Abstract:
This paper presents the role played by multilateration when laser trackers (LTs) are used in volumetric verification of long range machine tools.
A comprehensive study on the influence of LTs positioning has been done. The parameters taken into account during the positioning of the LTs are: the viewing angle, the distance to the work space and the LT measurement errors.
Also, different self-calibration techniques for calculating the LTs positioning are explained in order to show their influence in the correction improvement using multilateration techniques.
Finally, it is shown how obtained results improve the effectiveness of this procedure in terms of the final error correction when LTs are used in long range machine tool volumetric verification.
