<p>A tool of a metal-cutting machine provided with numerical control has an information data carrier for storing various data of tool characteristics such as the length, diameter, service life and other parameters of the tool. The data carrier is formed by an electrically erasable programmable read-only memory which has a large storage capacity. The memory is rigidly inserted in the tool or tool holder and is protected against damage and contamination. Inadvertent release and loss of the data carrier are avoided.</p> |
