Abstract: The numerical controller creates a machining path on which a wire electrode is moved by analyzing blocks of a machining program, and creates interpolation data indicating an amount of movement for each interpolation period on the machining path. Further, the numerical controller calculates a length of the wire electrode used for machining (machined surface length) for each interpolation period, calculates a consumption amount of the wire electrode for each interpolation period, calculates a compensation amount for compensating the amount of movement based on the interpolation data, on the basis of the calculated consumption amount and compensates the amount of movement indicated by the interpolation data, based on the calculated compensation amount.
