    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 numerical control apparatus which reduces a cycle time by executing the movement command of a next block without temporarily stopping the movement of a workpiece even if a skip signal is input. Upon receiving the skip signal SS output from a sensing device, a skip signal sensing device determines the present position of the workpiece, stores the position in a memory device and outputs a skip completion signal AS. Then, an acceleration/deceleration distribution device carries out pulse interpolation of a present block and outputs a distribution completion signal ES on the completion of the movement. Further, a preprocessing distribution device, having received the skip completion signal AS, determines an amount of movement of a next block from the present position of the workpiece and preprocesses the next block of the machining program. On receiving the distribution completion signal ES output from the acceleration/deceleration distribution device, the preprocessing distribution device outputs an interpolation pulse IP2 and moves the workpiece without interruption.

    摘要: A working route (21) of a main shaft is divided into a plurality of measurement points, and a length from a center (24) of a complete round (20) to the working route (21) of the main shaft at each of the measurement points is measured, and this measured value is compared with a radial length of the complete round (20) to operate a deviation amount (D1, D2) from the complete round (20) at each of the measurement points. This deviation amount (D1, D2) is transferred symmetrically about the complete round in a radial direction of the complete round (20) to find a transferred position (28, 28A). As correction values for correcting the deviation value (D1, D2), an X-axis incremental amount and a Y-axis incremental amount obtained from a difference in the transferred position between the respective measurement points, or an X-axis absolute value and a Y-axis absolute value of the transferred position at each of the measurement points are incorporated into an NC working program to perform complete round working according to the program.
