Abstract (EN): It is known that the servo reference voltage affects the material removal rate. However, its effect on the tool wear rate is not well known. In this study was used an electro-thermal model to simulate a single electrical discharge. Therefore, this numerical and experimental study not only shows the effect of servo reference voltage on the material removal rate but also on the tool wear rate. The effect of servo reference voltage on the material removal rate is multiplicative, in the generality of the cases, occurring multiple discharges, but it can also be reductive in some of them, meaning that, occurs an incomplete discharge. The effect of servo reference voltage on the tool wear rate is always reductive when the material removal rate is multiplicative and vice-versa. The numerical results agree well with experimental data. (C) 2013 The Authors. Published by Elsevier B.V.
