In order to research a method with simple structure, high precision and low cost for automatically measuring axis roundness, the article redesigns the traditional V-shaped measuring system into automatic measuring system based on the practical application and measuring precision of the traditional V-shaped system. The article introduces the basis principle of V-shaped method, the structure of automatic V-shaped system and selection of its component. The automatic system can realize automatic measurement by following processes:computer controlling, direct current servo motor rotating measured axis, counting encoder calculating the angle of measured axis, measuring head automatically collecting measuring data, computer calculating the data and outputing measuring result. The cost of the whole equipment is less than a hundred thousand Yuan.
