“…1.c). The HPTI under study in this paper, its main parts and its working principle is explained in [8][9][10]. In order to obtain the absolute values of the distance between the spheres from the lectures of the interferometers integrated in the HPTI an initial adjustment of the telescopic arms is needed.…”

“…However, to measure the head position ({X, Y, Z} coordinates) of manufacturing systems, the use of laser interferometers requires a prior adjustment to a reference length, since they measure incrementally. This adjustment procedure of the measurement system introduces an error in the resulting 3D coordinates that depends on the environmental conditions and the material of the standard element used to materialize the reference length [9]. This paper analyzes the temperature effect in the adjustment process of the HPTI based on interferometry [8].…”

Verification systems are needed for periodic verification and calibration of robots and machine tools to maintain and increase their accuracy. One of the ways to verify the volumetric accuracy of a manufacturing system is to measure the position of its head (X, Y, Z coordinates) using measurement systems that provide these results with the appropriate precision. The laser interferometer provides results with accuracy levels suitable for robot and machine tool verification applications. However, to measure the head position of manufacturing systems (X, Y, Z coordinates), the use of laser interferometers requires a prior adjustment to a reference length, since they measure incrementally. This adjustment procedure of the measurement system introduces an error in the resulting head coordinates that depends on the environmental conditions and the material of the standard element used to materialize the reference length. This paper analyzes the temperature effect in the adjustment process and how temperature errors introduced in said process affect the head 3D coordinates calculation of the Manufacturing System under inspection.

“…Gillory et al [17] introduced a highly promising absolute multilaterationbased coordinate measurement system utilising a single ADM and four measuring heads, thereby mitigating the expense associated with the four TIs required for simultaneous multilateration. Brosed et al [18] suggested an alternative approach not based on TIs, employing a telescopic instrument for simultaneous laser multilateration.…”

Large machine tools are critically affected by ambient temperature fluctuations, impacting their performance and the quality of machined products. Addressing the challenge of accurately measuring thermal effects on machine structures, this study introduces the Machine Tool Integrated Inverse Multilateration method. This method offers a precise approach for assessing geometric error parameters throughout a machine’s working volume, featuring a low level of uncertainty and high speed suitable for effective temperature change monitoring. A significant innovation is found in the capability to automatically realise the volumetric error characterisation of medium- to large-sized machine tools at intervals of 40–60 min with a measurement uncertainty of 10 µm. This enables the detailed study of thermal errors which are generated due to variations in ambient temperature over extended periods. To validate the method, an extensive experimental campaign was conducted on a ZAYER Arion G™ large machine tool using a LEICA AT960™ laser tracker with four wide-angle retro-reflectors under natural workshop conditions. This research identified two key thermal scenarios, quasi-stationary and changing environments, providing valuable insights into how temperature variations influence machine behaviour. This novel method facilitates the optimization of machine tool operations and the improvement of product quality in industrial environments, marking a significant advancement in manufacturing metrology.
