ABSTRACT:
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.
