可以看出，車銑復(fu)(fu)合加(jia)(jia)工(gong)機(ji)床(chuang)數控程(cheng)序編制難度非常大，而目前的(de)通用(yong)(yong)CAM 軟件(jian)用(yong)(yong)于(yu)車銑復(fu)(fu)合加(jia)(jia)工(gong)仍然存在(zai)很多缺陷和(he)(he)不足。為(wei)彌補這(zhe)些(xie)不足，在(zai)現有(you)通用(yong)(yong)CAD/CAM 軟件(jian)的(de)基礎上開發適用(yong)(yong)于(yu)產品工(gong)藝(yi)和(he)(he)復(fu)(fu)合加(jia)(jia)工(gong)設(she)備的(de)專用(yong)(yong)編程(cheng)系(xi)統是(shi)一種更為(wei)現實的(de)解決(jue)方案。這(zhe)一方面(mian)降低了軟件(jian)購置的(de)重復(fu)(fu)投(tou)資，同時也能避免由于(yu)編程(cheng)平臺不統一而造成的(de)工(gong)藝(yi)知識不能重用(yong)(yong)、人(ren)員配置復(fu)(fu)雜等缺陷。沈(shen)陽機(ji)床(chuang)銷售(shou)
