A cutting force of a cutting tool and wear of the cutting tool can be estimated. This estimation device is provided with: an NC program interpretation unit that interprets an NC program; a command generation unit that generates a command value by interpolating a command point on the basis of the NC program; a feedback control unit that causes the drive of a motor that drives the feed shaft and the main shaft to follow the command value; a mechanical configuration information unit that stores characteristic values indicating characteristics of at least one of the material to be cut, the cutting tool, and the motor; a cutting force estimation unit that estimates a cutting force in the cutting tool on the basis of the torque command and a characteristic value possessed by the mechanical configuration information unit; a matching unit that matches the time-series data of the estimated cutting force with the time-series data of the actually measured cutting force; a parameter optimization unit that calculates, on
