Carbide end mills with varying edge helix angles were used in the study. Statistical analysis was additionally performedfor selected machining conditions. In addition, modelling of selected roughness parameters on the end face for the AZ91D alloy was carriedout using artificial neural networks. Results have shown that the tool with ?s = 20° is more suitable for the finish milling of magnesium alloysbecause its use leads to a significant reduction in surface roughness parameters with increased cutting speed. Increased feed per tooth leadsto increased surface roughness parameters. Both radial and axial depth of cut has an insignificant effect on surface roughness parameters.It has been proven that finish milling is an effective finishing treatment for magnesium alloys. In addition, it was shown that artificial neuralnetworks are a good tool for the prediction of selected surface roughness parameters after finishing milling of the magnesium alloy AZ91DTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
