數(shu)(shu)控(kong)加工與(yu)傳(chuan)統機(ji)加工的區別。裝(zhuang)夾(jia)(jia)(jia)及夾(jia)(jia)(jia)具：在(zai)數(shu)(shu)控(kong)加工工藝(yi)中(zhong)，不僅需要夾(jia)(jia)(jia)具和機(ji)床的坐標方向要保證相對固定，而(er)(er)且還(huan)對零件(jian)和機(ji)床坐標系(xi)(xi)的尺寸關系(xi)(xi)進行協(xie)調。而(er)(er)且裝(zhuang)夾(jia)(jia)(jia)過程(cheng)中(zhong)需要對定位和夾(jia)(jia)(jia)緊這(zhe)兩個步驟進行有(you)效的控(kong)制。而(er)(er)且傳(chuan)統機(ji)加工工藝(yi)下，由于機(ji)床自(zi)身的加工能力有(you)限，數(shu)(shu)控(kong)加工中(zhong)心報價，所以需要進行在(zai)加工過程(cheng)中(zhong)進行多(duo)次裝(zhuang)夾(jia)(jia)(jia)。而(er)(er)且需要利用(yong)夾(jia)(jia)(jia)具，這(zhe)就導致(zhi)夾(jia)(jia)(jia)具在(zai)設計和制造上的費(fei)用(yong)較高，無形(xing)中(zhong)增加了產品的生產成本(ben)。
