A coding system for elements of machine tools, particularly of the numerically controlled type, consisting of a "bar" code (14) applied to the element (10) to be coded, and read by a reading head (17) provided with a code detecting sensor (18) connected to a circuit for transforming the code into signals fed to utilization circuits (21, 26) which operate by comparing the read message with a set signal. |
