20.500.12556/RUL-166836 Experimental investigation on SS202 using tubular and double D tubular electrode tool in electrical discharge drilling machining To meet the demands of the manufacturing industry, a more robust approach is needed for current manufacturing processes. Machining of very hard materials with excellent dimensional accuracy and surface integrity is a challenging task, Currently, the electrical discharge machining (EDM) process is the optimal solution for machining such materials. Electrical discharge drilling machines find applications in various sectors such as aerospace, automobile and medicine. In this research, two different brass electrode geometries are considered: tubular electrode tool (TET) and double D tubular electrode tool (DDTET) on an SS202 work-piece. The input parameters of peak current (PI), pulse time ON (PONT), and pulse time OFF (POFFT) were varied. The output response measured and compared were material removal rate (MRR) and over cut (OC). The Taguchi technique was used to design the l16 orthogonal array (OA) experiment, and analysis of variance (ANOVA) was employed for result analysis using Minitab20 statistical software package. The results showed that the DDTET method produced significantly better MRR and OC improvements of 21.66 % and 2.28 % respectively. Additionally, a study was conducted on the formation of the recast layer (RL) and the heat affected zone (HAZ). modified electrode geometry material removal rate over cut recast layer analysis of variance modificirana geometrija elektrod stopnja odvzema materiala nadmera pretaljeni sloj ANOVA true false true Angleški jezik Slovenski jezik Neznano 2025-01-27 12:15:30 2025-01-27 12:15:35 2025-01-28 04:00:20 0000-00-00 00:00:00 2024 0 0 Str. 595-606 no. 11/12 Vol. 70 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-06-27 2024-10-04 2024-12-01 621 2536-3948 224014851 https://www.sv-jme.eu/article/experimental-investigation-on-ss202-using-tubular-and-double-d-tubular-electrode-tool-in-electrical-discharge-drilling-machining/ 1 3a2b4c69-dc9f-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198766 Pandiyan_..._Experimental.pdf Pandiyan_..._Experimental.pdf 1 43615339C9F5428FC92DF8524E41B6EF 24f4c99f15e026d8535e30def3105201f2a53e6b521c7dd47940878df399d9f2 f08be634-dc9f-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198767 Fakulteta za strojništvo Strojniški vestnik 0 0 0
