Abstract

The influence of burnishing conditions on the burnishing force in the inclined roller burnishing method, which was developed by the authors, is investigated. The wear behaviors of non-coated and TiN- and Diamond-Like-Carbon-coated rollers and the effect of the coated roller on the inclined roller burnishing were also investigated. A round bar of carbon steel and an aluminum-based alloy were used as the workpiece material. The burnishing force was measured by a strain-gauge type 3-component dynamometer. The burnishing force component, which acts in the circumferential direction of the workpiece, increased with increasing inclination angle of the roller. Improvement of the tool life of the roller was obtained with a TiN-coated roller on which nitriding treatment of the base roller was performed prior to TiN coating. A satisfactory burnished surface was obtained by burnishing with the DLC-coated roller.
