軋輥磨床是一種具有特殊工藝要求的重要工業生產設備，主要用于磨削軋制機中的各種具有中凸度或中凹度（ 輥形曲線）的圓柱體軋輥，屬于專用磨床系列。軋輥磨床具有以下幾個運動軸：縱向的Z軸，橫向的X軸，偏心套的U軸，測量裝置的X1和X2軸，工件的轉動，砂輪的轉動。
由于軋輥的輥形曲線形狀復雜及其精度控制高的特殊要求，我們研究開發新一代基于SINUMERIK 840D平臺的納米級數控系統，與軋輥傳統加工工藝相結合，作為實現軋輥納米級（10-6mm）的高速高精度的磨削加工控制，以通常的 為單位輸入數控指令，以納米為單位進行精密的位置計算，輸出控制各伺服軸運動的位置指令的“納米級插補器”和執行該指令的高速高響應的伺服控制器。該控制器使用高速CPU和的伺服電動機及精密的位置測量與反饋元件，實現納米級進給。最終實現軋輥磨床極為平滑和高速高精度進給磨削及實現高性能、高品質軋輥磨削。
本文主要介紹基于西門子的開放式SINUMERIK 840D為控制平臺，以軋輥磨床MK8463為控制對象，以OEM開發包為工具，利用高級編程語言Visual Basic6.0 和ViSual C++6.0等，應用智能化技術和專家工藝系統開發實現的智能化納米級數控系統的結構體系，功能模塊劃分和主要模塊的實現方法。
一、SINUMERIK 840D的開放性
開放式CNC系統是對傳統封閉式數控系統的根本突破，是當今數控技術發展的主流。在控制系統的開放性方面，不同開發商及研究機構采用的解決方案也不同。按開放的層次不同可分3 種途徑，開放層次不同，實現的難度不等，獲得的開放效果也相差很大，如圖1所示。圖中，虛線將控制系統劃分為人機控制（Man-Machine Control,MMC）層和控制內核層兩個層面，其中控制內核是CNC系統完成實時加工過程調度和控制的核心部分，一般和系統實時性相聯系。3種方式就是基于對這種兩個層面開放的不同處理來區分的。
