“…It is proved that the relative displacement of the two vertical surfaces is only related to the distance of the detection line C relative to the datum surface, independent of the direction, and in line with the geometric relationship in the detection model in Figure 14. Based on the above analysis, the data in Figures 24 and 33 are substituted into Formulas (16) and (17) to obtain the calculated surface shape contours, as shown in Figure 34. It can be seen from Figure 34 that the calculated surface shape contour is different from the known surface shape contour, indicating that there exists a positional relation between the two surfaces.…”

The position error of two parallel surfaces is generally constrained by parallelism. However, as a range of change, it cannot represent the positional relation between two parallel surfaces. Large-scale equipment such as machine tools are complex and difficult to move. It is also an engineering problem to perform field measurements on it. To this end, a method of describing the positional relation between two horizontal parallel surfaces and two vertical parallel surfaces on-site is proposed in this paper, which is a novel kind of position error, enriching the form of parallel surface position error, and solves the inconvenience problem of large equipment position error measurement. The measurement mechanisms are designed, and the measurement principle is given. Firstly, the combined projection waveform of the measured surface can be obtained by the geometric relationship between the measurement mechanism and the measured surface. Secondly, an algorithm is studied to process the obtained waveform, and the combined projection curve of the measured surface is acquired. Then, under the condition of considering the shape contours of the two surfaces, an algorithm is developed to acquire the calculated shape contour of the measured surface. According to the difference between the calculated surface shape contour and the known shape contour of the measured surface, the positional relation of the two surfaces can be determined. Meanwhile, the mathematical models of algorithms are established, and the measurement experiments are carried out, and the algorithms are verified by the mutual measurement method of the two surfaces. The results show that this method can accurately obtain the positional relation of two horizontal parallel surfaces and two vertical parallel surfaces.

“…By compensating the measurement errors, the volume error in the machine tool workspace is reduced, which enables the machine to have a higher machining accuracy. Lee et al [13] designed two measuring modes with different tool lengths based on the DBB to measure parallelism errors between the spindle axis and the linear axis of a machine tool. This low-cost and easy-toperform method needs only one DBB and an adjusting fixture.…”

Measurement and compensation of the geometric errors can improve the machining accuracy of machine tool. However, measuring bar of the double ball bar (DBB) is not variable. In this paper, a novel measuring equipment based on telescopic ball bar with an indexing joint (IJ-TBB) is proposed for the geometric errors. Firstly, the basic structure and measuring principle of IJ-TBB are introduced. Then, the effect of structural errors of IJ-TBB on the measurement accuracy is studied. Next, the error amplification characteristic and measurement resolution of IJ-TBB are analyzed. Finally, an experiment was carried out to validate the accuracy of IJ-TBB. The results reveal that the IJ-TBB has a high precision and high efficiency. In addition, the measurement resolution of IJ-TBB can reach up to 0.03μm, which is much higher than DBB. It is valuable to extend the measurement range and improve the measurement accuracy of machine tool.
