Controller for multiple-axis machine |
摘要 |
Movement of a tool relative to a workpiece along each one of a plurality of axes is controlled by digitally providing a train of digital pulses to an electromechanical actuator and by digitally modulating the pulse widths (without an intervening conversion to analog form) so that electrical energy is carried in the pulse train at rates which will cause the actuator to tend to produce an intended sequence of speeds and positions.
