数控加工是指，由控制系统发出指令使刀具作符合要求的各种运动，以数字和字母形式表示工件的形状和尺寸等技术要求和加工工艺要求进行的加工。 它泛指在数控机床上进行零件加工的工艺过程。
数控机床是一种用计算机来控制的机床，用来控制机床的计算机，不管是专用计算机、还是通用计算机都统称为数控系统。数控机床的运动和辅助动作均受控于数控系统发出的指令。而数控系统的指令是由程序员根据工件的材质、加工要求、机床的特性和系统所规定的指令格式（数控语言或符号）编制的。数控系统根据程序指令向伺服装置和其它功能部件发出运行或终断信息来控制机床的各种运动。当零件的加工程序结束时，机床便会自动停止。任何一种数控机床，在其数控系统中若没有输入程序指令，数控机床就不能工作。机床的受控动作大致包括机床的起动、停止；主轴的启停、旋转方向和转速的变换；进给运动的方向、速度、方式；刀具的选择、长度和半径的补偿；刀具的更换，冷却液的开起、关闭等。
