“…Umetsu et al [19] developed a new laser-tracking system to measure 21 parametric errors. LaserTRACER [20][21][22], a commercial instrument, was employed to analyze 21 parametric errors. The laser tracking system and LaserTRACER had to be set up at four spatial positions during the measurement.…”

Recently, a four-axis coordinate measuring machine, which consists of three linear axes and a single rotary axis, has been more widely used than a traditional three-axis coordinate measuring machine. The volumetric error influences the accuracy of the four-axis coordinate measuring machine. 27 parametric errors contribute to the volumetric error. This study proposes a new methodology to analyze the parametric and volumetric error of the four-axis coordinate measuring machine using a hole plate. First, the hole plate setup sequentially in three different planes. We measured the hole plate by using five different styluses. Second, 27 parametric errors were analyzed using the coordinate deviations. The volumetric error was constructed using the homogeneous transform matrixes. The volumetric error ranges were from 0.35 µm to 1.55 µm and from 0.35 µm to 2.83 µm without and with the single rotary axis. Third, three commercial instruments, namely a laser interferometer, an autocollimator, and a polygon-autocollimator, were used to validate the proposed methodology to verify the measured parametric errors. The absolute maximum differences, compared with the laser interferometer for three parametric positioning errors and the autocollimator for six parametric rotational errors for the three linear axes, were 0.56 µm and 0.54", respectively. Moreover, the absolute maximum difference of one parametric positioning error for the single rotary axis, comparing with the polygon-autocollimator, was 0.75". The En-values were 0.27, 0.54, and 0.27, respectively. The results demonstrate the proposed methodology's effectiveness and reliability to the industry's four-axis coordinate measuring machines.

“…It is possible to exclude the human influence in some measurement tasks, such as verification tests of machines and industrial equipment. Although the classic laser interferometer is still the most commonly used solution in such situations [9,14], there are laser tracking systems capable of performing the accuracy tests of industrial equipment with similar accuracies [3,4].…”

Laser Tracking systems are commonly used in all branches of industry, which requires accurate large-scale measurements for instance aviation, space and shipbuilding industries. Laser Trackers belong to the group of non-Cartesian Coordinate Measuring Systems. Determination of the measured point coordinates involves the measurements of distance using laser beam and two angles recorded by horizontal and vertical encoders. Additionally, the environmental conditions are monitored and used for compensation of measured distance. The coordinates of single measured point are estimated using the results obtained from a series of samples taken in a short time period. The average value obtained from a sample is given as a result; additionally, the dispersion parameters are calculated which can be used to evaluate the probing process. This paper presents the research procedure which allows assessing the influence of chosen dispersion parameter related to the sample averaging on accuracy of the measurements performed with laser tracking devices. The procedure involves standard elements measurements during which the points with similar level of RMS parameter are used for the calculation of the measurement result. Such approach allows simulating the increasing dispersion of points taken into account during sample probing. The results presented in the article can be helpful to the operators of laser tracking systems to assess the influence of the probing process on the measurement accuracy.

In case of coordinate machines that use CAA correction matrix, the issue of kinematic errors analysis may be based on the determination of residual error distribution. Temperature changes have an impact on CMM kinematic structure, which may cause the differences in the map of residual errors. As for today, the residual errors were analysed only for the reference temperature. No research was undertaken on the residual errors changes depending on the temperature variations. This paper presents the experiment aimed at residual errors analysis and resulting errors distributions for different temperatures.
