三工位母線加工機在實現沖孔、切斷和折彎操作時，誤差難以避免。為了提高加工精度，對于誤差，采取盡量減小的措施。下面小編為大家介紹一下母線加工機誤差減小的方法：

1、三(san)(san)工(gong)(gong)位(wei)(wei)母線(xian)加(jia)工(gong)(gong)機(ji)重(zhong)復(fu)定(ding)位(wei)(wei)精(jing)度(du)的(de)影響(xiang)：母線(xian)加(jia)工(gong)(gong)機(ji)的(de)定(ding)位(wei)(wei)精(jing)度(du)是(shi)指(zhi)數(shu)控三(san)(san)工(gong)(gong)位(wei)(wei)母線(xian)加(jia)工(gong)(gong)機(ji)各(ge)坐標軸(zhou)在系統的(de)控制下(xia)運動的(de)位(wei)(wei)置(zhi)(zhi)精(jing)度(du)，引起(qi)定(ding)位(wei)(wei)誤差(cha)的(de)因素包(bao)括系統的(de)誤差(cha)和(he)(he)機(ji)械傳動的(de)誤差(cha)。而系統的(de)誤差(cha)則(ze)與插補誤差(cha)、跟蹤誤差(cha)等有關。三(san)(san)工(gong)(gong)位(wei)(wei)母線(xian)加(jia)工(gong)(gong)機(ji)機(ji)重(zhong)復(fu)定(ding)位(wei)(wei)精(jing)度(du)是(shi)指(zhi)重(zhong)復(fu)定(ding)位(wei)(wei)時(shi)坐標軸(zhou)的(de)實際位(wei)(wei)置(zhi)(zhi)和(he)(he)理想位(wei)(wei)置(zhi)(zhi)的(de)符合程(cheng)度(du)。

2、三工(gong)位母線(xian)加(jia)(jia)(jia)工(gong)機刀(dao)具誤差(cha)的影響：在加(jia)(jia)(jia)工(gong)中心上，由于(yu)采用(yong)的刀(dao)具具有自動交換(huan)功能，因而(er)在提高生(sheng)產率的同(tong)時，也帶來了刀(dao)具交換(huan)誤差(cha)。用(yong)同(tong)一把刀(dao)具加(jia)(jia)(jia)工(gong)一批工(gong)件時，由于(yu)頻繁重(zhong)(zhong)復換(huan)刀(dao)，致(zhi)使刀(dao)柄相對于(yu)主軸(zhou)錐孔產生(sheng)重(zhong)(zhong)復定位誤差(cha)而(er)降低加(jia)(jia)(jia)工(gong)精度。

3、三工(gong)(gong)(gong)位母線加工(gong)(gong)(gong)機檢測裝(zhuang)置(zhi)(zhi)的影響：檢測反(fan)(fan)饋(kui)裝(zhuang)置(zhi)(zhi)也稱為反(fan)(fan)饋(kui)元件(jian)，通(tong)常安裝(zhuang)在三工(gong)(gong)(gong)位母線加工(gong)(gong)(gong)機工(gong)(gong)(gong)作臺或絲(si)杠(gang)上，檢測反(fan)(fan)饋(kui)裝(zhuang)置(zhi)(zhi)將工(gong)(gong)(gong)作臺位移量轉換成電信號，并且反(fan)(fan)饋(kui)給數控(kong)(kong)裝(zhuang)置(zhi)(zhi)，如果與指令值比較有誤差，則控(kong)(kong)制工(gong)(gong)(gong)作臺向(xiang)消(xiao)除(chu)誤差的方向(xiang)移動。數控(kong)(kong)系(xi)(xi)統(tong)按有無檢測裝(zhuang)置(zhi)(zhi)可分為開環(huan)(huan)、閉環(huan)(huan)與半閉環(huan)(huan)系(xi)(xi)統(tong)。開環(huan)(huan)系(xi)(xi)統(tong)精度取(qu)決于步進電動機和絲(si)杠(gang)精度，閉環(huan)(huan)系(xi)(xi)統(tong)精度取(qu)決于檢測裝(zhuang)置(zhi)(zhi)精度。檢測裝(zhuang)置(zhi)(zhi)是高性能母線加工(gong)(gong)(gong)機的重(zhong)要組成部分。
