[0023] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0024] The principle of three-point method error separation technology is as follows: figure 1 shown. The three sensors P0, P1, and P2 are installed at different positions on the circumference of the workpiece, and the angles between the three sensors are α and β respectively. It is required that the installation axes of the three sensors intersect at the center of the circle O, which is also the origin and origin of the coordinate system XOY. Rotate the center of the table. When measuring, the sensor is fixed, and the workpiece to be measured is driven by the rotary table to make a rotary motion. According to the output equation of the measurement results and the error separation equation of the three-point method, the roundness error of the workpiece and the rotation error of the rotary axis can be separated by using appropriate paramete...
