Abstract
Friction force and viscous resistance are yielded between driving parts of NC machine tools, and are changed by characteristic changes such as the change of lubrication conditions of driving components. Therefore, these affect the parameters for motion compensators. In this study, repeatability of quadrant glitches of feed drive systems was investigated. It is found from the results that height of quadrant glitch is changed by the friction force changes. In order to compensate the quadrant glitches repeatedly, torque-follow compensator was proposed. Corresponding to the friction force changes, the torque-follow compensator which compensates the difference between an ideal torque and an actual torque was newly developed. In this study, circular motion was simulated and measured with the compensator. It was confirmed that the proposed compensator can compensate the quadrant glitches repeatedly despite the friction force changes.
