Abstract

A device for determining a dimension of a tool having a cutting edge includes a first light source configured to emit light parallel to a first axis, an image sensor which is associatable with a second axis extending orthogonally to the image sensor and an analyzing unit. The first axis and the second axis are inclined relative to each other. The device is configured such that the light emitted from the first light source is reflectable by the cutting edge of the tool in such a way that light spots arranged in a line on the image sensor are generatable by the reflected light. The analyzing unit is configured to determine positions of the light spots. The dimension of the tool is determinable based on the positions of the light spots.
