The double ballbar(DBB) is an instrument to measure roundness error of the machine tools. Traditionally, DBB used in vertical tool which has a spindle, so can be easily installed without additional jigs. But condition horizontal different. Because no jigs are needed for measurement. Not only differences using but also forming circular trajectory exist. Center stationary, not tool. trajectories two balls same kinds method that measurement effect comparing with presented.
