Abstract: A machine control system including a programmable machine function controller comprised of a logic processor and a data processor. The logic processor is responsive to first devices on a machine, e.g. limit switches and push buttons, for controlling second devices on the machine, e.g. motor starters and solenoids, in accordance with a program representing a desired machine operation. The data processor operates asynchronously with the logic processor but responds thereto for selecting programs of arithmetic instructions relating to the machine operation. The system includes a panel of push buttons, lights and read-outs located remotely from the controller. Signals are transmitted between the controller and the panel using asynchronously operating receiver/transmitters which multiplex and transfer the signals on a serial basis. The machine includes at least one movable member in mechanical communication with a driving mechanism. The controller employs circuits which are responsive to the data processor and logic processor for producing signals to the driving mechanism to control the motion of the movable element.

Abstract: A computer-controlled hydraulic press brake includes an actuator and control system which automatically provides variable pre-programmable ram opening and closing strokes. A microprocessor within the control system responds to stroke parameters entered by the operator and an encoder-generated signal indicative of ram position to generate a velocity command signal defining a velocity profile for positioning the ram to the stroke limits. Closed-loop servo systems associated with each ram cylinder respond to the velocity command signal to cause movement of the ram in accordance with the velocity profile. A ram leveling circuit responsive to individual position sensors associated with respective sides of the ram compensates for ram tilt by simultaneously applying complimentary correction signals to the respective servo systems. A second velocity profile may be generated in response to stored parameters to position a back gauge concurrently with ram movement by means of a second motor drive servo system.

Abstract: A system and method for initializing a plurality of mechanical elements of a machine includes a plurality of housings and an uncoordinated motion controller. The housings are coupled to the mechanical elements and include at least a motor controller electrically connected to a motor. Each of the motor controllers have an associated position sensing component for sensing the position of the associated mechanical element along one axis. The uncoordinated motion controller instructs the motor controllers to operate its associated motor until the associated mechanical element reaches an initialization position. The velocity and acceleration profile of the respective motors are independent of each other, such that each of the motors moves its associated mechanical element in uncoordinated motion until each mechanical element reaches its initialization position. A multi-node daisy chained data bus electrically connects the uncoordinated motion controlling means and the motor controllers in series.

Abstract: This invention relates to a computer numerical control (CNC) machine tool system having a novel terminal controller and system therefor to control a machine tool generally with at least two axes and more probably three, with stepping motor controls for point-to-point positioning of the machine tool to an almost infinite variety of steps (generally not more than 200). The novelty resides in the ease of programming directly on the terminal controller of the CNC machine tool system. Generally at least some editing and offsets will be programmed from the machine tool.The terminal controller consists of a microprocessor with some RAM and ROM, together with address and data bus plus I/O for magnetic tape handling and display for 6 to 8 digits in each of the X and Y positions, together with numeric keyboard for data input to the program steps and functional keys to control operation-automatic, manual and step-by-step, as well as controls for program input from tape to memory and memory to tape.Particular features include the ease of inputting a program and preparing a tape and then editing the tape while in operation. Further features include circular and linear interpolation. For circular interpolation there are no quadrant limitations and a full or partial circle may be cut.
