During simulation of kinematic calibration of virtual axis machine tool, indirect method is used for measuring its position and orientation; meanwhile Jacobean matrix regrouping method is used instead of arduous optimization to avoid measurement noise maginification. Simulation result shows that although all structural error of virtual axis machine tool can not be identified completely while the moving platform moves inside its working space, the moving platform kinematic accuracy is fulfilled inside the whole working space after error compensation. It shows that the method for calibration is feasible.
