A management method for a cutting tool of a machine tool is provided. A user host imports a graphical data of a workpiece and a cutting tool database into CAM, and a user may select cutting tools to establish a complete machining process. T codes are replaced with electronic tags. Before executing a machine code comprising the electronic tags, the machine tool re-scans the cutting tools assembled at a tool turret and updates cutting tool arrangement information to ensure that the tool turret is equipped with the cutting tools used in the machining process. When the machine tool stores the electronic tags, a ready message is displayed for reminding an operator. When the electronic tags are not stored, the current storage location of a cutting tool lacked in the machining process or a warning message is displayed at the operation interface for reminding the operator.

A tool management device includes a data storage unit for storing (i) tool information including a location of a tool and (ii) a tool-bench information including at least a correspondence between a machine tool and a tool bench, a tool management unit for changing data in the tool information, and a reception unit for receiving a detachment notification when a tool is detached from the machine tool. If the detachment notification is received, the tool management unit changes the location of the tool in the tool information from (a) the machine tool to (b) the tool bench corresponding to the machine tool in the tool-bench information.

A numerical controller performs control for changing a tool mounted on a spindle to another tool stored in a tool magazine based on a machining program. The numerical controller analyzes a command by a block of the machining program, predicts a time required for machining by the analyzed command, and selects a tool changeable before a tool change command, during tool selection, based on the predicted time.
