Machining using spark is one of the widely used advanced machining methods. Surface quality and machining productivity are the two most important parameters[1]. The majority of optimization studies are in single-objective form[10][14]. However, there have also been some studies on the basis of multi-objective optimization problem[10][14]. SKD11 steel is a steel grade according to Japan's JIS standard (AISI standard named D2; DIN standard named 2379), widely used in cold fabrication with high wear resistance characteristics, good tempering permeability. SKD11 large material is used after hardening, so it is usually machined on a spark machine. This paper studies the influence of two basic parameters: voltage level (Ue); amperage (Ie) on wire cutters when machining SKD 11 material after quenching

Keywords : Processing of hardened SKD 11, machining quality on wire cutting machines, roughness and cutting productivity, influence of technological parameters (Ue; Ie) on wire cutting machines.
