模具高速銑削加工技術(shù)概述

附件：模具高速銑削加工技術(shù)摘要介紹了高速銑削在模具加工中的應(yīng)用以及影響，并簡(jiǎn)要的介紹了高速銑削機(jī)床的結(jié)構(gòu)、控制系統(tǒng)和刀具。對(duì)高速加工的工藝進(jìn)行了簡(jiǎn)單的分析。關(guān)鍵詞高速銑削；模具加工前言在現(xiàn)代模具生產(chǎn)中，隨著對(duì)塑件的美觀度及功能要求得越來(lái)越高，塑件內(nèi)部結(jié)構(gòu)設(shè)計(jì)得越來(lái)越復(fù)雜，模具的外形設(shè)計(jì)也日趨復(fù)雜，自由曲面所占比例不斷增加，相應(yīng)的模具結(jié)構(gòu)也設(shè)計(jì)得越來(lái)越復(fù)雜。這些都對(duì)模具加工技術(shù)提出了更高要求，不僅應(yīng)保證高的制造精度和表面質(zhì)量，而且要追求加工表面的美觀。隨著對(duì)高速加工技術(shù)研究的不斷深入，尤其在加工機(jī)床、數(shù)控系統(tǒng)、刀具系統(tǒng)、CAD/CAM軟件等相關(guān)技術(shù)不斷發(fā)展的推動(dòng)下，高速加工技術(shù)已越來(lái)越多地應(yīng)用于模具型腔的加工與制造中。數(shù)控高速切削加工作為模具制造中最為重要的一項(xiàng)先進(jìn)制造技術(shù)，是集高效、優(yōu)質(zhì)、低耗于一身的先進(jìn)制造技術(shù)。相對(duì)于傳統(tǒng)的切削加工，其切削速度、進(jìn)給速度有了很大的提高，而且切削機(jī)理也不相同。高速切削使切削加工發(fā)生了本質(zhì)性的飛躍，其單位功率的金屬切除率提高了30%~40%，切削力降低了30%，刀具的切削壽命提高了70%，留于工件的切削熱大幅度降低，低階切削振動(dòng)幾乎消失。隨著切削速度的提高，單位時(shí)間毛坯材料的去除率增加了，切削時(shí)間減少了，加工效率提高了，從而縮短了產(chǎn)品的制造周期，提高了產(chǎn)品的市場(chǎng)競(jìng)爭(zhēng)力。同時(shí)，高速加工的小量快進(jìn)使切削力減少了，切屑的高速排出減少了工件的切削力和熱應(yīng)力變形，提高了剛性差和薄壁零件切削加工的可能性。由于切削力的降低，轉(zhuǎn)速的提高使切削系統(tǒng)的工作頻率遠(yuǎn)離機(jī)床的低階固有頻率，而工件的表面粗糙度對(duì)低階頻率最為敏感，由此降低了表面粗糙度。在模具的高淬硬鋼件(HRC45~HRC65)的加工過(guò)程中，采用高速切削可以取代電加工和磨削拋光的工序，從而避免了電極的制造和費(fèi)時(shí)的電加工，大幅度減少了鉗工的打磨與拋光量。對(duì)于一些市場(chǎng)上越來(lái)越需要的薄壁模具工件，高速銑削也可順利完成，而且在高速銑削CNC加工中心上，模具一次裝夾可完成多工步加工。高速加工技術(shù)對(duì)模具加工工藝產(chǎn)生了巨大影響，改變了傳統(tǒng)模具加工采用的“退火→銑削加工→熱處理→磨削”或“電火花加工→手工打磨、拋光”等復(fù)雜冗長(zhǎng)的工藝流程，甚至可用高速切削加工替代原來(lái)的全部工序。高速加工技術(shù)除可應(yīng)用于淬硬模具型腔的直接加工(尤其是半精加工和精加工)外，在EDM電極加工、快速樣件制造等方面也得到了廣泛應(yīng)用。大量生產(chǎn)實(shí)踐表明，應(yīng)用高速切削技術(shù)可節(jié)省模具后續(xù)加工中約80%的手工研磨時(shí)間，節(jié)約加工成本費(fèi)用近30%，模具表面加工精度可達(dá)1m，刀具切削效率可提高1倍。羊高速無(wú)銑削狂加工憲機(jī)床毀高速稿切削文技術(shù)員是切廣削加勉工技摧術(shù)的私主要餐發(fā)展?jié)较蚧笾惶?，它?yàn)隨景著院CN砍C謀技術(shù)萄、微牙電子伐技術(shù)項(xiàng)、新晚材料丈和新偏結(jié)構(gòu)眨等基板礎(chǔ)技撈術(shù)的務(wù)發(fā)展眨而邁鬼上更極高的旋臺(tái)階肆。由送于模聰具加盯工的胞特殊唉性以墓及高繳速加推工技柏術(shù)的虎自身惕特點(diǎn)動(dòng)，對(duì)排模具冶高速截加工漁的相逆關(guān)技剝術(shù)及猾工藝網(wǎng)系榆統(tǒng)湖(灣加歡工給機(jī)床搏、數(shù)睛控系秋統(tǒng)、較刀具移等攔)汽提出辟了虧比傳稻統(tǒng)模唱具加君工更覆高的孟要求亭。憶高穩(wěn)兆定性礎(chǔ)的機(jī)憐床支夕撐部忍件妄高速啦切削批機(jī)床著的床豪身等世支撐仰部件劣應(yīng)具椒有很浸好的蒸動(dòng)、撓靜剛霜度，滿熱剛斗度和奇最佳毛的選阻尼例特性夸。大葡部分抗機(jī)床丸都采些用高盾質(zhì)量叨、高悄剛性執(zhí)和高民抗張企性的帶灰鑄載鐵作慧為支壽撐部舌件材諒料，弱有的叼機(jī)床插公司家還在脾底座蝦中添泉加高蜓阻尼衡特性如的聚疊合物統(tǒng)混凝刷土，發(fā)以增梯加其辜抗振衰性和身熱穩(wěn)正定性析，這佩不但毀可保魯證機(jī)常床精豬度穩(wěn)霞定，倦也可燦防止棟切削慨時(shí)刀唐具振痰顫。研采用蝦封閉柿式床庸身設(shè)角計(jì)，乞整體刻鑄造屢床身盈，對(duì)股稱(chēng)床否身結(jié)擇構(gòu)并殖配有肥密布記的加毫強(qiáng)筋胡等也嫁是提泡高機(jī)校床穩(wěn)饑定性債的重因要措?yún)捠?。御一些僅機(jī)床調(diào)公司志的研勢(shì)發(fā)部丑門(mén)在興設(shè)計(jì)貢過(guò)程逆中，救還采橡用模洞態(tài)分隙析和豈有限職元結(jié)反構(gòu)編計(jì)算全等，醉優(yōu)化差了結(jié)習(xí)構(gòu)，瓶使機(jī)液床支凈撐部運(yùn)件更撕加穩(wěn)碼定可瓶靠。擔(dān)機(jī)床蓬主軸怎高速歷機(jī)床霧的主信軸性機(jī)能是鄰實(shí)現(xiàn)豆高速蓬切削會(huì)加工勝的重?cái)y要條獨(dú)件。體高速氧切削矮機(jī)床憶主軸框的轉(zhuǎn)朗速范桿圍漠為偉10渾00喉0~恩1宰00伯00貧0m深/m等i便n驗(yàn)，主性軸功妨率大乖于般15槽k士W應(yīng)。通加過(guò)主扯軸壓別縮空丙氣或俗冷卻銹系統(tǒng)賤控制養(yǎng)刀柄鋸和主算軸間哄的軸嬸向間認(rèn)隙不低大蒙于霞0.洋00矛5m凝m鑒。還辜要求呈主軸哈具有鑰快速敲升速課、在責(zé)指定臥位置岡快速師準(zhǔn)停洋的性暢能筒(疲即具穩(wěn)有極白高的簽角加菊減速涂度棋)冒，因拴此高侵速主碗軸常更采用漸液體偽靜壓警軸承密式、刺空氣獅靜壓份軸承雞式、傅熱壓釀氮化氣硅妖（成Si琴3N先4配）陶靠瓷軸遵承磁肺懸浮晴軸承略式等待結(jié)構(gòu)抗形式利。潤(rùn)秘滑多撥采用分油氣床潤(rùn)滑泛、噴掘射潤(rùn)聾滑等序技術(shù)確。主途軸冷梳卻一舒般采福用主遲軸內(nèi)寸部水首冷或苦氣冷擊。按機(jī)床堵驅(qū)動(dòng)會(huì)系統(tǒng)扒為滿趟足桶模具某高速壁加工腎的需蔑要，僵高速與加工錦機(jī)床蒸的驅(qū)臭動(dòng)系室統(tǒng)應(yīng)領(lǐng)具有趟下列驕特性桐：柔高的量進(jìn)給永速度己。普研究頌表明千，對(duì)圾于小被直徑校刀具嚇，提顯高轉(zhuǎn)播速和墻每齒惰進(jìn)通給量物有利如于降而低刀管具磨榨損。杜目前嗎常用爽的進(jìn)矩給速孤度范壩圍警為材20性~3微0m籌/m尺i星n稿，如蠟采用賠大導(dǎo)捧程滾汪珠絲鍵杠傳縮動(dòng)，級(jí)進(jìn)給追速度顛可煙達(dá)準(zhǔn)60去m/乒mi議n開(kāi)；采葉用直椅線電孝機(jī)則辮可使從進(jìn)給摟速度癢達(dá)華到壓12圣0m獨(dú)/m醋i擇n爺。稍高的典加速繭度。顧對(duì)三轟維復(fù)仇雜曲緒面廓彩形的克高速邁加工淋要求置驅(qū)動(dòng)燥系統(tǒng)滋具有廟良好繩的加那速度撥特性陳，要潮求提船供高簽速進(jìn)輛給的妖驅(qū)動(dòng)蛛器爆(轟快進(jìn)誕速度杰約臥40升m/斃m(xù)i索n霜，必3液D阿輪廓蓋加工桐速度逆為勻10兄m/朽mi紙n叨)情，能女夠提沃供龜0.臘4m槽/s蟲(chóng)2部到蜜10發(fā)m/裂s被2廉的加莖速度饅和減趕速度稅。日機(jī)床顏制造鴉商大越多采手用全闊閉環(huán)打位置獸伺服侄控制漿的小諷導(dǎo)程睬、大俗尺寸麥、高盡質(zhì)量拳的滾百珠絲注杠或趕大導(dǎo)氏程多氏頭絲儀杠。傍隨著繼電機(jī)敗技術(shù)蹈的發(fā)爛展，篇先進(jìn)饅的直潛線煎電動(dòng)語(yǔ)機(jī)已凍經(jīng)問(wèn)株世，坊并成私功應(yīng)秘用顧于級(jí)CN葵C移機(jī)床巡。先烘進(jìn)的附直線悄電動(dòng)租機(jī)驅(qū)尼動(dòng)漠使攝CN躍C瓣機(jī)床免不再叔有質(zhì)室量慣襖性、利超前扭、滯號(hào)后和呢振動(dòng)吳等問(wèn)特題，辜加快撤了伺夫服響慢應(yīng)速魂度，峽提高犧了伺寫(xiě)服控乏制精旺度和機(jī)機(jī)床域加工需精度唇。佛數(shù)控稿系統(tǒng)政先進(jìn)斧的數(shù)甩控系色統(tǒng)是哥保證盆模具袋復(fù)雜術(shù)曲面摩高速繳加工蜓質(zhì)量攔和效鑰率的喊關(guān)鍵銳因素出，模藍(lán)具高綁速切棍削加襪工對(duì)順數(shù)控倍系統(tǒng)歌的基攪本要歉求為葬：拖a.考高速廉的數(shù)魚(yú)字控祥制回臣路羞(D燭ig溫it吉al抓c騾on園tr醬ol勾l蝦oo虹p豪)工，包球括樹(shù)：禁3藏2磨位或鴨6扎4窗位并海行處唇理器飲及俊1.紐5G動(dòng)b港以上閘的硬插盤(pán)；退極短挑的直榴線電幅機(jī)采丈樣時(shí)撤間。悅b.掌仙速度柱和加檔速度航的前坦饋控失制煎(F建ee嘆d戶fo氧rw偏ar腿d挺co滑nt桐ro遮l燭)監(jiān)；數(shù)香字驅(qū)慕動(dòng)系驅(qū)統(tǒng)的炒爬行童控瘋制侍(J素er憑k尚co付nt鹿ro古l檔)遣。隸c.貫先進(jìn)鈴的插揉補(bǔ)方陸法興(提基衫于倍NU聞RB家S愿的樣塵條插圣補(bǔ)街)肝，以騰獲得粗良好飛的表時(shí)面質(zhì)劇量、貿(mào)精確廉的尺論寸和鬧高的射幾何言精度扇?？甦.躍恭預(yù)處肚理涼(L中oo綁k-浮ah搏ea魯d魚(yú))筍功能鹿。要樣求具御有大訴容量鄉(xiāng)緩沖愿寄存攀器，裕可預(yù)什先閱諷讀和遇檢查武多個(gè)畫(huà)程序把段誓(糕如代DM研G眠機(jī)床菠可多鑄達(dá)律50與0政個(gè)程奧序段描，寒Si達(dá)me蝴n蓬s磚系統(tǒng)職可憶達(dá)典10輕00株~2種00繳0涂個(gè)程于序現(xiàn)段申)爺，以謠便在嶼被加凈工表櫻面形嘩狀肌(亭曲餃率表)急發(fā)生指變化蹄時(shí)可歡及時(shí)創(chuàng)采取環(huán)改變這進(jìn)給陷速度需等措駁施以蜘避免扶過(guò)切午等。趣e.鏟宏誤差啦補(bǔ)償史功能保，包唉括因董直線加電機(jī)夾、主敬軸等啄發(fā)熱色導(dǎo)致謎的熱包誤差具補(bǔ)償緒、象拼限誤錘差補(bǔ)節(jié)償、俗測(cè)量漿系統(tǒng)超誤差遞補(bǔ)償
