A machine tool is provided with a main shaft configured to have a tool fitted to a distal end portion thereof, a tool magazine for holding a plurality of tools, a tool exchanging arm for exchanging tools between the tool magazine and the rotary main shaft, and a table for attaching a workpiece, wherein the machine tool machines the workpiece by causing the main shaft and the table to move relative to one another in accordance with a machining program, and wherein the machine tool: is provided with an image capturing device for capturing an image of the tool fitted to a tool holder, and an interference checking device which uses the machining program, and shape data relating to the workpiece, the tool, and the machine tool to simulate machining before machining is carried out, to check for the presence or absence of interference between at least the tool and the workpiece; and acquires the shape data relating to the tool from the interference checking device, generates a two-dimensional tool model from the acquired shape data relating to the tool, compares the two-dimensional tool model with an image of the tool captured by the image capturing device, and determines that the tool is invalid if an amount of displacement between the two-dimensional tool model and the image data is equal to or greater than a prescribed threshold.
A machine tool system, comprising a spindle configured such that a tool is mounted on a distal end part thereof, a tool magazine which holds a plurality of tools, a tool exchange arm which exchanges tools between the tool magazine and the rotating spindle, and a table to which a workpiece is attached, wherein the workpiece is machined by moving the spindle and the table relative to each other in accordance with a machining program, the machine tool system comprising:
A tool determining method for determining whether or not a valid tool is mounted on a tool magazine of a machine tool system comprising a rotary spindle configured such that a tool is mounted on a distal end part thereof, the tool magazine which holds a plurality of tools, a tool exchange arm which exchanges tools between the tool magazine and the rotary spindle, and a table on which a workpiece is attached, wherein the workpiece is machined by moving the spindle and the table relative to each other in accordance with a machining program to machine the workpiece, the tool determining method comprising the steps of:
