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.
A method of measuring at least one dimension of a non-toothed tool using a tool measurement apparatus comprising a transmitter and a receiver, the transmitter generating a beam of light that is directed towards the receiver, the receiver producing a received intensity signal related to the intensity of received light, the method comprising the steps of;
