在充分利用CPU處理能力提高這一優(yōu)勢后，一些CNC系統(tǒng)的*小指令單位甚至可達(dá)到1納米。在指令單位縮小一千倍后，可獲得更高的加工精度，可使電機(jī)運(yùn)行得更平穩(wěn)。電機(jī)運(yùn)行的平穩(wěn)使得一些機(jī)床能夠在床身振動不加大的前提下，以更高的加速度運(yùn)行。 3.待加工軌跡監(jiān)控這一技術(shù)已被廣泛使用，該技術(shù)具有眾多性能差異，使其在低檔控制系統(tǒng)中的工作方式與控制系統(tǒng)中的工作方式得以區(qū)別開來?？偟膩碇v，CNC就是通過加工軌跡監(jiān)控來實現(xiàn)對程序的預(yù)處理，以此來確保能獲得更優(yōu)異的加速/減速控制。根據(jù)不同的CNC的性能，待加工軌跡監(jiān)控所需的程序塊數(shù)量從兩個到上百個不等，這主要取決于零件程序的*短加工時間和加速/減速的時間常數(shù)。一般而言，要想滿足加工要求，至少需要十五個待加工軌跡監(jiān)控程序塊。
