    摘要： A numerically controlled machine tool which allows the automatic generation of a restoring program for carrying out processing required for the resumption of an NC machining program to resume the execution of the NC machining program after the execution of the NC machining program has been stopped and interrupt processing has been performed. Specifically, even for nesting programs, when the machining program is re-executed from where it had stopped after the execution of the machining program has stopped and the operator has performed optional interrupt processing, the stop-time and re-execution-time machine statuses are compared to automatically generate the restoring program so that the machine status may be returned to the stop-time status, whereby the operator can perform the resumption processing of the machining program without any restrictions.

    摘要： A numerical control unit for changing a cutting condition of a machine tool during machining of a workpiece. The numerical control unit includes a knowledge storage section for storing at least two rules for changing the cutting condition. At least one of the rules defines a rate at which movement of the machine tool is decelerated based on the position of the machine tool with respect to a corner of the workpiece. Other rules may define the rate at which movement of the machine tool is decelerated based on the shape of the corner of the workpiece being machined. Also, the other rules could be established based on the material of the tool or workpiece. The knowledge storage section further includes a rule description part and assessment functions. The numerical control unit further includes an inferring section for inferring the optimum value of the cutting condition on the basis of at least the rule or rules which define the rate at which movement of the machine tool is decelerated based on the position of the machine tool with respect to the corner of the workpiece. The numerical control unit then causes a workpiece to be machined in accordance with the cutting condition inferred by the inferring section.

    摘要： A workpiece is machined by a primary cutter such as on a lathe, in a primary machining mode, and then any workpiece portions left uncut by the primary cutter are machined by a compensation cutter in a compensation machining mode to thereby produce the desired final cut shape. To effect this cutting operation, data on the shape of the workpiece, the desired final cut shape, and the shape of the primary cutter are entered into an NC apparatus, and the uncut workpiece portions are computed based on data entered in the NC apparatus. A compensation cutter suitable for cutting off the computed uncut workpiece portions in the compensation machining mode is selected from a plurality of cutters, and data on the depth of cut and the clearance of the compensation cutter are set into the NC apparatus. Paths of travel of the compensation cutter as determined from the uncut workpiece portions, the depth of cut of the compensation cutter, and the clearance of the compensation cutter are computed in the NC apparatus. The uncut workpiece portions are then cut by the compensation cutter.

    摘要： In the movable shaft (32) constructed by a plurality of motion modules (31), since the moving command based on the machining program (1) in unit of the movable shaft like the prior art is converted into moving commands of the motion modules (31) to control this movable shaft (32), the machining can be executed if the machining for the movement of the movable shaft is defined like the machining program in the prior art. Also, assignment of a plurality of motion modules (31) to the movable shaft (32) can be set arbitrarily and then the pulse distribution to the movable shaft (32) is executed in response to this assignment. In addition, if the failure is caused in the motion module (31), such motion module (31) can be disconnected.

    摘要： A numerical control system for machining a workpiece including a reader for reading a machining control program for the workpiece, a control device for supplying a control signal to a machine tool for the workpiece, and a storage device disposed internal or external to the control device, for storing a conversion table for converting a first character string read from the program into a second character string representing a command. The control device operates in response to the reader reading the first character string to supply the control signal to the machine tool in accordance with the command of the second character string. The second character string may represent, e.g., a delete command or a repeat instruction command.
