PROBLEM TO BE SOLVED: To provide a numerical controller with machining curve creation function that performs machining by creating a cubic curve (a segment curve) corresponding to as many command points as possible, connecting a plurality of cubic curves (segment curves), creating a machining curve that is a curve for machining, interpolating the machining curve, and driving drive axes to the interpolated positions.SOLUTION: A command reading/analyzing unit 2 reads commands of a machining program and activates a machining curve creating unit 4. The machining curve creating unit 4 activates a segment curve creating unit 6, creates a single segment curve as a machining curve, and sets the segment curve to interpolation data. The segment curve (a part of the machining curve) set to the interpolation data is interpolated by the interpolating unit 8, and the respective drive axes (X, Y, and Z axes servos 10, 12, and 14) are driven to the interpolated positions. The creation of such segment curves, the setting of the segment curves to interpolation data, and the interpolation process thereof are repetitively and consecutively executed. |
