Electrical Discharge Machining (EDM) Die Sinking, also known as sinker EDM, is a process that utilizes electrical discharges to precisely machine metals. This technique is particularly indispensable for creating intricate shapes and cavities in materials that are difficult to machine using conventional methods. The key function of EDM Die Sinking is to deliver high precision and detail in components, making it ideal for industries that require minimal tolerance, such as aerospace, automotive, and electronics.

The core components of an EDM die sinking machine include electrodes and dielectric fluids, each playing a crucial role in the machining process. Electrode materials, often made from graphite or copper, act as the tool that shapes the metal workpiece. The electrode, submerged in dielectric fluid, supports the discharge process by insulating both the electrode and workpiece, but allows spark creation at high voltage. According to research published in Applied Sciences, "EDM processes, including die sinking, rely heavily on the properties of electrodes and dielectric fluids to achieve effective material removal" (Qudeiri et al., 2020). This combination allows EDM drilling and crafting of highly detailed components without direct contact, therefore eliminating mechanical stress on the material.
