Axis operation completion determination device and method for determining completion of axis operation

An axis operation completion determination device that determines, based on a machining program, completion of an axis operation of a machine tool which machines a workpiece by controlling at least one axis, the axis operation completion determination device comprising:

• an analysis unit that analyzes the machining program to generate an operation command for the axis;
• an execution control unit including an interpolation unit that manages execution of the operation command and to command an operation of the axis based on a result of analyzing the machining program, and an operation completion determination unit that determines that the operation of the axis has been completed;
• an axis control unit that generates a control command based on the operation command for the axis from the interpolation unit;
• and
• an axis operation simulation unit that simulates, based on the control command, feedback control using a servo control model and a plant model to calculate virtual responses of the operation of the axis,
• wherein the operation completion determination unit determines, based on the virtual responses, that the operation of the axis is complete.
