數控機械加工是(shi)一種(zhong)自(zi)動化加工(gong)(gong)(gong)(gong)設備(bei)。普通機(ji)(ji)床(chuang)(chuang)加工(gong)(gong)(gong)(gong)方式是(shi)由操作(zuo)人員操縱機(ji)(ji)床(chuang)(chuang)手輪(lun)使刀具沿工(gong)(gong)(gong)(gong)件表(biao)面移動進(jin)行加工(gong)(gong)(gong)(gong)。而(er)采用(yong)數控(kong)(kong)機(ji)(ji)床(chuang)(chuang)進(jin)行加工(gong)(gong)(gong)(gong)時,不需(xu)要人工(gong)(gong)(gong)(gong)參與,數控(kong)(kong)機(ji)(ji)床(chuang)(chuang)的加工(gong)(gong)(gong)(gong)過(guo)程是(shi)在加工(gong)(gong)(gong)(gong)程序指令下,數控(kong)(kong)系統控(kong)(kong)制機(ji)(ji)床(chuang)(chuang)自(zi)動完成(cheng)零件的加工(gong)(gong)(gong)(gong),那其中達到高效(xiao)率生(sheng)產加工(gong)(gong)(gong)(gong)必須滿足(zu)以(yi)下九大要點:
1、確保CNC精密機械加工 刀具切削性能(neng)穩定(ding)可靠(kao)
刀(dao)(dao)具(ju)(ju)切削性(xing)能和壽命(ming)要穩定可靠,用數控機床進(jin)行(xing)加(jia)工(gong)(gong)(gong)時,對(dui)刀(dao)(dao)具(ju)(ju)實行(xing)定時強(qiang)制(zhi)換刀(dao)(dao)或由控制(zhi)系統對(dui)刀(dao)(dao)具(ju)(ju)壽命(ming)進(jin)行(xing)管理,同一批數控刀(dao)(dao)具(ju)(ju)的切削性(xing)能和刀(dao)(dao)具(ju)(ju)不得有(you)較大差(cha)異,要避免頻繁地停(ting)機更換刀(dao)(dao)或造(zao)成加(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)件大量報(bao)廢。
2、保證CNC精密機械加工刀具的較長使用壽命
刀(dao)具應(ying)有較高的(de)(de)壽命,應(ying)選用切削性(xing)能、耐磨性(xing)高的(de)(de)涂(tu)層刀(dao)具以及(ji)合理的(de)(de)選擇切削用量。
3、避免CNC精密機械加工刀具損耗
確(que)保(bao)可(ke)靠地斷屑(xie)、卷(juan)屑(xie)和排屑(xie),紊亂切屑(xie)系統會給(gei)自(zi)動化生產帶來極(ji)大的(de)危害,造成刀(dao)具(ju)崩刃,產生各類因素不同(tong)程度(du)的(de)耗損(sun)。
4、確保CNC精密機械加工刀(dao)具(ju)的狀(zhuang)態(tai)轉(zhuan)換
保證能快(kuai)速(su)的轉位、更換(huan)刀片以及(ji)自動換(huan)刀等操作。
5、科(ke)學合理調(diao)整CNC精密機(ji)械加工刀具狀態。
能迅速、準確地調整刀具(ju)對零件的(de)加工尺寸,刀具(ju)原始定(ding)位(wei)點等。
6、根據(ju)數控特(te)點選擇CNC精密機械加工刀具。
必須從數控加工特(te)點出(chu)發(fa),訂(ding)制數(shu)控(kong)刀具的標準(zhun)化(hua),系列化(hua)和通(tong)用(yong)化(hua)結構體系,這樣才能快速購買到(dao)合適(shi)的刀具。
7、建立數據庫及管理系統
應建(jian)立完整的數(shu)據庫及(ji)管理(li)系統,數(shu)控刀具(ju)的種類(lei)多,管理(li)較(jiao)復雜,既要對所有(you)刀具(ju)進(jin)行(xing)自動識別、記憶其(qi)規格尺寸(cun),存入(ru)位置、已切削時間(jian)和(he)剩余(yu)壽命(ming)等,其(qi)次對刀具(ju)的更換、運(yun)送、刀具(ju)尺寸(cun)預調(diao)等進(jin)行(xing)管理(li)。
8、編寫完善(shan)的(de)刀具信(xin)息系統
具備(bei)完善的刀(dao)具組裝、熟悉機床刀(dao)具預調、編碼標識與識別系統。
9、時(shi)刻監控(kong)刀具狀態
設立刀具(ju)磨損(sun)和破損(sun)在線監控(kong)系(xi)統。
數控機械加工是(shi)一種用加(jia)(jia)工(gong)機(ji)械對(dui)工(gong)件(jian)的(de)(de)(de)外形(xing)尺寸或(huo)性(xing)能(neng)進行改變的(de)(de)(de)過(guo)程也是(shi)非標機(ji)械加(jia)(jia)工(gong)。按被加(jia)(jia)工(gong)的(de)(de)(de)工(gong)件(jian)處于的(de)(de)(de)溫(wen)度狀態﹐分爲(wei)(wei)冷加(jia)(jia)工(gong)和熱加(jia)(jia)工(gong)。一般(ban)(ban)在常溫(wen)下(xia)加(jia)(jia)工(gong),并且不引(yin)起工(gong)件(jian)的(de)(de)(de)化學(xue)或(huo)物相變化﹐稱冷加(jia)(jia)工(gong)。一般(ban)(ban)在高于或(huo)低于常溫(wen)狀態的(de)(de)(de)加(jia)(jia)工(gong)﹐會(hui)引(yin)起工(gong)件(jian)的(de)(de)(de)化學(xue)或(huo)物相變化﹐稱熱加(jia)(jia)工(gong)。冷加(jia)(jia)工(gong)按加(jia)(jia)工(gong)方式的(de)(de)(de)差別可分爲(wei)(wei)切削(xue)加(jia)(jia)工(gong)和壓力(li)加(jia)(jia)工(gong)。
