SHAPING TECHNOLOGY

Rogov V. A., Gorbani S. — Use of Taguchi method for vibration and machined surface roughness optimization when machining

This article aims at optimizing cutting conditions in order to reduce the surface roughness (Ra) and vibration during turning of aluminum alloy AA2024. Machining process wos performed at lathe 16K20VF1 model, using standard cutting tool and cutting tool filled up with epoxy granite in toolholder made of hardened steel AIS1 5140. Spindle speed, feed rate, depth of cut and tool overhang werechosen as variable parameters. Turning operation and optimization ofsurface roughness and vibration were performed using Taguchi method L9 orthogonal array. Optimum cutting conditions and the influence of each parameter on the surface roughness and vibration were defined using the signal/noise ratio and analysis of variance. Spindle speed and tool overhang have the greatest influence on the surface roughness and vibration, respectively for both cutting tools. However, the optimum cutting conditions were determined in different levels. In addition, confirmation experiments were performed in order to verify the effectiveness and efficiency of Taguchimethod in optimizing cutting conditions.
Key words: surface roughness, vibration, cutting condition, optimization, Taguchi method
