摘要:A tolerance design method based on error averaging effect for hydrostatic guideways motion accuracy was proposed in this paper. Firstly, the motion accuracy analysis model was established by average the oil film thickness considering the wavelength, amplitude and phase parameters of guide rails. Then, the guide rails straightness errors were calculated according to the relationship between the motion error and guide rails geometric error parameters, which realize the tolerance design of hydrostatic guideways. Finally, the method was applied to the design of guide rails in open hydrostatic guideways, and the measured motion accuracy results verified the correctness of the method.
