    摘要: A method and apparatus for controlling the feed speed of a machine in a numerical control system having a manual pulse generator for generating pulses in response to a manual operation. The numerical control system numerically controls the machine by supplying the machine with the generated pulses as feed pulses in a manual feed mode and with feed pulses corresponding to a commanded feed speed in modes other than the manual feed mode. The commanded feed speed is modified in accordance with an override quantity stored in a register. The method includes selectively designating the modes other than the manual feed mode, changing the override quantity, which is stored in the register, based on the pulses generated by the manual pulse generator and in accordance with the designated mode, and modifying the commanded feed speed in accordance with the override quantity stored in the register.

    摘要: A method and apparatus for deleting a file from a bubble cassette memory. A file, constituting one input unit of data to be written into the cassette memory, is divided into a plurality of blocks each comprising a predetermined number of bytes and is thereafter stored in the cassette memory. In similar fashion a plurality of such files are stored in the cassette memory in numerical order. When a command for deletion of the n-th file F.sub.n is generated, files which were originally stored in the cassette memory following the n-th file F.sub.n are stored successively and in block-by-block fashion in the cassette memory starting from the position at which the n-th file F.sub.n was originally stored.
