Machining using spark is one of the widely
used advanced machining methods. Surface quality and
machining productivity are the two most important
parameters. The majority of optimization studies are
in single-objective form. However, there have
also been some studies on the basis of multi-objective
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
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.
