20.500.12556/RUL-145168 Impacts of burnishing variables on the quality indicators in a single diamond burnishing operation Vpliv parametrov obdelave na kazalnike kakovosti pri finem poliranju z enim diamantom Diamond burnishing is an effective solution to finish a surface. The purpose of the current work is to optimize parameter inputs, including the spindle speed (S), depth of penetration (D), feed rate (f), and diameter of tool-tip (DT) for improving the Vickers hardness (VH) and decreasing the average roughness (Ra) of a new diamond burnishing process. A set of burnishing experiments is executed under a new cooling lubrication system comprising the minimum quantity lubrication and double vortex tubes. The Bayesian regularized feed-forward neural network (BRFFNN) models of the performances are proposed in terms of the inputs. The criteria importance through the inter-criteria correlation (CRITIC) method and non-dominated sorting genetic algorithm based on the grid partitioning (NSGA-G) are applied to compute the weights of responses and find optimality. The optimal outcomes of the S, D, f, and DT were 370 rpm, 0.10 mm, 0.04 mm/rev, and 8 mm, respectively. The improvements in the Ra and VH were 40.7 % and 7.6 %, respectively, as compared to the original parameters. An effective approach combining the BRFFNN, CRITIC, and NSGA-G can be widely utilized to deal with complicated optimization problems. The optimizing results can be employed to enhance the surface properties of the burnished surface. single diamond burnishing average roughness bayesian regularization vickers hardness NSGA-G fino poliranje z enim diamantom povprečna hrapavost trdota po Vickersu Bayesova regularizacija NSGA-G umetne nevronske mreže optimumi true false true Angleški jezik Slovenski jezik Članek v reviji 2023-04-12 08:59:32 2023-04-12 08:59:37 2023-04-13 03:31:25 0000-00-00 00:00:00 2023 0 0 Str. 155-168 no. 3/4 Vol. 69 Mar./Apr. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.9 0039-2480 10.5545/sv-jme.2022.303 148484355 Le_,_Van,_Nguyen_-_Impacts_of_Burnishing_Variables_on_the_Quality_Indicators_in_a_Single_Diamond_Burnishing_Operation.pdf Le_,_Van,_Nguyen_-_Impacts_of_Burnishing_Variables_on_the_Quality_Indicators_in_a_Single_Diamond_Burnishing_Operation.pdf 1 C48CA371CFE2D928402F13BC45565BF5 d34af83beba81dc3d78be7819c2f1c6dc07050bccf05f874706bcca15455f0c7 9e88d9bc-d8ff-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167857 https://www.sv-jme.eu/sl/article/impacts-of-burnishing-variables-on-the-quality-indicators-in-a-single-diamond-burnishing-operation/ 1 73f7dc2e-d8ff-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167856 Fakulteta za strojništvo Strojniški vestnik 0 0 0
