5 結(jié)束語
臺(tái)達(dá)PM20運(yùn)動(dòng)控制器在執(zhí)行圓弧插補(bǔ)以及執(zhí)行連續(xù)性的動(dòng)作流程方面更接近于專業(yè)數(shù)控系統(tǒng),有著PLC所不能比擬的優(yōu)勢,盡管在執(zhí)行程序流程的靈活性方面,和PLC還是有一定的距離。
用管材制造的彎曲零件,無論是平面彎曲件,還是空間彎曲件,除大量應(yīng)用于氣體、液體的輸送管路外,在金屬結(jié)構(gòu)中的應(yīng)用也十分廣泛。因此管材彎曲成形工藝是備受關(guān)注并得到迅速發(fā)展的重要領(lǐng)域,開展這方面的研究工作,具有十分重要的意義。
