A method is proposed for measuring a surface of rotation using a cylindrical coordinate system and multiple measuring stands and a single rotary table. This method possesses lots of advantages such as high data collection efficiency, collision avoidance and high accuracy in form error measurement. The key techniques discussed in detail include the determination of stands' coordinate systems offsets with reference to the rotary table, the determination of the effective radii of the probing
