Abstract: To address the issues of ineffective compensation for aspheric machining figure errors, an XZB three-axis ultra-precision machining method was proposed. The impact of errors in tool alignment,tool radius and the deviation of tool tip relative to the B -axis rotation center on workpiece surface accuracy was analyzed, and the corresponding compensation methods were presented. Turning experiments of nickel-plated convex aspherical workpieces were conducted.Figure errors of the workpieces were reduceed from 0.6774μm to 0.0749μm ,with the XZB three-axis linked turning method. Experimental results show that the XZB three-axis linked turning process significantly improves the surface shape accuracy and surface quality of small-diameter aspherical surfaces, compared with the XZ two-axis linked turning method.
