“…The cut elements are usually subjected to further plastic working, but there are also those that are directly used in the assembly process of complex products. The blanking of the elements with a punch of flat surface has been very well presented in a number of works [3,4,5,6,7,8,9,10,11,12,13,14,15,16,17]. When punching with a flat face, the edge pressure on the sheet is uniform.…”

“…The intensity of the burr height increase depends on the speed of wear of blanking tool edges [4,5,6]. In the case of blanking thin sheets with special magnetic properties, it is important to choose the appropriate clearance, so the area of the hardened material will be the smallest [4].…”

“…Tool wear is particularly important when blanking thin sheets. The quality of the intersection surface in the blanking process is influenced by the type of punch material [5,6]. Works [4,5,6] present the influence of the punch material on its wear (tungsten carbide, M2, M3: 2).…”

Works [4,5,6] present the influence of the punch material on its wear (tungsten carbide, M2, M3: 2). Tool wear depends on the size of the clearance, punch material, and sheet material [7,8,9,10,21,22].…”

In this thesis, the results of an experimental analysis of blanking angled hooks with a punch of a sloping face in a thin steel sheet with a hardness of 55 HRC are presented. The blanking punch was made of K340 cold-work tool steel. Tests were carried out for three values of clearance, 5%, 10%, and 15% of sheet thickness. The results of the analysis of the influence of the number of cuts made by the punch on the growth of the burr at the sheet edge were presented. Moreover, the influences of the clearance on the initial values of burr (bh), deflection (Hb), and the bending radius (Rb) of the hook have been shown. The influence of the friction path on the intensity of degradation of working surfaces and the blanking edges of the punch was also demonstrated. The obtained results allow the selection of the proper clearance and new tool materials for blanking blades working in particularly difficult tribological conditions.

In this paper, we presents the results of investigations studied the cutting ability and grindability of selected high-speed steels. We analysed the effect of the austenitization temperature on the grain size, the amount of retained austenite and percentage of retained austenite in HS3-1-1 steel. Furthermore, the investigations concerned on the efficiency of the keyway broaches during the whole period of operation were carried out. It was found that the value of average roughness parameter increases together with increases in the grinding depth. The investigations also show the influence of tempering conditions on the volume of carbide phases in HS3-1-1 steel.
