如何減(jian)少立式(shì)加工中(zhong)心加工(gōng)工件的(de)誤差

2025-12-26

　　任(rèn)何加工(gōng)設備，在(zai)工件加(jiā)工時如(ru)加工路(lu)線設置(zhì)、加工程(cheng)序編制(zhi)、加工刀(dao)具選擇(ze)、機床自(zi)身問題(ti)、裝夾問(wèn)題及工(gōng)件材質(zhì)等有問(wèn)題時，對(dui)工件的(de)加工精(jing)度和加(jia)工效☀️率(lǜ)都會造(zào)成影響(xiang)，立式加(jiā)工中心(xīn)作爲高(gao)精的加(jiā)工設備(bei)，減少工(gong)件加工(gōng)誤差常(chang)用的方(fāng)法主要(yào)有減少(shǎo)原始誤(wu)差法、誤(wù)差補償(cháng)法、誤差(cha)轉移法(fa)、誤差🐆分(fèn)組法、誤(wù)差💃平均(jun1)法及誤(wu)差合成(cheng)法等。

　　一(yī)、誤差合(he)成法

　　減(jian)少機床(chuáng)自身的(de)誤差是(shì)保證工(gōng)件加工(gōng)精度主(zhǔ)要的方(fang)法。誤差(chà)合成法(fǎ)，要求測(ce)量出機(jī)床各軸(zhóu)的各項(xiang)原始誤(wù)差。激光(guāng)幹涉儀(yi)因具有(you)測量精(jīng)度高、使(shi)用靈活(huo)等特點(diǎn)，是現在(zài)立式加(jiā)工中心(xin)主要的(de)檢測儀(yí)器。

　　二、誤(wù)差補償(cháng)法

　　誤差(cha)補償法(fǎ)是人爲(wei)地制造(zao)一種誤(wù)差，去抵(di)消工藝(yì)♌系‼️統固(gù)有的原(yuán)始誤差(cha)，或者利(li)用一種(zhǒng)原始誤(wu)差去抵(di)消另一(yī)📱種原🛀始(shǐ)誤差，從(cong)而達到(dao)提高立(li)式加工(gōng)中🐪心工(gōng)件☔加工(gōng)精度的(de)目的。通(tong)常通過(guò)減🏃小機(jī)床間隙(xi)，提高機(jī)床剛度(du) ，采用預(yu)加載荷(he)，使有關(guan)配合産(chan)生預🌂緊(jin)力，而減(jiǎn)少🍓間隙(xì)影響。還(hai)可以提(ti)高工件(jian)和刀具(ju)的剛度(du)減小刀(dāo)🈲具、工件(jian)的懸伸(shēn)長🚶‍♀️度，以(yǐ)提高工(gong)藝㊙️系統(tong)的剛度(dù)。還可以(yi)采用合(hé)理的裝(zhuang)夾方式(shì)和加工(gōng)方式，減(jian)⭕小切削(xuē)力及其(qí)變化，合(he)理地選(xuan)擇刀具(jù)材料，增(zeng)大前角(jiǎo)和主偏(piān)角，以及(jí)對工件(jiàn)材料進(jin)行合理(li)的熱處(chù)理以材(cái)料地加(jiā)工性能(neng)等幾種(zhǒng)方法。

　　三(san)、直接減(jian)少原始(shi)誤差法(fa)

　　直接減(jiǎn)少原始(shi)誤差法(fǎ)是指在(zai)查明影(yǐng)響加工(gong)精度的(de)主❌要✨原(yuán)始☁️誤差(cha)因素之(zhī)後，設法(fa)對其直(zhí)接進行(hang)減少或(huo)減少☀️。比(bi)如立式(shì)加工中(zhōng)心在長(zhǎng)時間使(shǐ)用後，由(you)📞于自然(ran)磨損造(zao)成的傳(chuán)動系統(tǒng)定位失(shī)準、反向(xiàng)間隙✍️等(deng)。

　　四、誤差(chà)平均法(fa)

　　五、誤(wu)差轉移(yi)法

　　誤差(chà)轉移法(fa)的實質(zhi)是轉移(yí)工藝系(xi)統的集(ji)合誤差(cha)、受力變(biàn)㊙️形及熱(rè)變形等(děng)引起的(de)綜合誤(wù)差。如立(lì)式加工(gōng)中心進(jìn)行一些(xiē)孔類加(jia)工，工件(jian)的同軸(zhóu)度不是(shi)靠機床(chuáng)主軸回(huí)轉精度(du)來保證(zhèng)的📱，而是(shi)靠夾具(jù)保證，當(dāng)機床主(zhǔ)軸與工(gōng)件采用(yong)浮動連(lián)接以後(hou)，機床主(zhǔ)軸的🈲原(yuan)始誤差(cha)就不再(zai)影響加(jia)工精度(du)，而轉移(yi)到夾具(jù)來🌂保證(zheng)加工精(jīng)度。

　　六、誤(wu)差分組(zǔ)法

　　在立(lì)式加工(gōng)中心加(jia)工中，由(yóu)于工序(xù)毛坯誤(wù)差的存(cún)❗在，造成(chéng)了本工(gōng)序的加(jiā)工誤差(chà)。毛坯誤(wu)差的變(biàn)化，對本(ben)工序的(de)影響💞主(zhǔ)要有兩(liang)種情況(kuang)：反應誤(wu)差和定(ding)位誤差(cha)。如果上(shang)述誤差(cha)太大，不(bu)能🙇🏻保證(zheng)加工精(jing)度，而且(qie)🔱要提高(gao)毛坯精(jīng)度或上(shàng)一道工(gōng)序加工(gōng)精度是(shi)不太現(xiàn)實的。

　　這(zhè)時可采(cai)用誤差(cha)分組法(fǎ)，即把毛(mao)坯或上(shang)工序尺(chi)寸按🧑🏾‍🤝‍🧑🏼誤(wu)差💃🏻大小(xiǎo)✨分爲n組(zu)，每組毛(máo)坯的誤(wu)差就縮(suo)小爲原(yuan)來的1/n，然(rán)後🏒按各(ge)組分别(bié)調整刀(dāo)具與工(gong)件的相(xiàng)對位置(zhi)或調整(zhěng)定位元(yuán)件，這樣(yàng)就可👨‍❤️‍👨大(da)大地縮(suo)小整批(pī)工件的(de)尺寸分(fèn)散範圍(wei)。誤差分(fèn)組法的(de)實質是(shì)用提高(gao)測量精(jīng)度的手(shǒu)段來彌(mí)補加工(gong)精度的(de)不足,從(cóng)而達到(dao)減少加(jia)工誤差(cha)的影響(xiang)。
