    • 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。

    • A system for testing key duplicating machines to determine the accuracy thereof. This system is provided with a pair of identical detector plates each of which are intended for alignment positioning of the key and key blank within the two vises of the key duplicating machine. Portions of the detector plates which are to be in contact with the vises are provided with an insulating surface, and portions of the remainder of the detector plates are electrically conductive and are exposed for contact. An electrical circuit is provided which attaches to these detector plates such that electrical continuity can be determined visually when the guide member of the key duplicating machine contacts the detector plate held in the appropriate vise. In a similar manner, the continuity is determined when the cutter contacts the second detector plate when the second detector plate is held in the vise which would normally hold a key blank and when continuity is indicated between both systems simultaneously, the key duplicating machine is in proper alignment. When the indication is not simultaneous, the guide member of the key duplicating machine may be adjusted in a appropriate direction such that simultaneous indication of continuity is achieved. Through use of the system any key duplicating machine may be periodically checked to determine its accuracy.
    • 用于测试密钥复制机器以确定其准确性的系统。 该系统设置有一对相同的检测器板,每个检测器板用于将钥匙和钥匙坯件对准定位在钥匙复制机器的两个护罩内。 与屏障接触的检测器板的一部分设置有绝缘表面,并且其余检测器板的部分导电并且暴露以进行接触。 提供了一种电路,其连接到这些检测器板,使得当密钥复制机的引导构件接触保持在适当的台钳中的检测器板时,可视觉地确定电连续性。 以类似的方式,当第二检测器板保持在通常保持钥匙坯件的台钳中时,当两个系统之间连续性被指示时,切割器接触第二检测器板时,确定连续性,密钥复制机器处于 正确对齐。 当指示不是同时的时,可以在适当的方向上调整密钥复制机的引导部件,从而实现连续性的同时指示。 通过使用系统,可以定期检查任何密钥复制机,以确定其准确性。
