The objective of the present invention is to provide a tool measuring system, a control method, and a program with which it is possible for a cutting tool to be measured easily. This tool measuring system is provided with: a tool measuring device; a tool moving unit; a tool measuring unit; a tool correcting unit for feeding back the measured tool length and tool diameter of the cutting tool to a tool diameter correction number and a diameter correction number of the cutting tool; and a program computing unit for computing the operations of the tool measuring device, the tool moving unit, the tool measuring unit, and the tool correcting unit as instructions operable by the machine tool from a one-line control program in order to instruct the machine tool.

A method, an apparatus and a processing center for autonomously measuring a tool or a complete tool, include a tool holder and a tool clamped in the tool holder. The autonomous measurement involves a type of the tool first being autonomously determined, a point on the tool that distinguishes the tool then being autonomously determined according to the type of the tool, functional geometries of the tool being autonomously measured starting from this point, and subsequently a cumulative geometry being autonomously ascertained for the tool from the measured functional geometries.
