REVERSE-TECH s.r.o. specialises in industrial automation and delivers complete solutions for modernising and optimising industrial processes. Within the EDIH-DIGIMAT project a successful collaboration took place, focused on optimising the process of precise 3D measurement of an aluminium fixture.
The main business of REVERSE-TECH s.r.o. is the development and manufacture of single-purpose machines, precisely engineered to each customer's specific requirements so they perform their tasks within production lines efficiently. The company also focuses on test equipment (testers) that verifies the quality and reliability of manufactured products. Manipulators and robotic applications, which enable fully automated operation with high efficiency, are an integral part of its offering. The company also designs and builds automated production lines, and complements them with machine and equipment servicing.
The project responded to the need to increase the efficiency and accuracy of measurement processes, which play a key role in quality control and in validating finished products. The main goal of the collaboration was to cut the time measurement takes.
Two methods were tested, each combining laser tracker technology with a different tool. A laser tracker is a portable measuring device that uses a laser beam to determine the position of points in space precisely. The system sends a laser beam to a reflector placed on the measured object and measures the distance and angles, thereby determining the exact 3D position of the point. The second tool is the T-Probe, a wireless handheld probe that makes it possible to measure hard-to-reach or hidden points. Combined with the laser tracker it delivers high measurement accuracy over a range of up to 60 metres.
In terms of time, the laser tracker and scanner method proved the most efficient. Even so, the final choice of method depends on how complex the shape of the measured part is and on the operator's experience. The ideal answer is a combination of both methods, which allows flexible measurement of varied parts and optimises costs.
“The case study carried out with CEITEC VUT gave us a deeper insight into technologies for measuring precise fixtures, which until then had been limited to non-contact arms. Thanks to the technology used we received a complete 3D shape analysis, and deviations in accuracy can now be eliminated before handover to the customer.”
