“…The implementation of error compensation technology is an effective way besides design of machine tools to deal with deviations and accuracy degenerate that are caused by assembly, manufacturing and the operation of machine tool [7][8][9]. According to broad definition of error compensation technology, which consist of error modeling, error measurement and identification, and error compensation [10]. To improve the geometric accuracy of machine tool, the elimination strategies of geometric errors through kinematics modeling, measurement and identification should be given to precision machine tools.…”

“…Schwenke et al and Ibarali S reviewed measurement methodologies of multi-axis machine tool about identifying the value of geometric errors [30,31]. Based on these studies, geometric errors are characterized by these special measuring methods, such as laser interferometer measurement method [32,33], plane grating method [13], machine visual inspection method [34], artifact standard method [35], R-test measurement method [36], laser tracker measurement method [10,37], double ballbar (DBB) method [38], machining test method [39], and so on. However, some of these approaches are susceptible to range of measurement, such as DBB and plane grating method.…”

 Geometric error is the main obstacle that affects the quasi-static accuracy of horizontal boring machine tool. To improve quasi-static performance, the error terms that all PIGEs and PDGEs must be measurement and identified precisely. This study proposes a novel methodology for measuring and identifying that the above two types of geometric errors based on DBB for rotary axis. The error terms of linear axis are identified from measurement model based on exponential product method and a preset measure trajectory, and the measure coordinate system be unified together with reference coordinate to lower the uncertainty of identification accuracy, and then Elastic Net method and improved weight function IGG3-LTS method are established to identify the PIGEs and PDGEs of rotary and linear axes respectively. This method has the advantage that measurement with built in-sensors method that synchronously without interfering with the running state of the machine tool, and neither the inaccuracy of reference-frame misalignment nor installation error of the measuring instrument affects the geometric error identification results of linear axis. , the other is all PIGEs and PDGEs particular to rotary axis of horizontal boring machine tool are determinated accurately. The measurement and identify strategy is demonstrated by experimental comparison on a four-axis precision horizontal boring machine tool, the minimum compensation rate of each precision index of test specimen is 40.0%, the average compensation rate is 52.7%, and the maximum compensation rate is 62.5%. under the actual condition of machine tool.

The ballbar is currently the most widely used instrument for identifying and measuring rotary axis geometric errors, but the measurement results are unreliable due to measurement defects. So the geometric error measurement and uncertainty evaluation method based on ballbar is proposed. Firstly, the radial, tangential and axial measurement are carried out with the ballbar, and the geometric errors are identified according to the eccentricity and deviation of the trajectory. Then, by clarifying the mechanism of uncertainty caused by the tool setting error, ballbar installation error and translational axis error, the evaluation model is established. Finally, this study uses the Monte Carlo method to analyze the measurement uncertainty. The results show that the tool setting error and translational axis error are the main sources of measurement uncertainty, and the measurement uncertainty of the angular positioning error is the largest, which is contributed by the sine and cosine terms in the error identification equation.
