上一年機床(chuang)職(zhi)業(ye)出(chu)口同比(bi)增(zeng)加22.1%，出(chu)口總額達116.3億美元，與2013年比(bi)較(jiao)有小幅增(zeng)加。在總結(jie)2014年職(zhi)業(ye)運轉狀況(kuang)時得出(chu)判別，職(zhi)業(ye)主體仍未走(zou)出(chu)下行區間，但起伏趨(qu)緩。估計2015年機床(chuang)東西職(zhi)業(ye)下行壓力大，國(guo)產(chan)機床(chuang)銷售(shou)額有望與2014年相等，調(diao)整產(chan)業(ye)結(jie)構，擴展中高端產(chan)品線仍是本年公司開展的重要課題。沈陽機床(chuang)銷售(shou)。

可以看出(chu)，車銑(xian)復合(he)加(jia)工機床數控程(cheng)(cheng)序編制(zhi)難度非常(chang)大，而(er)目(mu)前的通用(yong)(yong)CAM 軟件用(yong)(yong)于(yu)車銑(xian)復合(he)加(jia)工仍然存在很多缺(que)陷(xian)和不足。為彌補這些不足，在現有通用(yong)(yong)CAD/CAM 軟件的基礎上開發適用(yong)(yong)于(yu)產品(pin)工藝和復合(he)加(jia)工設備的專(zhuan)用(yong)(yong)編程(cheng)(cheng)系統是一種更為現實的解決(jue)方(fang)案。這一方(fang)面降(jiang)低了軟件購(gou)置(zhi)的重復投資(zi)，同時也能(neng)避免由于(yu)編程(cheng)(cheng)平(ping)臺不統一而(er)造成的工藝知識不能(neng)重用(yong)(yong)、人員配(pei)置(zhi)復雜等缺(que)陷(xian)。沈陽機床銷售
