3、铣床的工作原理：数控铣床是一种高度自动化的机床，在加工工艺与加工表面形成方法上，与普通机床是基本相同的，最根本的不同在于实现自动化控制的原理与方法上。数控铣床是用数字化的信息来实现自动化控制的，将与加工零件有关的信息工件与刀具相对运动轨迹的尺寸参数（进给执行部件的进给尺寸），切削加工的工艺参数（主运动和进给运动的速度、切削深度等），以及各种辅助操作（主运动变速、刀具更换、冷却润滑液关停、工件夹紧松开等）等加工信息用规定的文字、数字和符号组成的代码，按一定的格式编写成加工程序单，将加工程序通过控制介质输入到数控装置中，由数控装置经过分析处理后，发出各种与加工程序相对应的信号和指令控制机床进行自动

4、加工。数控铣床的数字控制的原理与过程通过下述的数控铣床组成可得到更明确的说明。 3. 数控铣削的加工过程： 首先根据零件加工图样进行工艺分析，确定加工方案、工艺参数和位移数据。 用规定的程序代码和格式规则编写零件加工程序单；或用自动编程软件进行CAD/CAM工作，直接生成零件的加工程序文件。 程序的输入和输出。手工编写的程序通过数控机床的操作面板输入，软件生成的程序通过传输通讯技术直接传输到机床。 将输入的数控单元的加工程序进行试运行和刀具路径模拟等。 通过机床的正确操作，运行程序，完成零件的加工。二、数控机床的操作过程，试切对刀的操作要点1. 手工编程操作将编制的加工程序输入数控系统，具体的
