Verificación volumétrica inteligente de sistemas productivos mediante multilateración lÁser simultÁnea
This project focuses on enhancing the precision of production systems by analyzing and compensating for quasi-static and dynamic errors. While traditional geometric verification is often time-consuming, this research advances Volumetric Verification as an indirect measurement technique. By integrating laser interferometry—specifically through Laser Trackers (LT) and Laser Tracers (LC)—the project develops mathematical corrections for combined geometric and kinematic errors, significantly reducing verification downtime and the impact of external environmental factors.
A key innovation of this research is the development of simultaneous data capture strategies using three telescopic arms. This system evolves previous prototypes to perform efficient volumetric verification of rotary axes in Machine Tools (MT). By implementing simultaneous laser multilateration algorithms, the group aims to achieve high-precision tracking and error determination, bridging the gap between portable metrology flexibility and the extreme accuracy of laser interferometry.
Aligned with Industry 4.0 paradigms, the project extends these techniques to flexible robotic machining cells. The research incorporates complete joint-error models and direct measurement strategies using up to six simultaneous telescopic systems and reference spheres. To manage the inherent non-linearity of machining conditions, Machine Learning tools are utilized for error modeling and real-time correction. The final validation involves machining “master parts” to empirically demonstrate the reduction in volumetric error and the improvement in autonomous manufacturing precision.
