Provided is an inspection system for a wire electrical discharge machine, capable of automatically performing inspection of a constituent element and the like. The inspection system for a wire electrical discharge machine is provided with the wire electrical discharge machine, a robot for inspecting the constituent element of the wire electrical discharge machine, an image pickup device provided on a movable part of tee robot and configured to image the constituent element, an image processing unit configured to acquire an image of the constituent element by means of the image pickup device, and a maintenance necessity determination unit configured to determine the necessity of maintenance of the constituent element based on the image acquired by the image processing unit.

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.
