數控技術CNC加工常用刀具(ju)講解

由于(yu)銑(xian)刀(dao)在目前的(de)切(qie)削加工中，幾乎可取代大部分之傳統切(qie)削刀(dao)具，故無論在銑(xian)刀(dao)之材料、造型(xing)、結(jie)構…等等之設(she)計制造上，不但種類極為繁多而(er)且(qie)復雜。現(xian)在僅(jin)就下列一般模具銑(xian)削加工中常用之銑(xian)刀(dao)種類作說明介紹(shao)。

1.銑刀的種類

在(zai)模(mo)具銑(xian)削加(jia)(jia)工中(zhong)，由(you)于模(mo)具本(ben)身即是(shi)有復(fu)雜造型之工件(jian)(jian)，在(zai)考慮切削效率、刀(dao)(dao)具壽(shou)命以及工件(jian)(jian)形狀(zhuang)…等的因素下，因此要只(zhi)使用(yong)單一種(zhong)形狀(zhuang)之銑(xian)刀(dao)(dao)便可將模(mo)具加(jia)(jia)工完成是(shi)不可能的。所以在(zai)模(mo)具加(jia)(jia)工中(zhong)常會需要用(yong)到不同形狀(zhuang)的銑(xian)刀(dao)(dao)來加(jia)(jia)工模(mo)具，一般模(mo)具加(jia)(jia)工普(pu)遍使用(yong)的銑(xian)刀(dao)(dao)有以下三種(zhong): A、端銑(xian)刀(dao)(dao);B、球刀(dao)(dao);C、圓鼻(bi)刀(dao)(dao)。

如何在(zai)加(jia)(jia)(jia)(jia)工(gong)鋁材料時確(que)保數(shu)控(kong)機床的(de)(de)(de)(de)尺寸？可避免的(de)(de)(de)(de)因(yin)素(su)：1。加(jia)(jia)(jia)(jia)工(gong)過程中的(de)(de)(de)(de)大多數(shu)實際加(jia)(jia)(jia)(jia)工(gong)誤(wu)(wu)差都是由不(bu)合(he)(he)理(li)的(de)(de)(de)(de)加(jia)(jia)(jia)(jia)工(gong)過程引起的(de)(de)(de)(de)。確(que)保基(ji)本加(jia)(jia)(jia)(jia)工(gong)工(gong)藝（如銑削和CNC加(jia)(jia)(jia)(jia)工(gong)，五金配件(jian)加(jia)(jia)(jia)(jia)工(gong)，一(yi)粗，細(xi)，一(yi)面，一(yi)孔(kong)，一(yi)面）在(zai)“小臉”的(de)(de)(de)(de)基(ji)礎(chu)上(shang)(shang)或(huo)使(shi)用(yong)基(ji)本加(jia)(jia)(jia)(jia)工(gong)工(gong)藝等由于(yu)“減少(shao)了夾緊次數(shu)，嘗試使(shi)用(yong)組合(he)(he)夾具”，因(yin)此鋁部件(jian)上(shang)(shang)的(de)(de)(de)(de)鐵屑(xie)造成的(de)(de)(de)(de)加(jia)(jia)(jia)(jia)工(gong)誤(wu)(wu)差小化(hua)，因(yin)為鋁部件(jian)非常柔軟(ruan)并且不(bu)包括鐵屑(xie)。很(hen)容易在(zai)鋁制零件(jian)中引起加(jia)(jia)(jia)(jia)工(gong)誤(wu)(wu)差。例如，在(zai)FANUC或(huo)華(hua)中加(jia)(jia)(jia)(jia)工(gong)中心，應(ying)使(shi)用(yong)G83指(zhi)令(ling)盡可能使(shi)用(yong)深(shen)孔(kong)，以便可以排出鐵屑(xie)而(er)不(bu)是G73指(zhi)令(ling)。
