多功能金屬激光焊接(jie)機微機控制系統的(de)概述

市場上有一些可定制的多功能金屬激光焊接機，它不僅(jin)(jin)僅(jin)(jin)可以(yi)完成激(ji)光焊(han)(han)接工(gong)(gong)作(zuo)，還可以(yi)完成金屬切割等系(xi)統(tong)(tong)的工(gong)(gong)作(zuo)。由于此類激(ji)光焊(han)(han)接機的功能(neng)較多，所以(yi)需要加強(qiang)其控制系(xi)統(tong)(tong)的設(she)計，才能(neng)讓設(she)備實現自動化加工(gong)(gong)。多功能(neng)金屬激(ji)光焊(han)(han)接機的控制系(xi)統(tong)(tong)稱為微(wei)機控制系(xi)統(tong)(tong)，下面我們就以(yi)某個焊(han)(han)接設(she)備的系(xi)統(tong)(tong)為例進行詳細了解。
