3、高，而且經(jīng)濟(jì)實(shí)惠。因?yàn)槲覀兯佑|機(jī)械設(shè)備很少，再加上操作難度關(guān)系我選擇華中世紀(jì)新數(shù)控系統(tǒng)，這樣方便我們編程和操作。再次是對(duì)課題的研究畫(huà)出二維圖，三維圖以確定毛坯尺寸，毛坯材料，材料的性質(zhì)，加工工藝，加工工序，編制加工程序，確定重點(diǎn)，難點(diǎn)及可能遇到的問(wèn)題。通過(guò)對(duì)這些的了解我們就能很好對(duì)所學(xué)知識(shí)的鞏固。2.工藝設(shè)計(jì) 零件分析2.1分析零件畫(huà)圖1.首先我們拿到課題后仔細(xì)的看一遍，對(duì)要加工的零件有個(gè)大概的了解，確定繪制的難點(diǎn)，特別是圓弧輪廓，對(duì)尺寸也要熟記，還有就是有特殊加工精度的地方也要記得為方便以后的加工工藝做好準(zhǔn)備，再就是對(duì)有公差地方也要注意，這對(duì)以后編制程序的時(shí)候主軸的轉(zhuǎn)速，進(jìn)給量是有幫助的。

4、做好這些工作之后，我們就開(kāi)始繪制二維圖，我們選用的軟件就是我們常用的CAD這個(gè)對(duì)我們來(lái)說(shuō)太熟悉了，用起來(lái)也方便。如果你覺(jué)得其他的好用你也可以選。我們選用的Mastercam,你也可以選其他的三維制圖軟件CAD、UGPorE等。2.再對(duì)繪制好的零件圖進(jìn)行審核，確定無(wú)誤后打印。3確定毛坯及材料3.1確定材料我們選用適合制造軸承的45#鋼。3.2確定毛坯毛坯尺寸我們選用160mmx120mmx40mm長(zhǎng)方體鍛件4工藝路線的設(shè)計(jì)1.我們先加工平面，外圓輪廓，粗銑平面銑，銑鍵槽，銑 100半圓，銑24x135.5槽，銑兩側(cè)臺(tái)階，鉆 30通孔，鉆16通孔。精銑各平面去銳邊倒角，去毛刺粗加工的被吃刀量為3m

5、m，主軸的轉(zhuǎn)速是800轉(zhuǎn)|分，進(jìn)給量為200mm|min。精加工x軸方向的加工余量為0.2mm，y軸的精加工余量為0.05mm，主軸的轉(zhuǎn)速1500轉(zhuǎn)|分,進(jìn)給量為80mm|min。鉆孔的轉(zhuǎn)速500轉(zhuǎn)|分。粗加工的刀具是主偏角為90度的外圓銑刀，精加工的刀具為35度菱形銑刀。5加工階段，工序的劃分4.1共分為7個(gè)階段。共分為八次工序。6夾具的選擇1.通用的夾具。在銑床上用來(lái)裝夾工件的裝置稱(chēng)為銑床夾具數(shù)控銑床的夾具與苷通銑床的夾具相同，銑床夾具可分為通用夾具和專(zhuān)用夾具兩大類(lèi)。通用夾具是指能夠裝夾兩種或兩種以上工件的同一類(lèi)夾具，例如：平口鉗又名機(jī)用虎鉗，是一種通用夾具，常用于安裝小型工件。它是銑床、

6、鉆床的隨機(jī)附件。將其固定在機(jī)床工作臺(tái)上，用來(lái)夾持工件進(jìn)行切削加工，專(zhuān)用夾具是專(zhuān)門(mén)為加丁某一指定千件的某一下序而設(shè)計(jì)的夾具。2.平口鉗（數(shù)控銑床自帶夾具）。如下圖7粗精基準(zhǔn)的選擇7.1粗基準(zhǔn)的選擇1.選擇重要表面為粗基準(zhǔn) 為保證工件上重要表面的加工余量小而均勻，則應(yīng)選擇該表面為粗基準(zhǔn)。2.選擇不加工表面為粗基準(zhǔn) 為了保證加工面與不加工面間的位置要求，一般應(yīng)選擇不加工面為粗基準(zhǔn)。3.選擇加工余量最小的表面為粗基準(zhǔn)。4.選擇較為平整光潔、加工面積較大的表面為粗基準(zhǔn) 以便工件定位可靠、夾緊方便。5) 粗基準(zhǔn)在同一尺寸方向上只能使用一次選作粗基準(zhǔn)。7.2精基準(zhǔn)的選擇1) 基準(zhǔn)重合原則。2) 基準(zhǔn)統(tǒng)一原則

7、。3) 自為基準(zhǔn)原則。4) 互為基準(zhǔn)原則。5) 便于裝夾原則。自為基準(zhǔn)原則某些要求加工余量小而均勻的精加工工序選擇加工面進(jìn)行加工時(shí)需要兩個(gè)表面互相作為基準(zhǔn)反復(fù)進(jìn)行加工以保證位置精度要求，應(yīng)選中心孔為精基準(zhǔn)。7.3 量具的選擇常用的有游標(biāo)卡尺，千分尺。游標(biāo)卡尺是測(cè)量長(zhǎng)度、寬度、內(nèi)經(jīng)等等。其用途與千分尺差不多，但精確度要高些。而且右邊卡尺不便于測(cè)量該圖，根據(jù)圖紙的要求我們選擇游標(biāo)卡尺。8切削用量的確定合理選擇切削用量的原則是，粗加工時(shí)，一般以提高生產(chǎn)率為主，但也應(yīng)考慮經(jīng)濟(jì)性和加工成本；半精加工和精加工時(shí)，應(yīng)在保證加工質(zhì)量的前提下，兼顧切削效率、經(jīng)濟(jì)性和加工成本。具體數(shù)值應(yīng)根據(jù)機(jī)床說(shuō)明書(shū)、切削用量手

8、冊(cè)，并結(jié)合經(jīng)驗(yàn)而定。 8.1加工條件工件材料：45#鋼調(diào)質(zhì)處理 硬度220-240HB，取220。加工要求：鉆20，鏜30,34孔。機(jī)床：數(shù)控系統(tǒng)HNC-21M銑床。8.2粗銑外圓選擇刀具1，精銑外圓選擇刀具28.3確定切削深度粗銑外圓，一次走刀，則ap=1mm。8.4確定進(jìn)給量由切削用量手冊(cè)，HT200，刀桿尺160x25,工件最小直徑為24mm，則f=0.2-0.3mm/r。再由簡(jiǎn)明手冊(cè)表4.2-3查取f =0.22mm/r。8.5確定切削速度VC根據(jù)切削用量手冊(cè)表1.27查?。?96 r/min取900。8.6鉆30孔 8.7刀具選擇查機(jī)械制造工藝設(shè)計(jì)簡(jiǎn)明手冊(cè)選用15高速鋼錐柄標(biāo)準(zhǔn)花鉆。

9、8.8切削用量選擇：查切削用量手冊(cè)得：f=0.70-0.86mm/r,再由機(jī)械制造工藝設(shè)計(jì)簡(jiǎn)明手冊(cè)CK6140銑床進(jìn)給量取f =0.76mm/r。查切削用量簡(jiǎn)明手冊(cè)取V=400r/min。確定切削深度，一次走刀，則ap=1mm。8.9銑12x17槽（1）確定切削深度，一次走刀，則ap=1mm。（2)確定進(jìn)給量由切削用量手冊(cè)表1.4，f=0.6-0.9mm/r。根據(jù)XA6140機(jī)床說(shuō)明書(shū)（見(jiàn)工藝手冊(cè)表1.31）取f=0.86 mm/r。（3)確定切削速度VC根據(jù)切削用量手冊(cè)表1.27查取：346.815 r/min。按XK6140銑床說(shuō)明書(shū)，選擇與36.815r/min相近似的機(jī)床轉(zhuǎn)速n =35

10、0r/min,則實(shí)際切削速度。5)34,30孔的鏜孔速度取120m/min,f=0.05mm/r9刀具的選擇刀具選擇要考慮許多問(wèn)題，相應(yīng)地就有許多原則，如效率原則、加工精度原則、穩(wěn)定性原則、經(jīng)濟(jì)性原則等等刀具的合理選擇和使用在生產(chǎn)加工占據(jù)及其重要的作用。刀具的種類(lèi)很多，就其材料而言，就有高速鋼、硬質(zhì)合金、陶瓷等。根據(jù)零件的材料不同，我們所選的刀具也不同，比如數(shù)控銑削的零件一般采用硬質(zhì)合金，數(shù)控銑床一般采用高速鋼。刀具的選擇是在數(shù)控編程的人機(jī)交互狀態(tài)下進(jìn)行的。應(yīng)根據(jù)機(jī)床的加工能力、工件材料的性能、加工工序、切削用量以及其它相關(guān)因素正確選用刀具及刀柄。刀具選擇總的原則是：安裝調(diào)整方便，剛性好，耐用

11、度和精度高。在滿足加工要求的前提下，盡量選擇較短的刀柄，以提高刀具加工的剛性。（具體情況參見(jiàn)附錄刀具卡片）10工序內(nèi)容擬定1機(jī)床的選定我選擇的是華中世際星數(shù)控系統(tǒng)。2手工編程O(píng)0801%0801G17G90G40G49G21G54M06T04 換上平面銑刀M03S800F600 （設(shè)置粗銑轉(zhuǎn)速 進(jìn)給速度 ）M08G00X0Y0Z3 銑平面銑平面 G01Z-5X160Y40X0Y80X160Z-10X0Y40X160Y0X0G00Z100M06T01G00G41X0Y120Z5G01Z-5X70Z-10X0G01X52Y120 銑12x17槽Z-10V-11G03X64Y109R-6G01Y12
