A new method and device for measuring motion errors of NC machine tools are proposed. The device consists of a plane two-link mechanism and two rotary encoders to measure the rotation angles of links. The working sphere of the device is a circle with a radius of double link length, except a small neighbourhood around the change points of the link mechanism in the center and circumference of the circle. Because the measuring method has a high resolution for any measured point in the working sphere, it is possible to measure most types of motion errors of NC machine tools, in particular, the error of the circular motion. The device is compact and its installation is simple and quick. The measuring tests show that the trial equipment has good response to a small displacement of about 1μm and the measuring results have high accuracy and good reproducibility. The influence of measuring noise is hardly observed in measuring results.
