Conventional machining of titanium alloy Ti6Al4V cause high temperature and rapid wear of tool which makes him hardly suitable for machining by machine cutting. The presented experimental study was carried out on a modern wire EDM Sodick AQ327L. Three types of the wire were used. Investigated were the effects of such input parameters as the pulse width and the time between two pulses on the output parameters such as area cutting efficiency, workpiece surface roughness and wear rate of the electrode. The resulting relationships were determined using the conventional regression analysis and neural networks. The results were checked for goodness of fit.
