Reliability assessment of burnishing processing of aluminum alloy

The life and reliability of machine components or elements are affected greatly by the surface integrity. Machined surfaces by conventional processes such as turning and milling have inherent irregularities and defects like tool marks and scratches that cause energy dissipation (friction) and surface damage (wear). Burnishing processing is a kind of chip-less processing which improve the surface integrity obviously. To expand the application of the processing, the method of reliability assessment of burnishing processing was investigated theoretically and experimentally in this paper. The methodology was proposed with the probabilistic modeling and the experimental results. The reliability of two kinds of burnishing processing (rigid burnishing processing and elastic burnishing processing) were analyzed and compared with the methodology proposed.
