切削用量包括：主軸轉(zhuǎn)速、切削深度、進給速度。在選擇數(shù)控銑床的切削用量時，如果是粗加工，一般以提高生產(chǎn)率為主，但也要考慮經(jīng)濟性和加工成本，可選擇較大的切削深度和進給速度；要是半精加工和精加工，應(yīng)在保證加工質(zhì)量的前提下，兼顧效率、經(jīng)濟性和加工成本；刀具做空程運動時應(yīng)設(shè)定盡可能高的進給速度。具體數(shù)值應(yīng)根據(jù)車床說明書、切削用量手冊，并結(jié)合經(jīng)驗而定。
5.實行刀具預(yù)調(diào)和自動測狼，減少占機調(diào)整時間
數(shù)控車床加工過程中往往要用到多把不同的刀具，如果刀具不能預(yù)先調(diào)好，就需要操作者把每一把刀具都安裝到主軸上，慢慢地確定它們的準確長度和直徑。然后，通過CNC控制面上的按鍵用人工輸入。如果使用對刀儀，它可以精確測量出刀具的直徑和長度，減少車床占用時間，提高首件合格率，大大提升數(shù)控銑床的生產(chǎn)效率。
6.靈活運用數(shù)控車床的各種輔助功能及宏程序
數(shù)控車床具有刀具半徑和長度補償功能，通過改變刀具補償?shù)姆椒◤浹a刀具尺寸誤差，以同一加工程序?qū)崿F(xiàn)分層銑削和粗、精加工或用于提高加工精度，并可用同一加工程序加工配合件。

運用宏程序最大的特點就是將有規(guī)律的形狀或尺寸用最短的程序表示出來，而且車床在執(zhí)行此類程序時，較執(zhí)行CAD/CAM軟件生成的程序更加快捷，反應(yīng)更迅速。宏程序可以使用變量，并給變量賦值，變量之間可以運算，程序運行可以跳轉(zhuǎn)，可以形成模塊化加工程序，應(yīng)用時只需要把零件信息、加工參數(shù)等輸入相應(yīng)模塊的調(diào)用語句中，大大縮短程序編制和輸入時間。
