“…Tool lifetime and resistance to high working temperatures as critical requirements for producing cost-effective tool steels [ 68 , 69 ] can also be achieved by producing cheaper tool steel, compared to the high speed steel (HSS), by applying a surface treatment such as plasma nitriding, for example, and/or by depositing a hard coating. Moreover, this practice has also the advantage of improving the tribological properties of the coated tool steel [ 70 ].…”

The Critical Raw Materials (CRMs) list has been defined based on economic importance and supply risk by the European Commission. This review paper describes two issues regarding critical raw materials: the possibilities of their substitution in iron-based alloys and the use of iron-based alloys instead of other materials in order to save CRMs. This review covers strategies for saving chromium in stainless steel, substitution or lowering the amounts of carbide-forming elements (especially tungsten and vanadium) in tool steel and alternative iron-based CRM-free and low-CRM materials: austempered ductile cast iron, high-temperature alloys based on intermetallics of iron and sintered diamond tools with an iron-containing low-cobalt binder.

“…Cheung et al [3] have studied the effects of several process parameters on dam-bar (integrated circuit component) cutting tools wear, and have established relationships between punch flank wear, burr height and cutting force. Monteil et al [4] have developed a direct method to measure wear on cylindrical punch, based on selective activation technique, which allows real time quantification of process parameters influence like blanked material nature or lubrication.…”

a b s t r a c tThis work presents a combination of finite element simulations of copper alloy thin sheet blanking and a wear algorithm based on Archard formulation for abrasive wear of the punch. Firstly, a tribometer has been specifically designed to measure wear coefficient, and punch worn profiles have been extracted by means of a double-print method. Secondly, the blanking process has been simulated through the finite element method by using an elasto-plastic constitutive model and the shear failure model. Thirdly, a wear algorithm has been programmed using experimental wear data and mechanical fields computed from blanking simulation. Then, a damage criterion, namely the shear failure model, has been calibrated by an original method based on stress triaxiality analysis and shear height value measured from blanked edge profile. Finally, punch wear predictions have been discussed and compared to experimental results.

“…Hernandez et al [3] have studied the effects of tool wear on the shearing mechanism and resulting form errors. Monteil et al [4] have developed a direct method for measuring punch wear, based on selective activation technique, which allows to quantify in real time the influence of blanked material or lubrication. However, compared to other forming processes such as deep drawing [5,6] and hot forging [7], the combination of experimental and numerical methods to predict tools wear has been less investigated in blanking.…”

a b s t r a c tThis research on punch wear resulting from the blanking of copper alloy thin sheet has been conducted by means of experimental and numerical analyses. Firstly, the experimental method has consisted in measuring punch worn profiles from replicas, and secondly in obtaining the wear coefficient by using a specific tribometer. The numerical modelling of blanking process has been developed with the finite element method to compute the mechanical fields necessary to calculate wear. Thus, the Archard formulation for abrasive wear has been programmed to compute the wear depth and the resulting punch geometry. Finally the simulation results of wear prediction have been compared to experimental ones.
