統(tǒng)制造產(chǎn)業(yè)和新興制造的滲透形成的機電一體化產(chǎn)品,即所謂的數(shù)字化裝備。數(shù)控技術的應用不但給傳統(tǒng)制造業(yè)帶來了革命性的變化,使制造業(yè)成為工業(yè)化的象征,而且隨著數(shù)控技術的不但發(fā)展和應用領域的擴大他對歸計民生的一些重要行業(yè)(IT、汽車、醫(yī)療、輕工等 )的發(fā)展起著越來越重要的作用,加入 WTO 和對外開放進一步深化的新環(huán)境下 ,發(fā)展我國數(shù)控技術及裝備是提高是數(shù)控專業(yè)教學體系中構成數(shù)控加工技術專業(yè)知識及專業(yè)技能的重要組成部分，通過畢業(yè)設計使我們學會了對相關學科中的基本理論基本知識進行綜合運用,同時使對本專業(yè)有較完整的系統(tǒng)的認識,從而達到鞏固、擴大、深化所學知識的目的,培養(yǎng)和提高了綜合分析問題和解決問題的能力以及培養(yǎng)了科學的研究和創(chuàng)新能力。此次的畢業(yè)設計主要解決的問題是零件的裝夾、刀具的對刀、工藝路線的制訂、工序與工步的劃分、刀具的選擇、切削用量的確定、車削加工程序的編寫、機床的熟練操作。關鍵詞： 數(shù)控車、工藝分析、加工方案、2 / 36Abstract: 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 representative39。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 socalled digitize equips. The number controled technical application to not only bring traditional manufacturing business revolution change, make the manufacturing business bee 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 people39。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 informationbased horizontal and international petitive power. The number controls transform and plait distance to graduate a design is number control to constitute number to control the important position 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 plete system to this profession, thus hit consolidation and expand, deepen the purpose of learning the knowledge, development and exaltation prehensive analysis problem and problemsolving capability and development the search and innovation capability of science.This time graduation39。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 welltrained operation of writing of truning job program, engine bed.Key words: CNC lathe、Process analysis 、Processing scheme目錄3 / 361 數(shù)控機床的發(fā)展簡介 ...................................................................................................................52 數(shù)控加工工藝的基本知識 ...........................................................................................................7 數(shù)控加工工藝的概念 .............................................................................................................7 數(shù)控加工工藝過程 .................................................................................................................7 數(shù)控加工的特點 .....................................................................................................................73 零件數(shù)控加工前的簡單分析 .......................................................................................................8 零件的基本情況簡介 .............................................................................................................8 零件的技術要求 .....................................................................................................................9 加工設備的選擇 .....................................................................................................................9 零件的工藝分析 .....................................................................................................................9 基準的選擇原則 ...................................................................................................................104 零件數(shù)控加工工藝分析 .............................................................................................................13 加工方案的確定 ...................................................................................................................13 工步的劃分 ...........................................................................................................................13 加工順序及進給路線的確定 ..........................................................................
