Abstract
The present disclosure provides a machining simulation device capable of obtaining a machine-tool transfer function without requiring data collection and expert knowledge. The machining simulation device includes: a transmission characteristic generation unit that generates a transmission characteristic of a machine tool; and a simulation execution unit that simulates behavior of the machine tool by using the transmission characteristic. The transmission characteristic generation unit includes: a control information acquisition unit that acquires motor information and a control parameter of a motor control system of the machine tool; a motor characteristic calculation unit that calculates a motor characteristics based on the motor information; a control characteristic calculation unit that calculates a control characteristic of the motor control system on the basis of the control parameter; and a transmission characteristic calculation unit that calculates the transmission characteristic satisfying a predetermined requirement on the basis of the motor characteristic and the control characteristic.
