However, obtaining a good surface quality is a challenging task that depends on the effect of several process parameters and necessitates the use of non-conventional procedures. Notch shear cutting is a relatively new progressive approach in which the workpiece is indented with a notch form with a predefined notch angle and depth, and then the indented workpiece is subjected to conventional piercing. In this study, conventional piercing and notch shear cutting processes were experimentally performed on 1.4301 stainless steel sheet of 2 mm thickness. Then, finite element (FE) analyses were conducted utilizing Deform-2D software. After ensuring that the experimental and simulation works were consistent with each other, the FE analysis of notch shear cutting was carried out for three distinct notch depths (15 %, 30 %, and 60 % of the workpiece thickness) and six different notch angles (10º, 20º, 30º, 40º, 50º, and 60º). Investigations were performed on shear zone length distributions, which are direct indications of the surface quality on sheared workpieces, crack propagation angles, and required cutting loads. The best surface quality was obtained when the notch angle was set to 50º and the notch depth was set to 15 % of the workpiece thickness. It was also observed that notch angle and notch depth had a certain level of influence on required cutting load. metal cutting notch cutting piercing surface quality luknjanje izsekovanje s predzarezovanjem rezalne sile kot zareze globina zareze oblikovanje srha strižna cona kakovost površine true false true Angleški jezik Slovenski jezik Članek v reviji 2023-09-01 08:44:17 2023-09-01 08:44:18 2023-09-02 03:46:37 0000-00-00 00:00:00 2023 0 0 Str. 326-338 no. 7/8 Vol. 69 Jul./Aug. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.9:519.61 0039-2480 10.5545/sv-jme.2023.541 159343363 Emre_Engin_..._-_Finite_element_analysis_of_notch_depth_and_angle_in_notch_shear_cutting_of_stainless-steel_sheet.pdf Emre_Engin_..._-_Finite_element_analysis_of_notch_depth_and_angle_in_notch_shear_cutting_of_stainless-steel_sheet.pdf 1 F08438549494CBF92675FA00CAAB3BC6 056794909af86d035f8ab1312b20c1e31d98a1b20b737d6b7c2122885bb6a897 20fce5ae-4893-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173308 https://www.sv-jme.eu/sl/article/fem-investigation-of-notch-depth-and-angle-in-notch-shear-cutting-of-stainless-steel-sheets/ 1 fc16eba2-4892-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173306 Fakulteta za strojništvo Strojniški vestnik 0 0 0
