“…The workpiece is interchangeably referred to as materials and the tool as electrode. In details, when ignition voltage is applied between the electrodes, the breakdown of the dielectric is initiated by moving the electrode towards the workpiece [12]. This will increase the electric field in the gap until it attains the necessary value for breakdown.…”

The effect of microstructural refinement and presence of TiB particles on the electrical discharge machinability of hypoeutectic B-modified Ti-6Al-4V alloys have been studied. This has been characterized on the basis of changes in the following machining responses: material removal rate and tool wear rate. Material removal rate remains unaffected by B addition to Ti-6Al-4V because of insignificant changes in hardness and melting point of the alloy with B modification. On the other hand, microstructural refinement associated with minor amount of B addition leads to enhancement in alloy strength, and hence, tool wear rate has been found to reduce constantly with increasing the amount of B addition. Moreover, the shielding effect of TiB particles, which have higher melting temperature and hardness compared to the Ti-6Al-4V matrix, has also been found to control the wear of the tool.

“…An electric arc is produced between the workpiece and the electrode until the desired shape is obtained. The workpiece and the electrode are submerged in a dielectric environment [3], both are also electrical conductors [4]. EDM is especially efficient for machining materials with high-hardness and complex geometries [5].…”

Due to their excellent strength-to-weight ratio and corrosion and wear resistance, γ-TiAl alloys are selected for aerospace and automotive applications. Since these materials are difficult to cut and machine by conventional methods, this study performed drilling tests using Electro Discharge Machining (EDM) to compare the machinability between two different types of γ-TiAl: extruded MoCusi and ingot MoCuSi. Different electrode materials and machining parameters were tested and wear, surface hardness, roughness and integrity were analyzed. The results indicate that extruded MoCuSi is preferable over MoCuSi ingots.
