車(che)銑(xian)復合機(ji)床加(jia)工(gong)(gong)技(ji)術(shu)的發(fa)展，也對數控(kong)編程技(ji)術(shu)提出了更高的要求，這也是(shi)制(zhi)約(yue)車(che)銑(xian)復合加(jia)工(gong)(gong)機(ji)床在實(shi)際(ji)生產(chan)應(ying)用中的一個瓶(ping)頸環節。與傳統的數控(kong)編程技(ji)術(shu)相比，車(che)銑(xian)復合加(jia)工(gong)(gong)機(ji)床的程序編制(zhi)難點(dian)主要體現在以下(xia)幾個方面(mian)。沈陽機(ji)床：

　　(1)工(gong)(gong)(gong)藝種類繁雜。對于工(gong)(gong)(gong)藝人員來說，不(bu)僅要能(neng)掌握數控車削、多軸銑削、鉆孔等多種加工(gong)(gong)(gong)方式的編程(cheng)方法，而且對于工(gong)(gong)(gong)序(xu)間的銜接與(yu)進(jin)退刀方式需(xu)要準確界定(ding)。因此(ci)在(zai)進(jin)行數控編程(cheng)時，需(xu)要對當(dang)前工(gong)(gong)(gong)序(xu)加工(gong)(gong)(gong)完(wan)成后的工(gong)(gong)(gong)序(xu)模(mo)型和加工(gong)(gong)(gong)余量的分布有直觀(guan)的認識，以便于下一(yi)道(dao)工(gong)(gong)(gong)序(xu)的程(cheng)序(xu)編制和進(jin)退刀的設置(zhi)。

　　(2)程(cheng)(cheng)(cheng)序(xu)(xu)編(bian)(bian)制過(guo)程(cheng)(cheng)(cheng)中的(de)(de)(de)串并(bing)行(xing)順序(xu)(xu)的(de)(de)(de)確定(ding)必須嚴格按(an)照工(gong)(gong)(gong)(gong)藝路(lu)線確定(ding)。許多(duo)零件在(zai)車銑復合(he)(he)加(jia)工(gong)(gong)(gong)(gong)中心上(shang)加(jia)工(gong)(gong)(gong)(gong)時(shi)可實現(xian)(xian)從毛料到(dao)成品的(de)(de)(de)完整(zheng)加(jia)工(gong)(gong)(gong)(gong)，因(yin)此加(jia)工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)序(xu)(xu)的(de)(de)(de)編(bian)(bian)制結果必須同工(gong)(gong)(gong)(gong)藝路(lu)線保持一致。同時(shi)，對(dui)于多(duo)通(tong)道(dao)并(bing)行(xing)加(jia)工(gong)(gong)(gong)(gong)也需(xu)要在(zai)數控加(jia)工(gong)(gong)(gong)(gong)程(cheng)(cheng)(cheng)序(xu)(xu)編(bian)(bian)制的(de)(de)(de)過(guo)程(cheng)(cheng)(cheng)中進行(xing)綜合(he)(he)考慮。可見，為實現(xian)(xian)高效的(de)(de)(de)復合(he)(he)加(jia)工(gong)(gong)(gong)(gong)應該發展工(gong)(gong)(gong)(gong)藝- 編(bian)(bian)程(cheng)(cheng)(cheng)- 仿真一體(ti)化(hua)的(de)(de)(de)工(gong)(gong)(gong)(gong)藝解決方(fang)案。

　　(3)對于(yu)車銑復合(he)加工機床的(de)(de)某些功能(neng)，目前的(de)(de)通用CAM 軟(ruan)件(jian)(jian)尚(shang)不(bu)支持。與常規單(dan)臺設備(bei)加工相比，車銑復合(he)加工具備(bei)的(de)(de)機床運動(dong)和加工功能(neng)要(yao)復雜(za)的(de)(de)多(duo)，目前的(de)(de)通用CAM 軟(ruan)件(jian)(jian)尚(shang)不(bu)足以完全支持這些先進功能(neng)的(de)(de)程序編(bian)制，如在(zai)線測量、鋸斷、自(zi)動(dong)送(song)料、尾座控制等。因此，利(li)用通用CAM 軟(ruan)件(jian)(jian)編(bian)制出來的(de)(de)程序仍(reng)然需要(yao)大量的(de)(de)手工或(huo)交互的(de)(de)方式才能(neng)應用于(yu)自(zi)動(dong)化的(de)(de)車銑復合(he)加工。

　　(4)加(jia)工(gong)(gong)程(cheng)序(xu)(xu)(xu)的(de)(de)(de)(de)整(zheng)合。目前通用(yong)CAM 軟件(jian)編(bian)制(zhi)完成后的(de)(de)(de)(de)NC 程(cheng)序(xu)(xu)(xu)之間是相(xiang)互獨立的(de)(de)(de)(de)，要實現車銑復(fu)合這樣復(fu)雜的(de)(de)(de)(de)自動化完整(zheng)加(jia)工(gong)(gong)，需要對(dui)這些(xie)獨立的(de)(de)(de)(de)加(jia)工(gong)(gong)程(cheng)序(xu)(xu)(xu)進(jin)行集成和整(zheng)合。這種整(zheng)合必須以(yi)零件(jian)的(de)(de)(de)(de)工(gong)(gong)藝路線為(wei)指導，首先確(que)定出哪些(xie)程(cheng)序(xu)(xu)(xu)是并行的(de)(de)(de)(de)，然(ran)后對(dui)不同工(gong)(gong)藝方法的(de)(de)(de)(de)加(jia)工(gong)(gong)順序(xu)(xu)(xu)進(jin)行確(que)定，并給出準確(que)的(de)(de)(de)(de)換(huan)刀、裝卡更換(huan)、基(ji)準轉化以(yi)及進(jin)退刀指令(ling)等(deng)。

　　可(ke)以看出，車銑復合加工機(ji)床(chuang)數(shu)控程序編制難度非常大，而目前的(de)(de)通用(yong)(yong)CAM 軟(ruan)件用(yong)(yong)于車銑復合加工仍(reng)然(ran)存在很多缺(que)陷和不(bu)足。為彌補這些(xie)不(bu)足，在現(xian)有通用(yong)(yong)CAD/CAM 軟(ruan)件的(de)(de)基礎上開發(fa)適(shi)用(yong)(yong)于產品(pin)工藝(yi)和復合加工設備的(de)(de)專用(yong)(yong)編程系統(tong)是一(yi)(yi)種(zhong)更為現(xian)實的(de)(de)解決方案。這一(yi)(yi)方面(mian)降低了軟(ruan)件購置的(de)(de)重(zhong)復投資(zi)，同時也能避(bi)免由于編程平(ping)臺不(bu)統(tong)一(yi)(yi)而造(zao)成(cheng)的(de)(de)工藝(yi)知識不(bu)能重(zhong)用(yong)(yong)、人員配置復雜等缺(que)陷。沈陽機(ji)床(chuang)銷售
