Abstract
This paper aims to present different methods of volumetric verification in long range machine toll with lineal and rotary axes using a commercial laser tracker as measurement system. This method allows characterizing machine tool geometric errors depending on the kinematic of the machine and the work space available during the measurement time. The kinematic of the machine toll is affected by their geometric errors, which are different depending on the number and type of movement axes. Obtaining the transformation matrix that defined the kinematic of the machine tool, the measurement system, the rotation nominal matrix of the rotational axis, the relation between laser tracker and machine tool coordinates is obtained. The verification procedure and the characterization technique to use are determined by the available space during the measurement. The best combination of parameters, techniques and methods were obtained through the realization of a large number of synthetic tests based on not linear optimization techniques.
