一、数控系统的释义在生产工艺中,凡是以数字化代码形式并按照某种格式表示生产所需要的参数(诸如加工顺序、行程距离、主轴转速、进给速度、运动规律、容差指定、刀具选择等),再经过控制电路的记录、输送、变换、运算直至最后发出相应的信号以控制一台或若干台设备进行加工的方式称为数控(Numerical Control,简称NC)。数控的对象一般是位置、速度、角度等机械量,也可以是温度、压力、流量、颜色等物理 First, the numerical control system interpretation In the production process, all in digital form of code and in accordance with a format that the required parameters of production (such as processing sequence, travel distance, spindle speed, feed rate, movement, tolerance specified tool Selection, etc.), and then recorded by the control circuit, transmission, transformation, computing until the final issue of the corresponding signal to control one or several devices for processing is called NC (Numerical Control, referred to as NC). The object of numerical control generally is the position, the speed, the angle and so on the mechanical quantity, also may be the temperature, the pressure, the current capacity, the color and so on physics
