數控主要原理：是利用數字化程序對機械運動及加工過程進行控制的一種方法。先將被加工零件的有關信息（幾何信息、工藝信息等）表示成數字控制裝置所能接受的指令信息，然后由數字控制裝置對指令信息和反饋信息進行處理，計算出機床各坐標運動的控制信息，后將控制信息轉換為機床各坐標部件的實際運動，加工出符合設計要求的零件。
數控系統由三大部分組成：控制系統，伺服系統和位置測量系統。
1）控制系統按加工工件程序進行插補運算，發出控制指令到伺服驅動系統；控制系統主要由總線、CPU、電源、存貯器、操作面板和顯示屏、位控單元、可編程序控制器邏輯控制單元以及數據輸入/輸出接口等組成。還包括一個通訊單元，它可完成CNC、PLC的內部數據通訊和外部高次網絡的連接。
2）伺服驅動系統將控制指令放大，由伺服電機驅動機械按要求運動；伺服驅動系統主要包括伺服驅動裝置和電機。
3）測量系統檢測機械的運動位置或速度，并反饋到控制系統，來修正控制指令。位置測量系統主要是采用長光柵或圓光柵的增量式位移編碼器。
這三部分有機結合，組成完整的閉環控制的數控系統。
