由于cnc加(jia)(jia)工(gong)(gong)(gong)中心其是(shi)采用軟(ruan)件完成(cheng)鎖(suo)(suo)定的，在仿(fang)真(zhen)模擬(ni)(ni)生(sheng)產加(jia)(jia)工(gong)(gong)(gong)時，當按著自(zi)啟按鍵時在仿(fang)真(zhen)模擬(ni)(ni)頁(ye)面(mian)并沒(mei)法直接地看到cnc加(jia)(jia)工(gong)(gong)(gong)是(shi)否已鎖(suo)(suo)定。仿(fang)真(zhen)模擬(ni)(ni)時常常又沒(mei)有(you)對刀(dao)，如(ru)果cnc加(jia)(jia)工(gong)(gong)(gong)中心也沒(mei)有(you)鎖(suo)(suo)住運(yun)行，很容易再(zai)次出現撞刀(dao)。所以在仿(fang)真(zhen)模擬(ni)(ni)精加(jia)(jia)工(gong)(gong)(gong)前需(xu)到運(yun)行操作面(mian)板核對一下cnc加(jia)(jia)工(gong)(gong)(gong)中心是(shi)否鎖(suo)(suo)住。精加(jia)(jia)工(gong)(gong)(gong)時忘記關閉空(kong)(kong)運(yun)作開(kai)關。畢竟在程序仿(fang)真(zhen)模擬(ni)(ni)時，便于合理安(an)排常常將空(kong)(kong)運(yun)作電源開(kai)關打開(kai)。

空運作(zuo)(zuo)是指數(shu)控車床(chuang)(chuang)全部運動軸都(dou)以(yi)G00的(de)(de)(de)速(su)度(du)(du)運行。要是在(zai)生(sheng)產加工(gong)(gong)時(shi)空運作(zuo)(zuo)電源開(kai)關未(wei)關的(de)(de)(de)話，cnc加工(gong)(gong)中(zhong)心忽略給(gei)的(de)(de)(de)進刀(dao)速(su)度(du)(du)，而以(yi)G00的(de)(de)(de)速(su)度(du)(du)運行，造成打刀(dao)、撞(zhuang)機(ji)(ji)床(chuang)(chuang)安全事故。空運作(zuo)(zuo)仿真(zhen)(zhen)模擬后沒(mei)有(you)再回機(ji)(ji)床(chuang)(chuang)坐標系。在(zai)校檢(jian)操作(zuo)(zuo)程(cheng)序時(shi)機(ji)(ji)床(chuang)(chuang)是鎖(suo)住不動的(de)(de)(de)，而cnc加工(gong)(gong)刀(dao)具取(qu)決于鋼件精(jing)加工(gong)(gong)在(zai)仿真(zhen)(zhen)模擬運行(肯(ken)定(ding)(ding)座(zuo)標和相(xiang)對座(zuo)標在(zai)變化)，這時(shi)候的(de)(de)(de)座(zuo)標與事實上具體位置不符合，須用回到(dao)機(ji)(ji)床(chuang)(chuang)坐標系的(de)(de)(de)形(xing)式，保(bao)證工(gong)(gong)業設備0點座(zuo)標與肯(ken)定(ding)(ding)、相(xiang)對座(zuo)標相(xiang)同。如果在(zai)校檢(jian)操作(zuo)(zuo)程(cheng)序后沒(mei)有(you)碰到(dao)難題就進行精(jing)加工(gong)(gong)操作(zuo)(zuo)步驟，將導致數(shu)控刀(dao)具的(de)(de)(de)碰撞(zhuang)。

cnc加(jia)工中心(xin)cnc機(ji)(ji)床(chuang)(chuang)(chuang)作(zuo)(zuo)為高精度的數(shu)控(kong)車床(chuang)(chuang)(chuang)，防碰是(shi)十分(fen)必需的，要求(qiu)作(zuo)(zuo)業者培養認認真真仔細當(dang)心(xin)的良好習(xi)慣，按(an)適當(dang)的方法操作(zuo)(zuo)機(ji)(ji)床(chuang)(chuang)(chuang)，減少機(ji)(ji)床(chuang)(chuang)(chuang)撞刀難題產生(sheng)。隨著技術(shu)應用的發(fa)展(zhan)壯大經常出現了加(jia)工過程中數(shu)控(kong)刀具損(sun)壞檢測、機(ji)(ji)床(chuang)(chuang)(chuang)防碰撞檢測、機(ji)(ji)床(chuang)(chuang)(chuang)自適應生(sheng)產加(jia)工等先進技術(shu)應用，這些可以科學規范維(wei)護cnc機(ji)(ji)床(chuang)(chuang)(chuang)。

CNC加工中心撞刀有下列幾方面的原因：

1、主軸(zhou)軸(zhou)承換刀具半徑補償(chang)具體位置不正確(que)或有出(chu)入。

2、主軸軸承定向不正確。

3、cnc加工尾(wei)座機械(xie)臂爪未正常開啟。

4、第(di)四(si)軸信號異常導出造成刀應(ying)用程序(xu)錯亂。

5、機床其他干(gan)擾(rao)信號造成(cheng)的(de)應用(yong)程序(xu)雜(za)亂。

以上(shang)就是毅鑫五金(jin)給大(da)家(jia)帶來的(de)關于“CNC加工撞刀(dao)的(de)原因”，希望(wang)可以幫到您(nin)!
