A wear amount measuring device includes: a light emitting unit configured to emit light on an object to be measured having a wear surface; an imaging unit configured to obtain an image of the object; and a calculation unit configured to calculate a wear amount by specifying a wear surface of the object from the obtained image. A positional relationship between the light emitting unit, the imaging unit, and the object is set such that, when a dummy object to be measured having a wear surface is arranged in place of the object, the light emitting unit and the imaging unit have a specular reflection relationship relative to the wear surface of the dummy object. The calculation unit calculates the wear amount by specifying the wear surface based on a difference in brightness of the image.

An improved method is described for measuring a dimension (e.g. diameter) of a non-toothed tool, for example a grinding tool such as a diamond coated burr. The method may be implemented on a machine tool, such as a lathe, machining centre or the like. The method comprises passing a beam of light from a transmitter to a receiver. The receiver produces a received intensity signal related to the intensity of received light. Analysis of variations in the received intensity signal is performed when a rotating tool is moved relative to the light beam to enable a dimension of the tool to be measured. In particular, it may be determined when the received intensity signal has crossed a threshold for at least a defined duration, the defined duration being less than the time taken for one complete rotation of the tool.

An accumulated wear amount calculation section calculates a wear amount of a blade edge of a punch and a wear amount of a blade edge of a die when a tool set of the punch and the die has processed a sheet metal once. The accumulated wear amount calculation section calculates an accumulated wear amount of the blade edge of the punch and an accumulated wear amount of the blade edge of the die by accumulating wear amounts of respective times when the tool set has processed the sheet metal multiple times. A tool management information managing section manages a state of the blade edge of each punch and each die by causing a tool management information storage section to store tool management information associating a tool identification code given to each punch and each die with the accumulated wear amounts calculated by the accumulated wear amount calculation section.
