Abstract
A machine tool includes a tool that machines a workpiece while being contact with the workpiece, a state-quantity-data acquisition unit that acquires state quantity data of the workpiece and of the tool, a state-quantity-estimation-data calculation unit that calculates state quantity estimation data from a simulation model including a device dynamic characteristic model indicating a dynamic characteristic of the tool and a workpiece model indicating a target shape of the workpiece, and a machining-state calculation unit that calculates machining state data indicating a machining state of the workpiece based on the state quantity data and the state quantity estimation data.
Claims12
