A method used to calibrate a set of reference angle gage blocks is described. Only the equipment usually found in a dimensional metrology laboratory is used, such as autocollimators and a surface plate. Contrary to some other well-known methods, supplementary sets of angle gage blocks, a high precision dividing head or a rotary table are not needed. To benefit from the sensitivity and repeatability of the autocollimators, while eliminating their errors of accuracy, a null-balance method has been used.[Journal translation]

While evaluating the accuracy of high-precision machine tools, it is critical to reduce the error factors contributing to the measured results as much as possible. This study aims to evaluate both the error motions and geometric errors of the rotary axis without considering the influence of motion error of the linear axis. In this study, only the rotary axis is moved considering two different settings of a reference sphere, and the linear axes are not moved. The motion accuracy of the rotary axis is measured using the R-test device, both the error motions and geometric errors of the rotary axis are identified from the measurement results. Moreover, the identified geometric errors are verified for correctness via measurement with an intentional angular error. The results clarify that the proposed method can identify the error motions and geometric errors of a rotary axis correctly. The method proposed in this study can thus be effective for evaluating the motion accuracy of the rotary axis and can contribute to further improvement of the accuracy of the rotary table.

Standard Table

For calibrating an angular rotary table, either a high precision standard table or a laser interferometer and related optics are normally employed at high cost. This paper establishes a novel, simple and low cost technique to calibrate a 4-degrees-of-freedom errors of a rotary table (three angular motion errors and one displacement error) for a 360° full circle by employing one reference rotary table, one 1D grating and two 2D (2 dimensional) position-sensing-detectors. With this technique, no highly accurate reference table with good repeatability is needed. After two full circle tests, the 4 DOF errors of the target rotary table and the reference table can be calculated respectively. The angular uncertainty of the measurement system can be less than 1.5 arc sec, while the displacement uncertainty can be up to 1.5 μm.

Measuring Accuracy

In order to increase the precision of a high speed dynamic autocollimator, which uses quadrate detector, we propose a new method to compensate the residual measuring errors. For this purpose, a multi-tooth rotary table with precision of 0.2 seconds of arc is used to calibrate the autocollimator. From the calibration data, a polynomial interpolation compensation algorithm is used. As a result, the measuring accuracy is increased to the order of 0.8 seconds of arc and the sampling speed is not affected.
