DESARROLLO DE UN INSTRUMENTO TELESCÓPICO DE ALTA PRECISIÓN BASADO EN MULTILATERACIÓN LÁSER SIMULTÁNEA PARA VERIFICACIÓN DE SISTEMAS PRODUCTIVOS
Modern manufacturing technologies demand high efficiency and precision in machining, handling, and measurement processes. The gradual implementation of open-architecture control programs in a new generation of Machine Tools (MT) allows for the compensation of geometric errors identified through volumetric verification, significantly enhancing machine precision.
While traditional verification focused on individual axes, the push for high-precision components—both in large-scale and micro-manufacturing—has led to the adoption of Laser Tracker (LT) volumetric verification. This technique characterizes the MT’s behavior across its entire working volume in less time, providing a global compensation for the combined effect of all geometric errors.
The primary objective of this project is the design and development of a high-precision telescopic system composed of three or more arms, based on simultaneous laser multilateration. By capturing distance data from all arms concurrently, the system leverages the superior accuracy of laser interferometry while maintaining the flexibility and process speed of an LT. This autonomous tracking system—following a sphere attached to the MT head—is designed for the verification of small to large-scale machine tools, Coordinate Measuring Machines (CMMs), articulated arms, and industrial robots.
