A machine tool includes: an imaging unit for capturing an image of a tool from a side of the tool; a shape extraction unit for extracting the shape of the tool from the image of the tool captured by the imaging unit; a wear detection unit for detecting the degree of wear of the tool based on the shape of the tool; and a changing unit for changing at least one of the pitch and the depth of cut according to the degree of wear.

A universal machining system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely, and a tool turret capable of holding a variety of socketed tools. System also comprises a measurement sensor, which may be separate or comprise one of the socketed tools. A control program collects machining instructions for a series of workpieces, and directs the chuck, the tool turret, the measurement sensor, and at least one robot to load/unload workpieces and tools from the chuck and turret, respectively, measure workpieces and tools for quality control, and track available storage, overriding or skipping individual machining instructions as dictated by safety parameters and the availability of raw materials and tools.

A machine tool includes a workpiece holder, a tool holder holding working tools that includes a hob cutter used in a rough machining and a skiving cutter used in a finish machining, a tool magazine, a tool replacing device replacing one of the working tools mounted on the tool holder with the other of working tools housed in the tool magazine, a rough machining controlling section performing the rough machining on the workpiece, a tool measuring device measuring a position of a blade in a rotation direction of the skiving cutter, an angle correcting section correcting a rotation angle of the skiving cutter based on a result measured by the tool measuring device, and placing a tooth space formed in the workpiece and an edge tip of the blade in a position corresponding to each other, and a finish machining controlling section by which workpiece is finish machined.
