Abstract

This paper is focused on the effect of generator’s parameters on the stability of WEDM process that is expressed by the length of time of cutting until the wire electrode breaks. This paper provides an overview of the current research articles dealing with the causes of the wire electrode’s rupture and the options of control and regulation of the process. The aim was to clarify the impact of input parameters to the cutting process, and to find those parameters making the process as fast as possible and stable. The experiment was performed on the machine of Agie Charmilles Robofil 310. As input factors were selected pulse width, time between two pulses, servo voltage, pulse current, short pulse time and frequency. Due to the fact that it is necessary to assess the impact of several input parameters, Taguchi experimental design was selected. L27 matrix was used. The Analysis of Variance (ANOVA) was used for evaluation.
