| Research Abstract |
This study aims to improve positioning accuracy by frictional compensation using frictional model with several equations for positioning device with linear ball guide ways. Experiment of estimating parameters is carried out for modeling frictional behavior. As the result, the linear ball guide ways have strong nonlinearity in minute displacement like amplitude of 10nm. Moreover, the characteristic depending on feeding velocity of linear ball guide ways become clear.
