Process design is good or bad, will not only play the machine tool efficiency, but also directly affect the mac hining quality. Therefore, research on numerical control processing technology to improve the accuracy of the processed parts, improve efficiency, thereby enhancing the economic efficiency of enterprises is very necessary. With the CAD / CAM technology, rapid development, so businesses can process more precise, more plex shape parts. On the other hand increasing petition in the market, requires enterprises to improve product quality continuously pressed without sacrificing production time. Therefore, the use of puter numerical control machining process planning on the auxiliary, in order to improve the NC machining process design quality, reduce production time to bee a top priority. In NC for reasonable choice of cutting parameters to ensure product quality, increase productivity, reduce production costs play an important role. In recent years, with the widespread application of CNC technology, and a variety of advanced manufacturing technology, rapid development, production assistant time reduced significantly. Therefore decrease the cutting time, and plays an important role in increasing productivity. At present, most factories in the production of cutting experience or reference manual to select the cutting parameters, which often reach the most optimized cutting parameters. Use of modern cutting theory, mathematical modeling and model analysis for the optimal bination of cutting parameters, cutting parameters is an important direction. The design on the traditional processing technology and CNC machining technology main content, process problems, parts diagram analysis, process and equipment selection, process planning, process development and other aspects routes were introduced simultaneously a number of examples of the machining process and parison of traditional V processing technology. CNC machining process made more efficient than traditional processing technology of high precision and accuracy than conventional processing, processing, CNC machining process of plex product applications can reduce the cost point of view, provide a reference for the selection of processing technology. Keywords: traditional processing technology, CNC machining technology, Technological features, process the content. 第 1 頁(yè) 共 38 頁(yè) 第一章 緒論 數(shù)控加工工藝使傳統(tǒng)的加工工藝在多方面產(chǎn)生很大的影響 ,數(shù)控加工工藝使工人的勞動(dòng)強(qiáng)度下降,提高了加工效率,對(duì)傳統(tǒng)加工工藝與數(shù)控加工工藝進(jìn)行比較對(duì)我們的生產(chǎn)有重要意義,合理確定數(shù)控加工工藝,對(duì)實(shí)現(xiàn)優(yōu)質(zhì)、高效的數(shù)控加工有重要作用,所以必須了解這些差別 ,才能很好地利用數(shù)控加工方式 ,保證加工過(guò)程順利和加工質(zhì)量穩(wěn)定。數(shù)控系統(tǒng)由當(dāng)初的電子管式起步,經(jīng)歷了以下幾個(gè)發(fā)展 階段:分立式晶體管式 — 小規(guī)模集成電路式 — 大規(guī)模集成電路式 — 小型計(jì)算機(jī)式— 超大規(guī)模集成電路 — 微機(jī)式的數(shù)控系統(tǒng)。特點(diǎn)是具有很多硬件電路和連接節(jié)點(diǎn),電路復(fù)雜,可靠性不好。 我國(guó)對(duì)數(shù)控機(jī)床的研制和發(fā)展起始于 50 年代,并于 60 年代末 70 年代初研制成功劈錐數(shù)控銑床、 CJK 一 18 晶體管數(shù)控系統(tǒng)及 X53K 一 lG 立式數(shù)控銑床等。我國(guó)在二十世紀(jì)八十年代初期通過(guò)引進(jìn)、消化、吸收國(guó)外的先進(jìn)技術(shù)。又在“七五”、“八五”、“九五”期間對(duì)伺服驅(qū)動(dòng)技術(shù)進(jìn)行重大科技項(xiàng)目攻關(guān),取得了重大成果。目前,我國(guó)的 機(jī)床工業(yè)正從生產(chǎn)大國(guó)逐漸變?yōu)闄C(jī)床強(qiáng)國(guó),主要體現(xiàn)在數(shù)控機(jī)床產(chǎn)品的技術(shù)水平和質(zhì)量不斷發(fā)展和提高。由于科學(xué)技術(shù)人員的不懈努力,新的數(shù)控產(chǎn)品不斷涌現(xiàn),如多坐標(biāo)軸高速高精度等數(shù)控機(jī)床的研制成功??傊乱淮鷶?shù)控系統(tǒng)技術(shù)水平大大提高,促進(jìn)了數(shù)控機(jī)床性能向高精度、高速度、高柔性化方向發(fā)展,使柔性自動(dòng)化加工技術(shù)水平不斷提高。數(shù)控技術(shù)向高速化、高精度、多軸控制和復(fù)合方向發(fā)展,向模塊化、可重構(gòu)、可擴(kuò)充的軟硬件系統(tǒng),這就是開(kāi)放式控制系統(tǒng)。在激烈的市場(chǎng)競(jìng)爭(zhēng)中,各企業(yè)總結(jié)前期低水平和無(wú)序競(jìng)爭(zhēng)造成的產(chǎn)品質(zhì)量低下,損失市場(chǎng)的沉痛經(jīng)驗(yàn),迫切需要成本低、效率高、技術(shù)含量高的新型設(shè)備來(lái)武裝自 己,以增強(qiáng)其產(chǎn)品的競(jìng)爭(zhēng)力、提高企業(yè)的知名度。 本論文研究的主要內(nèi)容 基于查閱大量資料的前提下,了解數(shù)控機(jī)械加工工藝的數(shù)字化: 了解傳統(tǒng)加工工藝 了解數(shù)字化加工工藝(電腦、單片機(jī)的實(shí)際應(yīng)用) 選擇某一具體加工方式進(jìn)行數(shù)字與傳統(tǒng)的比較 今后的發(fā)展趨勢(shì)、新技術(shù)的應(yīng)用等 第 3 頁(yè) 共 38 頁(yè) 第二章 傳統(tǒng)加工工藝 傳統(tǒng)加工工藝,就是使用普通機(jī)床加工零件時(shí)所運(yùn)用的各種工藝方法和工藝手段。工藝是指制造產(chǎn)品的技巧、方法、和程序。它包括毛坯制造、零件加工、熱處理、質(zhì)量檢驗(yàn)和機(jī)器裝配等。通常 ,機(jī)械加工
