多功能組合機(jī)床美國密歇根大學(xué)菲利普摘要:總的機(jī)床加工中心需求的變化,這可能會(huì)導(dǎo)致加工制造業(yè)不斷變化,采用有效的勞動(dòng)力集中,并在全球范圍內(nèi)提高市場競爭力。關(guān)鍵詞:關(guān)于多功能組合機(jī)床組成機(jī)床工具在工業(yè)領(lǐng)域有許多名稱來形容,類似“多任務(wù)處理裝置”,“多功能引擎床”,“多步驟生產(chǎn)制度“等,它可被稱為真正加工領(lǐng)域的新星,可降低成本,簡化配置,因此美國只繼續(xù)保留在境內(nèi)生產(chǎn)。在過去,只有用多機(jī)操作才能完成的任務(wù),現(xiàn)在可以集中過程,以一臺(tái)機(jī)床完成。由于市場需求的不斷變化,產(chǎn)品生命周期不斷縮短,市場競爭加劇,今天的市場需要多任務(wù)分期付款的概念。隨著精藝管理的推出,整個(gè)生產(chǎn)環(huán)境,由不集中的零件加工到機(jī)器上集中一次得以完成。一些傳統(tǒng)的制造業(yè)廠商認(rèn)為多功能組合機(jī)床,工具過于復(fù)雜,很難找到合適的營辦商,主要原因是缺少對工作的基本原則,工序復(fù)雜,現(xiàn)場和生產(chǎn)車間相關(guān)創(chuàng)新,機(jī)床使用的解決方案等方面的培訓(xùn)。直覺型技術(shù)控制設(shè)備使用“帶走熱量”式設(shè)計(jì),不同的材料,床身,鋼制直線滾動(dòng)導(dǎo)軌的鋼制周轉(zhuǎn)箱鞍和設(shè)備的使用,使所有這些設(shè)備結(jié)合在一臺(tái)機(jī)床。其中,熱傳導(dǎo)和體積膨脹是相互影響的。所有不同大小的東西有不同的體積增長速度。由于這一原因,需要做的是認(rèn)識(shí)發(fā)熱在哪里,可以通過合理的補(bǔ)償解決機(jī)床設(shè)計(jì)中的薄弱點(diǎn),實(shí)現(xiàn)柔性機(jī)床。該部分是整個(gè)行程的運(yùn)動(dòng)。機(jī)床滑動(dòng)會(huì)產(chǎn)生激烈摩擦和變形。熱加工生產(chǎn)的進(jìn)程進(jìn)行到不同的階段,可以混合制冷劑在整個(gè)過程中,并且機(jī)床將提交??一份關(guān)于刀具的不同溫度承受范圍,因此也有許多工序都受到熱穩(wěn)定性的影響。隨著切削刀具技術(shù)轉(zhuǎn)向多功能組合機(jī)床,它就成了具備銑削和切削功能的“多功能機(jī)床”。據(jù)資料記載,這些機(jī)床最顯著的特點(diǎn)是智能的。由于防碰撞保護(hù)技術(shù)已經(jīng)成熟,在某些情況下,立即采用手動(dòng)操作模式,就可避免發(fā)生的沖突。由于控制軟件有很好的及時(shí)性,用戶操作界面也在不斷完善。相信多功能組合機(jī)床將應(yīng)用于世界各地制造業(yè),在更多不同的加工場景中,離線編程優(yōu)化和數(shù)控全自動(dòng)控制系統(tǒng)的形成已經(jīng)使得這項(xiàng)技術(shù)更加易于接受,所以當(dāng)使用程序時(shí),機(jī)床并不需要花很多時(shí)間調(diào)試運(yùn)行程序,并能夠確認(rèn)修改部分沒問題。如果組件需要提供高,低兩個(gè)旋轉(zhuǎn)拖具同時(shí)進(jìn)行粗加工,在這種情況下的編程是相當(dāng)困難的,因?yàn)樗枰獌蓚€(gè)旋轉(zhuǎn)拖具不斷橫向進(jìn)給。該系統(tǒng)可以反饋AdMac刀架自動(dòng)編程的同時(shí)并能給出所有參數(shù)對應(yīng)正確的主軸速度,進(jìn)給量,而且實(shí)現(xiàn)了同步。大隈公司的防碰撞系統(tǒng)設(shè)計(jì)基于實(shí)際加工經(jīng)營和防碰撞模擬技術(shù),因此,如果該公司已安裝了錯(cuò)誤的切削工具或建立了錯(cuò)誤的參數(shù),控制系統(tǒng)將進(jìn)行檢查,防止機(jī)床進(jìn)入加工。通過與西門子合作,INDEX公司可提供三維圖案現(xiàn)顯示”虛擬機(jī)床”,并已定制一些特定型號(hào)的機(jī)床于程序中。研究結(jié)果表明,模擬過程不僅制作的零件和產(chǎn)品的實(shí)際最終是相似的,而且是一對一個(gè)的模擬仿真。直觀式控制界面,仿真以及其他軟件技術(shù)的進(jìn)步,更多的生產(chǎn)車間已經(jīng)愿意趨向多功能組合機(jī)床加工,但如果機(jī)床生產(chǎn)商沒有相應(yīng)的知識(shí)培訓(xùn)和解決現(xiàn)場突發(fā)問題的能力,制造商也很難充分利用先進(jìn)機(jī)床靈活性方面的優(yōu)勢。機(jī)器做的工作越多,機(jī)器將越復(fù)雜,同時(shí)也需要有較強(qiáng)相應(yīng)技能的人才能來操作。在過去,如果機(jī)械師一天可以生產(chǎn)3臺(tái)機(jī)床組件,那么現(xiàn)在他有這樣一個(gè)多功能機(jī)床,可能會(huì)產(chǎn)生更多的組件。更重要的是,他可以借助相關(guān)軟件的幫助,促使生產(chǎn)效率更高,零部件加工過程簡化,也可以確立加工工藝方案。由于需要更換3主軸部件,因此在更換之前,車間應(yīng)處理盡可能多的組件。由于多用途引擎床轉(zhuǎn)換組件速度快,所以生產(chǎn)批量的時(shí)間間隔較短,生產(chǎn)效率較高。經(jīng)過關(guān)于能否廣泛的使用多功能組合機(jī)床的一些研討會(huì)的召開,大家很快發(fā)現(xiàn)各種功能之間是統(tǒng)一的。過去一個(gè)車間可能要用一個(gè)操作者,一個(gè)調(diào)解人員,一個(gè)編程人員,現(xiàn)在這三個(gè)不同的工作完全可以由一個(gè)人來做。相比傳統(tǒng)的工藝中,機(jī)械師將由一名工程師來擔(dān)當(dāng),如果該工程師熟悉零件的加工工序,這將是更理想的。對于這種轉(zhuǎn)變,培訓(xùn)將更加簡單,就像火車只有一個(gè)方向而不是三個(gè)方向。從長遠(yuǎn)來看,這也將提高操作員對該職位的滿意度。當(dāng)工程師在做規(guī)劃時(shí),將會(huì)更加注重零件加工的全過程,完成全過程控制。此外,他還需要努力向刀具使用和工藝規(guī)劃方面發(fā)展,還要做出任何型號(hào)的多功能組合機(jī)床的工具,因此,車間需要提供熟練的機(jī)械師,他要有能力完成多種靈活的操作。所以,橫向培訓(xùn)比以往任何時(shí)候都重要,機(jī)械加工中將銑,車視為完全不同學(xué)科的觀點(diǎn)將不再了。對于程序員來說,這是屬于他自己的時(shí)間,誰編的程序,誰就會(huì)明白機(jī)床的功能,誰就能完全操作它,這就是編程人員的個(gè)人能力了。生活中大多數(shù)人不會(huì)選擇把普通轎車的輪胎用在賽車上,但是工藝師選擇刀具時(shí)卻是可以的。可能大家認(rèn)為新的機(jī)床應(yīng)配以新的刀具,否則舊的刀具將會(huì)影響新的機(jī)床加工效率,但是為了配合多功能組合機(jī)床,新的刀具和刀具適配技術(shù)也已經(jīng)開發(fā),目前工業(yè)領(lǐng)域開發(fā)的新加工刀具,可
