Burnishing process on al-alloy and optimization of surface roughness and surface hardness by fuzzy logic

In this study, Aluminum alloy (Al 7075 T6) has been burnished using different burnishing parameters (number of revolution, feed, number of passes, and pressure force) with burnishing apparatus. Following, burnishing parameters which affect to surface roughness and surface hardness on Al 7075 T6 materials have been discussed. Using the experimental results a fuzzy logic model has been used to achieve the best parameters for the burnishing process. The fuzzy model predictions suggest that the most suitable values for surface roughness are the pressure force of 200 N, and a feed of 0.1 mm/rev with two tool passes. These results, which obtained from the fuzzy model, are highly consistent with the experiments, (C) 2008 Elsevier Ltd. All rights reserved.
