Four methods aiming at measuring rotary machine axis center trace are discussed in detail.The comparative analysis is made on some aspects such as measurement accuracy, on-machine characteristics, feasibility, practical operation convenience and the integrity of measurement information.In order to simplify measurement, the axis profile error is ignored in traditional condition, while the measurement accuracy will be reduced.The 3-point method that the axis profile error is firstly separated has better real time character, at the same time, not only the axis motion error but also the axis profile error can be measured.All of those information can be used to diagnose the fault origin.The analysis result is proved to be correct by the experiment.
