Description: |
| Claim:
In a data controlled machine tool, including a transfer mechanism for transferring a plurality of tool assemblies individually between a storage position and an operating position, a control system comprising: encoding means, individually associated with each tool assembly, for identifying said tool assembly in accordance with a predetermined digital code, said encoding means comprising a series of individual code elements, all of substantially similar dimensions and configuration but selected from two groups having different field-coupling properties, mounted on said tool assembly in predetermined alignment with each other; sensing means, located in close proximity to but. spaced from said storage position, for sensing said code elements without physical engagement therewith, said sensing means comprising a plurality of individual field-sensitive sensing elements each exhibiting substantially different electrical properties when in close proximity to but spaced from code elements of said two different groups; and an electrically actuated control circuit, coupled to said sensing means, for controlling operation of said transfer mechanism in response to predetermined changes in the electrical properties of said sensing elements. |
