Abstract: In order to support setting in post-processor development, internal information of a numerical controller is acquired, a basic function usable by the numerical controller is extracted based on system information or parameter information, which is the acquired internal information, and the extracted function is output to a post-processor as a configuration file. The post-processor creates a machining program for the numerical controller by referring to the function set in the configuration file.

Abstract: A numerical controller has a first axis (reference axis) and a second axis (superimposed axis), and performs superimposed control which superimposes a movement amount of the reference axis on a movement amount of the superimposed axis, and thereby controls the movement of the superimposed axis. The numerical controller controls an acceleration start time of the axis to be accelerated, in a superimposition interval in which the reference axis is accelerated and the superimposed axis is decelerated (or reference axis is decelerated and superimposed axis is accelerated). After the axis to be decelerated is sufficiently decelerated, the axis to be accelerated is accelerated, and a moving speed of the superimposed axis does not exceed a speed limit of a machine in an acceleration/deceleration interval.

Abstract: A numerical controller controlling a machine tool calculates a number of incisions to a thread on the basis of an incision start position in a feed axis direction and an incision start position in a direction of an incision axis of a thread which are measured in a state in which a workpiece (a thread in the process of machining) is attached to a chuck of the machine tool, calculates an amount of phase deviation of a screw thread caused by reattachment of the workpiece on the basis of the calculated number of incisions, and re-machines the thread by positioning the workpiece and the tool while taking into consideration of the amount of phase deviation.
