Frequency Analysis of Motor Vibrations
To monitor the health status of a gear or machine, attocube’ s IDS3010 can be used to track machine vibrations. To improve the vibration behavior of a machine, its motor was rotated at different speed levels and the motor’ s vibrations were measured on the outer shell of the motor. Conducting a live Fast-Fourier-Transformation( FFT) showed that the motor rotating with 2000 rpm generated vibrations at 270 Hz which in turn amplified a system resonance at 345 Hz, and therefore drastically increased the overall vibration amplitude. At this system status, the vibrations amplitude was identified to be more than 150 nm, while the maximum acceptable amplitude was set to 100 nm. This crucial information enabled the system’ s manufacturer to minimize the system response to vibrations and prevented potential failure.

Highly Precise Micro Manufacturing
Ever increasing requirements for precision and size of machined parts have driven the development of highest-precision machining tools. The Square Foot Manufacturing concept separates well-known machining centers into small-sized sub-groups having standardized interfaces not only for power and data transmission but also for the transmission of processing forces and moments. Laser interferometry plays a key role in the piezo-based feed units of this concept as well as in the measurement of the reproducibility of these interfaces. A special differential technique allows for precise characterization of translational and rotational errors, which, in this case, are better than 0.16 μm and 8.22 arc seconds( 3 sigma) respectively.
