摘要： A programmable sequence controller is disclosed which includes a controller memory having at least one read-only memory unit for storing a sequence program comprising a series of instructions each including an operation code and address information. An operation control device is also provided for examining an external input in accordance with an appropriate instruction. An input network permits application of external inputs designated by the address information to the operation control device, and an output network is provided for transmitting a control signal based on the examination result from the operation control device. A program input network including a read-write memory is provided for storing a part of the sequence program, which part is loadable in one read-only memory unit. A program changing device is provided for changing the partial sequence program loaded in the read-write memory, and a transfer system is included for immediately transferring the changed sequence program into a read-only memory unit.

摘要： A method for teaching a machining line to be machined is disclosed. A borderline is formed along the machining line on a workpiece. Then, a borderline sensor is moved across the borderline at each sensing position. The positions of the sensor are stored as a teaching position at each time when the borderline is detected by the sensor. The sensing interval between each teaching position is automatically adjusted according to the change in the curvature of the borderline. At the place where the curvature of the borderline becomes large, the sensing interval is shortened in order to maintain teaching accuracy.

摘要： A feed control apparatus wherein a servomotor control device responsive to feed pulses distributed from a numerical controller controls a d.c. servomotor to advance a grinding wheel carriage of a grinding machine through the rotation of a feed screw successsively at a speed-up feed rate, a rapid feed rate, a slow-down feed rate and a grinding feed rate. A detection device is provided, which outputs a velocity checking signal to an abnormality confirmation device when the carriage reaches a velocity checking point defined within a slow-down feed range. When confirming that the feed rate of the carriage has exceeded a reference feed rate lower than the rapid feed rate, the abnormality confirmation device applies a stop signal to an emergency stop control circuit in response to the velocity checking signal, so that the rotation of the servomotor is immediately discontinued.
