Contour/Outline Control in the blanking of Security KeysSpecial processing units are required for the manufac-ture of security keys. During the production process, a permanent change between the key blanks takes place. The company Aumat in Solingen specialises in the pro-duction of such keys. The processing units that are used to produce the key blanks rely on high-performance op-toNCDT 2200 series laser sensors from Micro-Epsilon.
During the inlet of the different key blanks, the individual processing data is loaded from a database. Prior to pro-duction, the unit verifies if the blank is appropriate for the data in the unit. Therefore, a laser sensor traverses in the opposite direction to the key blank in order to achieve a profile of the surface of the blank. If the profile corres-ponds to the reference data, the key blank is released to be processed further.
Reliable acquisition of data on shiny or matt metal sur-faces, as well as a high spatial resolution, is of critical im-portance to the customer. Due to operational speeds, a measuring rate of 10kHz is required. Furthermore, a large base distance is also important due to the mechanical design. Due to its reliable performance measurement, Aumat decided to apply the optoNCDT 2200 laser sensor with a 10mm measuring range. The sensor achieves the required measuring rate of 10kHz, while also offering ac-curate, reliable measurement data results due to an integ-rated real time surface compensation (RTSC) feature.
Advantages to the customer:- Excellent price-performance ratio- Complete surface detection of the blanks- Minimal spot size
Requirements of the measuring system:- 50µm measuring spot diameter- 3µm repeatability- 10,000 measuring results per second
