“…Precision vertical angle measurements are indispensable in precision engineering, surveying technology, military industry, and scientific research fields. A range of vertical angle sensors and instruments, including electronic levels, inclinometers, theodolites, and total stations, are employed for this purpose [1][2][3][4][5][6][7][8][9]. Proper calibration of these sensors and instruments is crucial to ensure high reliability and improve measurement accuracy [10][11][12][13][14].…”

“…Various vertical angle sensors have been proposed based on optical or electrical measuring principles, with implementations also seen in micro-electromechanical system [1][2][3][4][5]. Common vertical angle sensors, such as electronic levels or inclinometers, find widespread use in measuring the straightness of precision linear guides, translation stages, and the flatness of surface plates [6,7]. Total stations and laser trackers are effectively applied in large-scale dimensional metrology, as they can measure the position of a reflective target in threedimensional (3D) space by combing single-axis translational position with two-axis angular positions [8].…”

A versatile measurement system was developed for efficient calibration of vertical angle sensors or instruments. The vertical angle measurement system (VAMS) comprises a precision rotation stage, a controller, and additional components for fixing an angle sensor or detecting angular deviation. It can generate single-axis rotation within ±120° range with a resolution of 0.01”. To detect angular deviation in angle instrument calibration, a special miniature autocollimator was developed using a diffractive optical element, providing high-precision angle measurement even with the short focal length of its lens. The performance of the VAMS was evaluated by comparing face angles of two optical polygons, measured by the VAMS and other reference systems. As typical exemplary calibrations, an electronic level and vertical angle readouts of a total station were calibrated with expanded uncertainty (k = 2) of 0.19” and 0.51”, respectively.

“…In order to miniaturize the size of the precision level, many novel measurement principles have been proposed. Using gravity as a reference, Ueda [15] proposed a high-precision micro capacitive inclination sensor, and Shimizu [16] proposed a roll error measurement system made by combining two micro capacitive inclination sensors to eliminate the influence of external disturbance. However, the accuracy and resolution of capacitive inclinometers are larger than 1 arc-sec.…”

An Innovative Dual-Axis Precision Level Based on Light Transmission and Refraction for Angle Measurement

Currently, the widely used pendulum-type precision level cannot be miniaturized because reducing the size of the pendulum will reduce its displacement so as to decrease the measurement accuracy and resolution. Moreover, the commercial pendulum-type level can only sense one direction. In this paper, an innovative compact and high-accuracy dual-axis precision level is proposed. Based on the optical principle of light refraction and the reference of the invariant liquid level, the pendulum is no more needed. In addition, based on the light transmission design, there is no reflection signal to interfere with the true signal. Therefore, the level can achieve a high accuracy and small-sized design. The calibration result shows the error of the proposed precision level is better than ±0.6 arc-sec in the measurement range of ±100 arc-sec, and better than ±5 arc-sec in the full measurement range of ±800 arc-sec.

“…Al-Bender et al [17] studied the interaction between a friction force and normal load in the pre-sliding zone of a contact surface of a rolling linear guide pair, established a calculation model of tangential force in the pre-sliding zone of the contact surface, and obtained the traction force by a numerical method. Yuki et al [18] proposed a new method for measurement of the roll error motion of a slide table in a precision linear slide. The proposed method utilizes a pair of clinometers in the production process of the precision linear slide, and the roll error motion measurement is carried out repeatedly, to confirm whether the surface form errors of the slide guideways in the linear slide are sufficiently corrected by a hand scraping process.…”

By studying the effects of geometric precision on kinematic accuracy, an error mapping model has been established, based on the hypothesis that a motion pair and its installation surface are rigid. However, when using this assumption, there is a significant error induced in high-precision computer numerical control (CNC) machine tools as compared with reality. One of the most important reasons for this error is failing to consider the error averaging effect of motion pair elements. Therefore, this work examines a high-precision horizontal machining center as its research object, and analyzes the error averaging mechanism of a rolling guide pair under a deformation of the rolling elements. The carriage bearing forces caused by guideway straightness errors are obtained by constructing a geometric error model of a single carriage. The relationship between guideway straightness errors and carriage bearing forces is described by a transfer function in the spatial frequency domain, and its characteristics are analyzed. It quantifies the so-called error averaging effect of the rolling guide system and, on this basis, a static model for four carriages is established to reflect the error averaging effect of the rolling guide pair on the position and orientation errors of the motion pair. In addition, it is found that the wavelengths and phase differences of guideway errors affect this error averaging mechanism, but the amplitude and preload have little influence thereon. The experiment result shows that the kinematic straightness errors in the x-and y-directions were approximately 1/3 to 1/2 of the guideway straightness errors in the corresponding directions. The results can be used to guide the precision design and assembly of machine tools. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
