Abstract
A method for evaluating the error averaging effect of hydrostatic guides is proposed, which considers three-dimensional profile error of guides. Error averaging models for hydrostatic guides with single pad and double opposed pads are deduced, respectively. Results show that the error averaging effect is influenced by the profile error in both the width and length directions of hydrostatic guides. Additionally, the oil film stiffness plays an essential part in the error averaging effect when a hydrostatic guide is composed of opposed pads. Experimental results show the method is effective for predicting linear motion error caused by components profile error.
