    • The controller attaches to a milling machine such as the well-known Bridgeport miller so as to adapt the machine to programmed automatic operation. Controls are associated with all axes of operation, however, the control is described herein with regard to X and Y axis control. A control panel for all operations is physically mounted in association with the X axis table. The basic components of the system include power motors for respectively controlling lead screws associated with X and Y axis control, electrical relays which in turn control the power motors, optical encoders which essentially read lead screw rotation, and a microprocessor. The electrical relays are used to start, stop, and set the directional rotation of the power motors upon commands from the microprocessor. The microprocessor has two basic modes of operation including a program mode in which the steps performed by the machinist are recorded for subsequent repeatability. The other mode is a run mode during which the microprocessor progresses through the previously established program from start to finish to thus reproduce a part.
    • 控制器连接到诸如众所周知的Bridgeport铣床之类的铣床,以使机器适应于编程的自动操作。 控制与所有操作轴相关联,但是这里关于X和Y轴控制来描述控制。 所有操作的控制面板与X轴表相关联地物理安装。 系统的基本部件包括用于分别控制与X和Y轴控制相关的导螺杆的电动马达,继电器控制功率马达,基本上读取螺杆旋转的光学编码器以及微处理器。 电气继电器用于根据微处理器的命令启动,停止和设置功率电机的定向旋转。 微处理器具有两种基本操作模式,包括程序模式,其中记录由机械师执行的步骤用于随后的可重复性。 另一种模式是一种运行模式,在此模式下,微处理器从开始到结束进行先前建立的程序,从而再现零件。
