This is Crack Detection 2.0
With non-destructive and in-process quality control QASS has been setting the standard for highly accurate crack detection during straightening for years. Now we outperfomed ourselves with our new Optimizer4D. This system not only detects cracks in the very moment they occur, but it minimizes false reject rate.
What is Optimizer4D?
Optimizer4D is a measuring computer that automatically detects cracks that form inside the components during straightening or other production processes.
How does Optimizer4D work?
During straightening acoustic emission occurs: pressure waves that flow through material and machine. A developing crack sends out a broadband, impulse-like and high frequency acoustic emission signal. This signal is highly distinctive from the signals of a flawless component, which makes a mix-up practically impossible.
The measurement system
Optimizer4D is based on a Linux System. It works with a custom-build measurement hardware. The system utilises High Frequency Impulse Measurement (HFIM) to deliver an image of the straightening process.
The hardware picks up the acoustic emission and converts the signals with a fast Fourier transform. This allows the system to display the acoustic emissions in 3D – on the three axis: time, amplitude and frequency.
When it comes to crack detection for straightening of hardened steel shafts, QASS is the world market leader. The functionality of Optimizer4D is yet to be matched on a global scale. Real-time frequency analysis makes it possible to automatically distinguish real cracks from noise, because both kinds of acoustic emission show a unique pattern in the diagram typical for the Optimizer4D.
