數控加工零件圖怎樣進行分析？

在數控工(gong)藝(yi)分(fen)析時，首先要(yao)對零件圖樣進行工(gong)藝(yi)分(fen)析，分(fen)析零件各(ge)加工(gong)部位的結構工(gong)藝(yi)性是否符合數控加工(gong)的特點，其主(zhu)要(yao)內容包括：

1、零件圖樣尺寸標(biao)注(zhu)(zhu)應符合編程的方(fang)便在數控(kong)加工圖上，宜采用以同一(yi)基準(zhun)(zhun)引(yin)注(zhu)(zhu)尺寸或直接給出坐標(biao)尺寸。這(zhe)種標(biao)注(zhu)(zhu)方(fang)法(fa)，既便于編程，也便于協調設計基準(zhun)(zhun)、工藝(yi)基準(zhun)(zhun)、檢測基準(zhun)(zhun)與(yu)編程零點的設置和計算。

2、零(ling)件(jian)(jian)輪(lun)廓結(jie)構的(de)幾何(he)元素條件(jian)(jian)應(ying)充分(fen)(fen)在編程(cheng)(cheng)時要(yao)對構成(cheng)零(ling)件(jian)(jian)輪(lun)廓的(de)所(suo)有(you)幾何(he)元素進(jin)行定義。在分(fen)(fen)析零(ling)件(jian)(jian)圖時，要(yao)分(fen)(fen)析各種幾何(he)元素的(de)條件(jian)(jian)是否(fou)充分(fen)(fen)，如(ru)果(guo)不充分(fen)(fen)，則無法對被(bei)加工的(de)零(ling)件(jian)(jian)進(jin)行編程(cheng)(cheng)或造型。

3、零(ling)件所(suo)要求的(de)加(jia)工(gong)精度(du)、尺寸(cun)公差應能否(fou)得(de)到保證雖(sui)然數控機(ji)床(chuang)加(jia)工(gong)精度(du)很高，但對一些特殊情況，例如薄(bo)(bo)壁零(ling)件的(de)加(jia)工(gong)，由于薄(bo)(bo)壁件的(de)剛性較差，加(jia)工(gong)時產生的(de)切削(xue)力及(ji)薄(bo)(bo)壁的(de)彈性退讓極易產生切削(xue)面的(de)振動，使(shi)得(de)薄(bo)(bo)壁厚度(du)尺寸(cun)公差難以保證，其表(biao)面粗糙(cao)度(du)也隨之增大，根(gen)據(ju)實踐經驗，對于面積較大的(de)薄(bo)(bo)壁，當其厚度(du)小于3mm時，應在工(gong)藝上充(chong)分重視這一問(wen)題。

4、零件(jian)(jian)內輪(lun)(lun)(lun)廓和(he)外形輪(lun)(lun)(lun)廓的幾何類(lei)(lei)型和(he)尺寸(cun)是否統一(yi)在(zai)數(shu)控編(bian)程，如(ru)果零件(jian)(jian)的內輪(lun)(lun)(lun)廓與外輪(lun)(lun)(lun)廓幾何類(lei)(lei)型相同或(huo)相似，考慮是否可以編(bian)在(zai)同一(yi)個程序，盡可能(neng)減少(shao)規(gui)格和(he)換刀次(ci)數(shu)，以減少(shao)輔助時(shi)間，提(ti)高加工效率。需要注意的是，的直徑常常受(shou)內輪(lun)(lun)(lun)廓圓弧(hu)半徑R限制。

5、零件的(de)工(gong)(gong)藝結構設計能否采用較大(da)直(zhi)徑(jing)的(de)進(jin)行(xing)加(jia)工(gong)(gong)采用較大(da)直(zhi)徑(jing)銑刀(dao)來加(jia)工(gong)(gong)，可以減少的(de)走刀(dao)次數，提高的(de)剛性(xing)系(xi)統，不但加(jia)工(gong)(gong)效率(lv)得(de)到(dao)提高，而且工(gong)(gong)件表面和底面的(de)加(jia)工(gong)(gong)質量(liang)也相應的(de)得(de)到(dao)提高。

6、零件銑(xian)(xian)(xian)(xian)(xian)削(xue)面(mian)(mian)的(de)(de)槽底(di)圓角半徑(jing)或底(di)板與緣(yuan)板相交處的(de)(de)圓角半徑(jing)r不宜(yi)太大(da)(da)(da)由于銑(xian)(xian)(xian)(xian)(xian)刀(dao)(dao)(dao)與銑(xian)(xian)(xian)(xian)(xian)削(xue)平面(mian)(mian)接觸(chu)的(de)(de)最大(da)(da)(da)直徑(jing)d=D-2r，其中D為銑(xian)(xian)(xian)(xian)(xian)刀(dao)(dao)(dao)直徑(jing)。當D一定時，圓角半徑(jing)r（如圖(tu)（1、所示、越(yue)(yue)(yue)大(da)(da)(da)，銑(xian)(xian)(xian)(xian)(xian)刀(dao)(dao)(dao)端刃(ren)銑(xian)(xian)(xian)(xian)(xian)削(xue)平面(mian)(mian)的(de)(de)能(neng)力越(yue)(yue)(yue)差(cha)，效(xiao)率也(ye)(ye)就越(yue)(yue)(yue)低(di)，工藝性也(ye)(ye)越(yue)(yue)(yue)差(cha)。。當r大(da)(da)(da)到一定程度時甚至(zhi)必須(xu)用球頭(tou)銑(xian)(xian)(xian)(xian)(xian)刀(dao)(dao)(dao)加(jia)工，這是(shi)應當避(bi)免的(de)(de)。當D越(yue)(yue)(yue)大(da)(da)(da)而r越(yue)(yue)(yue)小，銑(xian)(xian)(xian)(xian)(xian)刀(dao)(dao)(dao)端刃(ren)銑(xian)(xian)(xian)(xian)(xian)削(xue)平面(mian)(mian)的(de)(de)面(mian)(mian)積就越(yue)(yue)(yue)大(da)(da)(da)，加(jia)工平面(mian)(mian)的(de)(de)能(neng)力越(yue)(yue)(yue)強，銑(xian)(xian)(xian)(xian)(xian)削(xue)工藝性當然也(ye)(ye)越(yue)(yue)(yue)好。有時，銑(xian)(xian)(xian)(xian)(xian)削(xue)的(de)(de)底(di)面(mian)(mian)面(mian)(mian)積較大(da)(da)(da)，底(di)部圓弧(hu)r也(ye)(ye)較大(da)(da)(da)時，可(ke)以用兩把r不同的(de)(de)銑(xian)(xian)(xian)(xian)(xian)刀(dao)(dao)(dao)分兩次進行切削(xue)。

7、保(bao)證(zheng)基(ji)(ji)準(zhun)統一原(yuan)則若(ruo)零(ling)件(jian)(jian)在(zai)(zai)銑削完一面后再重新(xin)安裝銑削面的(de)另一面，由于基(ji)(ji)準(zhun)不統一，往(wang)往(wang)會因為零(ling)件(jian)(jian)重新(xin)安裝而接不好刀，加工(gong)(gong)結束(shu)后正反(fan)兩面上的(de)輪廓位置(zhi)及尺寸的(de)不協調。因此，盡量(liang)利用零(ling)件(jian)(jian)本身具(ju)有的(de)合適的(de)孔或以零(ling)件(jian)(jian)輪廓的(de)基(ji)(ji)準(zhun)邊或專門(men)設(she)置(zhi)工(gong)(gong)藝孔（如在(zai)(zai)毛坯上增(zeng)加工(gong)(gong)藝凸臺或在(zai)(zai)后續(xu)工(gong)(gong)序要去除余量(liang)上設(she)置(zhi)基(ji)(ji)準(zhun)孔、等(deng)作為定位基(ji)(ji)準(zhun)，保(bao)證(zheng)兩次裝夾加工(gong)(gong)后相對位置(zhi)的(de)準(zhun)確性。

8、考慮零(ling)件的(de)(de)(de)變形情(qing)況(kuang)當零(ling)件在數控(kong)銑削過(guo)程中有變形情(qing)況(kuang)時(shi)，不但影響零(ling)件的(de)(de)(de)加工(gong)質量，有時(shi)，還會出現(xian)蹦刀的(de)(de)(de)現(xian)象。這(zhe)時(shi)就應該考慮銑削的(de)(de)(de)加工(gong)工(gong)藝問題，盡可能把粗、精加工(gong)分開或采用(yong)對稱去余量的(de)(de)(de)方法。當然也(ye)可以(yi)采用(yong)熱處(chu)理的(de)(de)(de)方法來解決。

在數控工序圖上應該表達的內容有哪些？

數控加工工藝文件既是數控加工、產品驗收的依據，也是操必須遵守、執行的規程。 它是編程人員在編制加工程序單時必須編制的技術文件。數控加工工藝文件要比普通機床加工的工藝文件復雜，它不但是零件數控加工的依據，也是必不可少的工藝資料檔案。

1.編程(cheng)任務(wu)書(shu) 用來闡明(ming)工(gong)藝(yi)人員對(dui)數(shu)控(kong)(kong)加工(gong)工(gong)序(xu)(xu)的技術要求、工(gong)序(xu)(xu)說明(ming)、數(shu)控(kong)(kong)加工(gong)前應該留有(you)的加工(gong)余量。是編程(cheng)員與(yu)工(gong)藝(yi)人員協調(diao)工(gong)作和編制數(shu)控(kong)(kong)加工(gong)程(cheng)序(xu)(xu)的重要依據(ju)之一。

2.數(shu)(shu)控(kong)加工(gong)工(gong)件(jian)安裝和(he)(he)零(ling)點設定卡 此表卡的(de)作(zuo)用(yong)，在于(yu)表達數(shu)(shu)控(kong)加工(gong)零(ling)件(jian)的(de)定位(wei)(wei)方式(shi)和(he)(he)夾(jia)緊(jin)方法(fa)，并應標明被加工(gong)零(ling)件(jian)的(de)零(ling)點設置位(wei)(wei)置和(he)(he)坐(zuo)標方向(xiang)，以及使(shi)用(yong)的(de)夾(jia)具名(ming)稱、編號等。

3.數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)卡(ka)(ka)(ka) 數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)卡(ka)(ka)(ka)與(yu)普通加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)卡(ka)(ka)(ka)相似之處是由(you)編程(cheng)員(yuan)根(gen)據被加(jia)工(gong)(gong)(gong)(gong)(gong)零(ling)件，編制數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)的工(gong)(gong)(gong)(gong)(gong)藝(yi)和作業(ye)內容；與(yu)普通加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)卡(ka)(ka)(ka)不(bu)同的是，此(ci)卡(ka)(ka)(ka)中還應該反映使(shi)用(yong)的輔(fu)具、切削參數(shu)(shu)、切削液等(deng)。它是操(cao)作人(ren)員(yuan)用(yong)數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)程(cheng)序(xu)(xu)進行數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)的主要指導性工(gong)(gong)(gong)(gong)(gong)藝(yi)資料。工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)卡(ka)(ka)(ka)應該按照已經確(que)定的工(gong)(gong)(gong)(gong)(gong)步順序(xu)(xu)填(tian)寫。數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)卡(ka)(ka)(ka)如下(xia)表所示。被加(jia)工(gong)(gong)(gong)(gong)(gong)零(ling)件的工(gong)(gong)(gong)(gong)(gong)步較少(shao)或(huo)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)加(jia)工(gong)(gong)(gong)(gong)(gong)內容較簡單(dan)時，此(ci)工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)卡(ka)(ka)(ka)也可以(yi)省略。但此(ci)時應該將工(gong)(gong)(gong)(gong)(gong)序(xu)(xu)加(jia)工(gong)(gong)(gong)(gong)(gong)內容填(tian)寫在數(shu)(shu)控(kong)(kong)(kong)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)件安裝和零(ling)點設定卡(ka)(ka)(ka)上(shang)。

4.數控加工卡 數控加工時對的要求十分嚴格。數控加工卡上要反映編號、結構、刀桿型號、刀片型號及材料或牌號等。它是組裝數控加工和調整數控加工的依據。數控加工卡如下表所示。在數控車床、數控銑床上進行加工時，由于使用的不多，此卡可以省略。但應該給出參與加工的各把相距被加工零件加工部位的坐(zuo)標(biao)(biao)尺(chi)寸，即換(huan)刀點相距(ju)被加工(gong)(gong)零件(jian)加工(gong)(gong)部位的坐(zuo)標(biao)(biao)尺(chi)寸。也可(ke)以在(zai)機床運(yun)行軌跡圖上，標(biao)(biao)注出各(ge)把(ba)在(zai)換(huan)刀時，相距(ju)被加工(gong)(gong)零件(jian)加工(gong)(gong)部位的坐(zuo)標(biao)(biao)尺(chi)寸。

5.數(shu)控(kong)機(ji)床(chuang)調(diao)(diao)(diao)整(zheng)卡(ka)(ka)(ka) 數(shu)控(kong)機(ji)床(chuang)調(diao)(diao)(diao)整(zheng)卡(ka)(ka)(ka)是機(ji)床(chuang)操作人員在數(shu)控(kong)加工(gong)前調(diao)(diao)(diao)整(zheng)機(ji)床(chuang)的(de)(de)依(yi)據(ju)。主要(yao)包括機(ji)床(chuang)控(kong)制面(mian)板(ban)開(kai)關(guan)調(diao)(diao)(diao)整(zheng)單(dan)和(he)數(shu)控(kong)加工(gong)零(ling)件安裝與(yu)零(ling)點(dian)設定(ding)(ding)卡(ka)(ka)(ka)兩部分。機(ji)床(chuang)控(kong)制面(mian)板(ban)開(kai)關(guan)調(diao)(diao)(diao)整(zheng)單(dan)主要(yao)記有(you)機(ji)床(chuang)控(kong)制面(mian)板(ban)上(shang)有(you)關(guan)“開(kai)關(guan)”的(de)(de)位置(zhi)(zhi)(zhi)，例如(ru)進給速度F、調(diao)(diao)(diao)整(zheng)旋扭位置(zhi)(zhi)(zhi)或(huo)超調(diao)(diao)(diao)（倍率(lv)）旋扭位置(zhi)(zhi)(zhi)，半(ban)徑補償(chang)旋扭位置(zhi)(zhi)(zhi)或(huo)補償(chang)撥碼(ma)開(kai)關(guan)組數(shu)值(zhi)表、垂直(zhi)校驗開(kai)關(guan)及冷卻方式等內(nei)容。數(shu)控(kong)機(ji)床(chuang)調(diao)(diao)(diao)整(zheng)卡(ka)(ka)(ka)的(de)(de)格式如(ru)下表所(suo)示。數(shu)控(kong)銑床(chuang)上(shang)加工(gong)時，此卡(ka)(ka)(ka)可以簡化，也可以省略。但必須將上(shang)述內(nei)容要(yao)求填(tian)寫在數(shu)控(kong)加工(gong)工(gong)件安裝和(he)零(ling)點(dian)設定(ding)(ding)卡(ka)(ka)(ka)上(shang)。

7.數(shu)(shu)控(kong)(kong)加(jia)(jia)工(gong)程(cheng)(cheng)序(xu)單 數(shu)(shu)控(kong)(kong)加(jia)(jia)工(gong)程(cheng)(cheng)序(xu)單，是(shi)編程(cheng)(cheng)員根據(ju)工(gong)藝(yi)分析情況，經過(guo)數(shu)(shu)值計算，按(an)照數(shu)(shu)控(kong)(kong)機床規定的指令代(dai)碼，根據(ju)運(yun)行軌(gui)跡圖的數(shu)(shu)據(ju)處(chu)理而(er)進行編寫的。它是(shi)記錄(lu)數(shu)(shu)控(kong)(kong)加(jia)(jia)工(gong)工(gong)藝(yi)過(guo)程(cheng)(cheng)、工(gong)藝(yi)參數(shu)(shu)、位移數(shu)(shu)據(ju)等(deng)的綜合清單，用來實現(xian)數(shu)(shu)控(kong)(kong)加(jia)(jia)工(gong)。它的格式隨數(shu)(shu)控(kong)(kong)系統和機床種類(lei)的不同而(er)有(you)所差異(yi)。

用一個數控編程連續加工多個同樣的產品編程該怎么編？

如果(guo)需要(yao)使用數(shu)控機床連(lian)續(xu)加(jia)工(gong)多(duo)個(ge)同(tong)樣的產品，可以通過"重復循環"或(huo)者"子程序"的方(fang)式(shi)進行編程。以下是兩(liang)種方(fang)式(shi)的具體(ti)介紹：

1. 重(zhong)復(fu)循(xun)環編(bian)程(cheng)方(fang)法: 可以(yi)使(shi)用G73/G83等(deng)循(xun)環加(jia)工(gong)指令，在數控編(bian)程(cheng)語言中(zhong)，通過多(duo)次重(zhong)復(fu)執行某個程(cheng)序段的(de)方(fang)式，完成同(tong)樣(yang)的(de)加(jia)工(gong)操作。一(yi)般情況下，循(xun)環加(jia)工(gong)指令指定了循(xun)環次數，并根(gen)據(ju)加(jia)工(gong)要(yao)求給出(chu)程(cheng)序段的(de)起始(shi)和終止點(dian)，加(jia)工(gong)程(cheng)序段中(zhong)的(de)相關指令會重(zhong)復(fu)執行多(duo)次，直到循(xun)環次數滿足為止。

2. 子(zi)程(cheng)(cheng)序(xu)(xu)(xu)編程(cheng)(cheng)方法: 子(zi)程(cheng)(cheng)序(xu)(xu)(xu)是(shi)一(yi)段獨(du)立的(de)程(cheng)(cheng)序(xu)(xu)(xu)代(dai)碼，可(ke)(ke)以通(tong)過G65指(zhi)令進行調用(yong)(yong)。在使用(yong)(yong)子(zi)程(cheng)(cheng)序(xu)(xu)(xu)編程(cheng)(cheng)之前(qian)，需要預先(xian)定(ding)義(yi)(yi)好子(zi)程(cheng)(cheng)序(xu)(xu)(xu)中要執行的(de)指(zhi)令序(xu)(xu)(xu)列及相(xiang)關參數，最(zui)后通(tong)過 G65 指(zhi)令調用(yong)(yong)即可(ke)(ke)。子(zi)程(cheng)(cheng)序(xu)(xu)(xu)的(de)定(ding)義(yi)(yi)一(yi)般使用(yong)(yong)O、M等指(zhi)令完(wan)(wan)成(cheng)，如O100，代(dai)表子(zi)程(cheng)(cheng)序(xu)(xu)(xu)號為100。在主程(cheng)(cheng)序(xu)(xu)(xu)中調用(yong)(yong)子(zi)程(cheng)(cheng)序(xu)(xu)(xu)時使用(yong)(yong) G65 P100 即可(ke)(ke)調用(yong)(yong)子(zi)程(cheng)(cheng)序(xu)(xu)(xu)100，從而完(wan)(wan)成(cheng)一(yi)定(ding)的(de)加工操作。

需要注意的(de)是，無論使用哪(na)種方(fang)式(shi)編程(cheng)，都需要在主程(cheng)序(xu)中設置初始的(de)加工(gong)坐標，然后根據(ju)加工(gong)要求(qiu)設定適當(dang)的(de)工(gong)件坐標系、半徑(jing)補償、切(qie)削參數等，確保(bao)加工(gong)的(de)一(yi)致性和穩(wen)定性。

數控機床主要用于加工哪些零件？

數控機(ji)床最(zui)適宜加工以下類型的零件：　　

1.多品種中小批量零件(jian)。隨著(zhu)數控機床制造成本的(de)逐步下降，現(xian)在不管是國(guo)內(nei)還是國(guo)外，加工(gong)大批量零件(jian)的(de)情況也已經出現(xian)。加工(gong)很小批量和單件(jian)生產時，如能(neng)縮短程序的(de)調(diao)試時間(jian)和工(gong)裝的(de)準備時間(jian)也是可以(yi)選(xuan)用的(de)。

2.精(jing)(jing)(jing)度要求(qiu)高(gao)的(de)零(ling)件。有于數(shu)控機床的(de)剛性好，制造精(jing)(jing)(jing)度高(gao)，對刀精(jing)(jing)(jing)確(que)，能(neng)方便的(de)進行尺寸(cun)補償，所以能(neng)加工尺寸(cun)精(jing)(jing)(jing)度要求(qiu)高(gao)的(de)零(ling)件。　　

3.表(biao)面粗(cu)(cu)糙(cao)(cao)度(du)(du)值(zhi)(zhi)小的(de)(de)(de)(de)零件。在(zai)工(gong)(gong)件和(he)的(de)(de)(de)(de)材料、精加工(gong)(gong)余量及角度(du)(du)一定的(de)(de)(de)(de)情(qing)況下，表(biao)面粗(cu)(cu)糙(cao)(cao)度(du)(du)取決(jue)于切削速(su)(su)度(du)(du)和(he)進給速(su)(su)度(du)(du)。普通(tong)機床(chuang)是(shi)恒定轉速(su)(su)，直徑不(bu)(bu)同(tong)(tong)切削速(su)(su)度(du)(du)就不(bu)(bu)同(tong)(tong)，像數控(kong)車床(chuang)具有(you)恒線速(su)(su)切削功能，車端面、鱷魚剪不(bu)(bu)同(tong)(tong)直徑外圓時(shi)可以用(yong)相同(tong)(tong)的(de)(de)(de)(de)線速(su)(su)度(du)(du)，保(bao)證表(biao)面粗(cu)(cu)糙(cao)(cao)度(du)(du)值(zhi)(zhi)既小且一致。在(zai)加工(gong)(gong)表(biao)面粗(cu)(cu)糙(cao)(cao)度(du)(du)不(bu)(bu)同(tong)(tong)的(de)(de)(de)(de)表(biao)面時(shi)，粗(cu)(cu)糙(cao)(cao)度(du)(du)小的(de)(de)(de)(de)表(biao)面選用(yong)小的(de)(de)(de)(de)進給速(su)(su)度(du)(du)，粗(cu)(cu)糙(cao)(cao)度(du)(du)大的(de)(de)(de)(de)表(biao)面選用(yong)大些(xie)的(de)(de)(de)(de)進給速(su)(su)度(du)(du)，可變性很好，這點在(zai)普通(tong)機床(chuang)很難做到(dao)。

4.輪(lun)廓形狀復雜的(de)零(ling)(ling)件。任(ren)意(yi)平(ping)面(mian)曲(qu)線(xian)都可以(yi)用直線(xian)或(huo)圓弧(hu)來逼近(jin)，數(shu)控機床具有圓弧(hu)插補功能，可以(yi)加工各(ge)種(zhong)復雜輪(lun)廓的(de)零(ling)(ling)件。　　

5.價值昂貴的零件，這種零件雖然生產量不大，但是如果加工中因出現差錯而報廢，將產生巨大的經濟損失。　　提高金屬加工行業技術，可(ke)以找一(yi)些平臺(tai)來(lai)多看(kan)多學，比(bi)如(ru)鑫機緣，或者在應用市(shi)場嘗試搜索一(yi)些金(jin)屬加工相關的應用~望(wang)采納。

數控車床加工零件時機床抖動（高轉速時和偏心加工時尤為明顯）且切加工面有震紋？

盤類(lei)零件：粗車(che)時往往不(bu)(bu)會出現(xian)振(zhen)文(wen)，只(zhi)在半(ban)精(jing)車(che)、精(jing)車(che)時出現(xian)，原理上市共振(zhen)引起，消除的(de)話須選(xuan)擇鋒利的(de)刀尖，主(zhu)軸轉速不(bu)(bu)能(neng)高(gao)，進給速度也(ye)不(bu)(bu)能(neng)高(gao)。當然(ran)，要是有辦法裝夾的(de)更緊、更可靠，一(yi)般不(bu)(bu)會出現(xian)振(zhen)文(wen)。

細長零件：同理，需要鋒利，刀尖與零件接觸面一定要小，低轉速、慢進給。能有跟刀架更好。

數控圖紙入門基礎知識？

需要先學(xue)習畫法(fa)幾何基(ji)礎，了(le)解(jie)點，線，面(mian)的(de)(de)基(ji)本作圖(tu)方法(fa)，然后再學(xue)習機械制(zhi)圖(tu)，掌握各種零件圖(tu)的(de)(de)畫法(fa)以及剖面(mian)圖(tu)，裝配圖(tu)的(de)(de)畫法(fa)，并初(chu)步能夠讀識零件圖(tu)。

最后用軟件繪圖并轉為數控加(jia)工語(yu)言進(jin)行(xing)編程，可(ke)以學習(xi)一(yi)些(xie)制圖的基礎課(ke)程，了解數控圖紙的要求。
