“…For example, Ma Yu-zhen [ 17 ] introduced a spindle roundness measurement method based on a capacitive scanning system that uses three capacitive displacement probes to eliminate spindle errors through averaging effects, thereby achieving roundness error separation and confirming the effectiveness of the measurement system. Bin Duan [ 18 ] proposed a novel roundness measurement method based on single-probe scanning that simplifies mathematical processing without requiring complex forward and backward Fourier transforms. Through simulation analysis, the method’s feasibility and repeatability were verified, and the roundness measurement’s accuracy was significantly improved.…”

To investigate the high-accuracy roundness metrology of a needle roller 1.5 mm in diameter and 5.8 mm in length using the stitching linear scan method, a ruby ball stylus with a tip radius of 150 μm and a diamond stylus with a tip radius of 2 μm were employed to perform experiments under the same conditions. The precision coordinate data, derived from the needle roller’s cross-sectional circumference, were segmented into uniform eighths, each scanned with the stylus of a roughness measuring machine. The roundness profile of the needle roller was obtained by stitching the arc profiles, which were characterized according to the precision coordinate data of the arcs. The cross-correlation function, Euclidean distance, residual sum of squares, position error, and curvature of the measured arcs were used to evaluate the results, which can reflect the performance of the stylus. A comparison of the results obtained using the ruby ball stylus versus the diamond stylus demonstrates the ruby ball stylus’ greater suitability for use in the roundness metrology of the needle roller bearing examined in this paper.

“…In ultra-precision machining, Chen et al [12] designed an on-machine measurement device based on a chromatic confocal sensor to inspect workpiece surfaces with larger slopes and depths. In measuring the form and position tolerances, the measurement methods based on laser sensors are proposed to measure the roundness and rotation errors of a rotor [13,14]. Moreover, the laser sensor was used to build the on-machine measurement system for the geometric parameters of shaft part [15,16].…”

Wheel profile form directly affects the dynamic behaviour of rail vehicles. Moreover, it is an important factor to ensure the safe running of a high–speed vehicle. As off–line measurements do not provide high–efficiency and high–accuracy wheel profile measurements, we focused on on–machine measurement and evaluation for obtaining the wheel profiles of a rail vehicle in this study. By combining the wheel machining with the wheel measurement, the measurement and evaluation of radial and axial wheel profiles on the underfloor wheelset lathe were proposed. The measurement of radial wheel profile based on two laser sensors was introduced, and the corresponding error models of on–machine measurement were established. The error models were used to separate the measurement errors from the measurement data. This can improve the accuracy of measuring the radial wheel profile effectively. For measuring the axial wheel profile, an adaptive correction method of profile error was proposed to suppress the measurement error, which was the basis for obtaining an accurate equivalent conicity. By measuring radial and axial wheel profiles, polygonisation evaluation and equivalent conicity were obtained to evaluate the radial and axial dynamic behaviours of a wheelset, respectively. Finally, the measurements were applied to an underfloor wheelset lathe to verify the effectiveness of measuring wheel profiles. In this study, we not only improved working efficiency for the machine tools, but also provided a high–accuracy measurement method for the wheel profiles of rail vehicle.

“…Duan proposes a single-probe scanning method to fulfill the functions of multi-probe system. Because Fourier transform is not needed, the problem of harmonic suppression is avoided, but only one direction component of the spindle error can be separated [23]. The harmonic order of harmonic suppression can be changed by selecting the appropriate sensor installation angle or increasing the number of sensors, but it cannot be completely avoided.…”

This study focuses on the development of a spindle radial error motion separation method that can realize on-line measurement in the cutting state of the machine tool. Measuring the radial error motion of the spindle in the cutting process is an important basis for monitoring the machining quality of the workpiece and analyzing the dynamic characteristics of the spindle. The problems encountered in the application of traditional methods under cutting conditions, such as inaccurate data interception, angle non-uniformity of sampling data and installation angle error, are simulated and analyzed. An on-line measurement method based on the built-in encoder signal of the spindle is proposed. The angle signal of the spindle encoder is obtained synchronously by the built-in sensor acquisition technology of the CNC machine tool as the reference for data interception and calculation. The equal angle interval resampling method is constructed to convert the equal time interval data into the equal angle interval data, and the influence of the angle non-uniformity of the data on the measurement is weakened. The simulation comparison shows that the proposed method can effectively solve the problems existing in the measurement under cutting conditions. Finally, an actual cutting experiment is carried out to verify the effectiveness of the proposed method, and it is shown that the proposed method can obtain higher measurement accuracy than the traditional three-point method under cutting conditions.
