Optimization of electrical discharge machining process for titanium alloy BT14 based on the solution of the heat task of moving the boundary of the phase conversion of material

The results of theoretical studies of titanium alloy machinability by electrical discharge machining based on the solution of the heat problem of moving the boundary of the phase conversion of material are presented in this article. The description of the computer program developed for solving the above-mentioned heat problem is given. The procedure of defining rational modes of electrical discharge machining of titanium alloy ВТ14 is proposed and recommendations are given for the purpose intended. The minimum heat flux density and the duration required to implement the process of electrical discharge machining of titanium alloy BT14 are determined. The dependence of the minimum pulse duration of the heat flux on the heat flux density is established at which the electrical discharge machining of titanium alloy BT14 is possible. The following is determined: the maximum pulse duration of the acting heat flux which results in the greatest removal of alloy BT14 per pulse; the effective duration of the heat flux providing the maximum efficiency of the process of electrical discharge machining of titanium alloy.
