Process optimization and crack detection using QASS Optimizer4D both work on the basis analysing structure-borne sound. Optimizer4D displays the production process in a three-dimensional diagram with the axes time (x), frequency (z), and amplitude (y).
The measuring device has to be adjusted to the respective production process. Cracks are easily and automatically detected in the 3D diagram due to their characteristic form. Furthermore, the qualification of other process parameters is possible. To achieve this it is recommended to reset the device to the desired condition of the process. Deviations can later be detected automatically with crack detection or pattern recognition. The set-up of the desired condition is required. Example: An inductor at an induction hardening machine is supposed to be monitored. The inductor delivers a steady frequency band at roughly 32 kHz. When there are deviations in frequency or amplitude, the Optimizer4D gives a warning signal as soon as the threshold values are exceeded or fall below the limit. This operating principle can be transferred to many different industrial production processes.
