20.500.12556/RUL-164005 Multi-response optimization of single point incremental forming of Al 6061 sheet through grey-based response surface methodology Večkriterijska optimizacija točkovnega inkrementalnega preoblikovanja pločevine iz materiala Al 6061 po metodi odzivnih površin za siv sistem The single point incremental forming process (SPIF) is materialized to form the desired shapes in low-cost sheet metal processing and well suited for low batch components and customized designs. Many modifications have been attempted in recent years to maximize the formability, geometric accuracy and quality of the SPIF formed parts. In this work, an attempt has been made to analyse the influence of process parameters namely ball tool diameter, step size, spindle speed and sheet thickness on final wall thickness, forming force and surface roughness. The optimized results exhibit the desirable formability when the roller ball tool diameter of the tool is 12 mm. The results also project that formability of the sheet metal is minimized when the spindle speed is increased and the ball diameter maximizes the accuracy and surface roughness. Also minimizing the step size increases the product quality features. Upon conducting this multi-response optimization by grey based response surface methodology (RSM) technique It is identified that 12 mm ball diameter of the tool, 0.25 mm step size, 2445 rpm spindle speed, and 2 mm sheet thickness are the obtained optimized SPIF process parameters as confirmed through confirmation experiments. grey based RMS single point incremental forming roller ball tool surface roughness točkovno inkrementalno preoblikovanje Al 6061 preoblikovalnost metoda odzivnih površin true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-15 13:20:59 2024-10-15 13:21:03 2024-10-16 04:09:06 0000-00-00 00:00:00 2024 0 0 Str. 507-514 no. 9/10 Vol. 70 Sept.-Oct. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.7 0039-2480 10.5545/sv-jme.2023.618 211618819 Multi-Response_Optimization_of_Single_Point_Incremental_....pdf Multi-Response_Optimization_of_Single_Point_Incremental_....pdf 1 03442591EBF66FE22C76795281BDA49A 6f779d42e8143200bdb5ef5644672ebaf200a8e9d879b26ca158efda9cdc4dc9 88c6ce40-8ae7-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194065 https://www.sv-jme.eu/sl/article/multi-response-optimization-of-single-point-incremental-forming-of-al-6061-sheet-through-grey-based-response-surface-methodology/ 1 55ea2947-8ae7-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194064 Fakulteta za strojništvo Strojniški vestnik 0 0 0
