[Prior Art] =1 (4) For the accuracy correction of the three-dimensional coordinate measuring machine, etc., the type of the instrument is measured by a high-precision instrument: 丄 XI = calibration work. The instruments used usually include a zero-level flat ruler#. 3 The advantages of the photoelectric collimator, the inductance micrometer, the square ruler and the I ^ ° k method are that the calibration result is high in accuracy and reliable, and the disc is also flawed, and the disadvantage is that the amount of sin is working on the time #-, 1 The requirements of the people are higher, the phase is a J, the majority of the coordinate measuring machine users, the instrument $ measuring machine standard 1 amount, the calibration work, it is done by using the seat or the cone to complete the correction Work η:, step gauge, ball end rod, ball phase in the use of the general user ~ fast, more than the material is working in line with the international standard 6 200912248 IS0010360-2 specifications; and the calibration results are reliable, accurate Write 1*, manufacturing requirements, high and to ensure that the correction of the square dog each right page I often carry out identification tests. The above two positive methods have their own advantages, but they are inconvenient, and _ - our shortcomings are that the calibration work is complicated and tens of thousands of things, and the equipment is too expensive, thus limiting the three (four) denier / positive cost 4 And the correction cost is a new calibration method and correction device for the current coordinate measuring machine calibration. The condition '正(四) needs to be researched.,. Realize the coordinate, reliable, convenient, fast and low-cost calibration work of the coordinate measuring machine.

A standard spacing is required as the standard quantity, and other surface precision measurement results can be obtained. The quasi-pitch is used by any two spheres. Please refer to the method shown in the third method for calibration to obtain high-precision standard spacing. It can also be combined with a standard gauge and a high-precision inductive micrometer to perform positive calibration. The center of the ball at the center of the standard ball is (10)_, and the ball plate (1) moves on the 3 3) according to the measurement principle of the second figure until the ball plate ( ) moves 400 _, and the space can be measured within 5 〇〇 Measurement error.
