In this study, investigated are the relationships between machining accuracy and motion errors of the machine tool. Moreover a method of compensating for the relative motion errors between tool and workpiece has been developed and its capability for improving the form accuracy has been experimentally evaluated. Flatness of diamond turned surface can be analytically divided to circular flatness and radial straightness. The circular flatness is mainly influenced by motion errors of the work spindle, i.e. axial motion error and angular motion error. Because of high repeatability of the motion errors, the circular profile is dependent on the radius and the rotational angle. The radial straightness depends upon straightness of locus of the diamond tool or motion errors of the carriage. These relationships have been demonstrated by experiments. The method of compensation of relative motion errors between the tool and work was effective to improve the flatness. Surface roughness of the diamond turned surface was greater than theoretical surface roughness. The differences between the actual surface roughness and the theoretical one were due to inaccuracies in copying the tool profile, anisotropy of the work material and vibrations of the machine tool.
