    摘要: Time pulses to be applied to a digital differential analyzer are intermittently eliminated by a gate circuit controlled by a reset input of a flip-flop circuit. The reset terminal of the flip-flop circuit receives speed control pulses corresponding to a predetermined machining speed and the set terminal thereof receives an output from an integrator having a register with contents in accordance with a machining distance of a machine tool. As an integral output corresponding to said register contents is obtained from the integrator, the clock pulses can be intermittently eliminated in a manner inversely proportional to the machining distance, thus providing a constant machining speed.

    摘要: A machine tool control system in which a programmable controller operates a machine to carry out a plurality of programmable functions. The controller includes a plurality of processor means, a first one of the processor means capable of pre-processing and forwarding control information to a second of said processor means, wherein said second processor means provides control information to control machine movement. Advantageously, the second processor means operates on a periodic time based interrupt method which greatly increases the accuracy of the machine.

    摘要: A pulse generator for use in a numerical control system wherein the pulse generator accepts pulses from an input pulse train and provides a plurality of digital drive signals corresponding to a plurality of axes of motion. The ratio of the frequencies of the drive signals is determined by the ratio of displacements of the axes of motion, and the highest frequency of the drive signals is approximately equal to the pulse train frequency.

    摘要: A numerical control system for a milling machine utilizes program tapes which include feedrate commands expressing the desired resultant rate of motion of the machine output member directly in inches per minute. The control system accepts this number and generates a pulse train having a rate proportional to the number by repeatedly adding the number into a register and generating the pulse train from the overflows from that register. This pulse train is provided to a circuit which generates a series of numerical values each equal to the square of the number of pulses received from the train at the time. The pulse commands to each of the individual axis servos are also provided to similar squaring circuits and the numerical values generated by the squaring circuits for these command pulse trains are summed and subtracted from numbers generated from the feedrate control pulse train. Control signals to the controller which generates the command pulse trains are provided so as to maintain an equality between the integrals of the two series of numbers, thereby commanding individual axis motions which will achieve a resultant motion in agreement with the feedrate command.
