Wire electrical discharge machining (WEDM) is non conventional technology in which the electrical discharges occurring between the wire electrode and workpiece allow to machine difficult to cut material. The shape accuracy of cut high parts is one of the major limitations of WEDM. Establishing favorable machining conditions for the required dimensional accuracy plays a key role in the process. Response surface methodology (RSM) was used to build empirical models on the influence of the discharge energy E, workpiece height H and wire tension Fn on the surface flatness deviation W and material removal rate MRR during the machining of tool steel X165CRV12. Developed models can be used in the WEDM process as a guideline for the selection of parameters to achieve the desired surface flatness deviation W and material removal rate MRR in industrial applications.
