A Three-Point Method is often used to measure the deviation form circularity of a workpiece. The deviation is measured based on a gage line or plane of a measuring equipment. And magnifying powers are determined in the gage angle. But it is too difficult to make the gage to measure the deviation by high magnifying powers. In this paper, a new method based on the three point method is studied theoritically and experimentally. The measuring equipment is made of styluses instead of a gage. So, magnifying powers are determined by the distance between two styluses. According to the results, the principle of the new method is approximately same as a standard method. And making the measuring equipment is much more easy comparing with a gage of a standard equipment. Therefore it is able to measure for long frequency range in higher magnifying powers.
