Overseas numerical control cad / cam system that function is very strong and system " s price is high , it is difficult that gain appliance and expansion in middle and small enterprise ; we have many domestic numerical control cad / gam software , each software has the special features and is not perfect , many ways need to study , for the reasons it is necessary to develop the numerical control programming system which face middle and small enterprises and has independent copyright 數(shù)控機(jī)床在工業(yè)生產(chǎn)中得到廣泛應(yīng)用,相應(yīng)的數(shù)控編程技術(shù)也迅猛的發(fā)展。國(guó)外的數(shù)控cad cam軟件功能非常強(qiáng)大,但是價(jià)格高,在中小企業(yè)很難推廣應(yīng)用;而國(guó)產(chǎn)的數(shù)控cad cam軟件也很多,它們各有特色,并不完善,有很多需要研究;所以有必要開(kāi)發(fā)一個(gè)面向中小企業(yè)具有自主版權(quán)的數(shù)控編程系統(tǒng)。
