Tube drawing operations can benefit greatly from preventing chatter and mitigating the human error in detecting it. Instead of waiting for the chatter to escalate and potentially damage your workpieces and tools, it’s best to detect chatter in its earliest stages and reduce drawing speed right away. COLD DRAWING’S INHERENT PROBLEM Exactly what is chatter,…
DetailsThe requirements of complex acoustic analyses have forced us early on to choose innovative and unique approaches in order to be able to measure successfully in harsh industrial environments Our standard measurement concepts have long proven themselves as world market leaders, but experience and reality show that standard cannot always be …
DetailsWe have just published our latest software release and can significantly improve our customer relations on the basis of the newly developed technologies. Especially projects that do not comply with the standard will benefit from the changes. The implementation of a QASS process monitoring system then runs in four phases.

Details“It is more than just an update, we are facing a new paradigm in software development and customer relations. The very special last few months have allowed us to complete many developments and create a whole new type of measuring device”.
DetailsMore and more assembly processes are being automated and carried out with pre-assembled components that are joined together to form assemblies. The connection of the assemblies often takes place inside, so that the process and the result cannot be checked by visual …
DetailsCrisis makes inventive, that could be the new guiding theme of Qass. We have taken advantage of the prescribed mandatory break to thoroughly refit our products and to break new ground in the process. In absolute consequence, completely new products have been …

DetailsQASS is the specialist for component evaluation, for process optimization, crack detection and tool monitoring. If it comes to crack detection during bending and straightening processes, QASS is the world market leader. Our new method of High-Frequency-Impulse-Measuring (HFIM) has set new standards.
Cognitive Measuring is interpretive measuring. Optimizer4D recognizes all by itself and in real-time, if a production process exceeds tolerance thresholds. QASS-systems analyze big amounts of sensory data, in real-time, and they identify hidden patterns.
The combination of cognitive measuring and high-frequency acoustic emission develops a new dimension of process data analysis. Formerly, many processes just delivered noise to a evaluation system. Now it’s possible to gain insights out of these noisy processes that describe the condition of tool and component. By this, machines can evaluate themselves and detect if the last process step was successful or not.
Faulty components generate a characteristic HFIM-pattern during the process. Optimizer4D is able to detect and to discharge these components automatically.
Find the optimum of speed and quality for machining processes: evaluate the edges of a machining tool in real-time and detect chatter marks or broken edges.
Since years, QASS defines the standard of high-precision Crack Detection, especially for straightening processes. Destruction-free quality evaluation of component and material is our expertise. With High-Frequency-Impulse-Measurement (HFIM), it’s easy to reliably detect cracks and to distinguish real cracks from (putative) false rejects.
Do you run your process with the highest possible speed? How far can you expand the maintenance interval of your machines before quality deteriorates? Optimizer4D can answer these questions.
“The wbk Institute of Production Science explores together with the IAM-WK Institute for Applied Materials of the Karlsruhe Institute of Technology the possibilities of monitoring machining, laser ablation and heat treatment processes, using the QASS Optimizer4D. The device is appreciated especially for it’s large measurement range and it’s real-time-capability, combined with easy handling. Together with QASS, we’re identifying and checking further fields of application.”

“The Optimizer4D enabled us to realize studies on cracks that appear during grinding, at which just macro-cracks were detected. Additionally, we did a research in order to reveal a possible connection between overheating while grinding and the HFIM-signal. We also did a comparison between forces and data from the HFIM-Signal. Besides we were able to detect the position of reinforcement wires inside of extruded aluminium bodies with the Optimizer4D. A corresponding online-analysis of the HFIM-signal empowered us to shut down the process and to expose the reinforcement wires. The Institute of Machining Technology (ISF) has used the Optimizer4D in a successful way during single grain scratch tests with diamond in concrete; also, the device was successfully used while lathing beta-titanium alloys.”

“Structure borne noise analysis allows to determine the ideal point of time for maintenance. During normal operation and incorrect operation different frequency bands were established. Plastic injection molding companies are able to evaluate the quality of their plastics products with HFIM.”
