An advanced technology for information storage on machined component surfaces by means of micro patterns and optical data read-out is presented. Existing procedures for the cutting of micro patterns during the turning process are substantially extended by introducing two-dimensional data arrays. A closed-loop control system enables the cutting of patterns depending on the rotation angle of the workpiece and therefore on the spatial relationship between the cutting edge and the surface. To allow the flexible use of this technology, no additional angular transducer is employed, but the internal angular signal of the machine tool control is utilised. It is demonstrated that established control methods such as phase-locked loops provide sufficient accuracy for stabilisation of the angular position estimation. The advantage of two-dimensionally aligned micro patterns is demonstrated in a novel optical data read-out method. In addition to increased data integrity, adapted image processing algorithms allow the reconstruction of the stored data using a single monochrome camera image of the surface. A novel FTS for milling operations is introduced, expanding gentelligent information storage towards face-milled components. The findings are a further step towards the shop floor application of this technology.
