    數控加工作為一種先進的加工方法,被廣泛地用于工業、艦船工業、電子工業等高精度,復雜零件的加工生產。在數控加工中,從零件圖紙到加工出合格的零件,是一環套一環既復雜而又嚴密的過程。每個階段的某個環節出問題,都會使加工過程中斷。下面結合具體加工實例分3個階段,對數控加工過程中一些關鍵因素進行分析,以使我們能對數控 加工加深了解,對加工生產有所幫助。
    1 工藝處理階段

    一般所用的數控機床,大多都不具備工藝處理能力。數控加工工藝處理的目的和普通機床類似。但由于數控機床加工過程的每一細節都必須預先確定,加工自動完成。因此,與普通機床的工藝準備相比,有著其自身的特點。

    1.1 對刀和換刀

    普通機床加工零件時,刀具與工件的位置關系是通過量具與手輪相互配合加以確立的,如果刀具位置不正確,可由操作者隨時加以調整。而數控加工,一次裝夾,有多把刀具參與加工,為確立各個刀型等參數輸入到計算機中,計算機通過坐標變換,使每把刀具與工件建立起對應關系。對于普通加工,對 刀問題不作為重要因素考慮。對于數控加工,只要使 用程序加工,就必須對刀,否則就會發生嚴重后果。普通加工換刀往往是通過操作感覺來控制,而數控加工必須認真考慮換刀位置,以防發生碰撞。

    1.2 裝夾方式的選擇

    考慮到數控加工每次裝夾都必須重新對刀,這樣會大大增加輔助加工時間,影響加工效率,同時也是對數控機床功能的“浪費”。所以,在數控加工中,盡可能做到一次裝夾后,能加工出全部的待加工表面,以充分發揮數控機床的功效,F以某零件部分加工過程予以說明。
