A comparison between micro milling pure copper and

Nov 01, 2019 As a work tool for EDM, electrodes made of pure copper (Cu) and tungsten reinforced copper (WCu) are commonly used. The quality and reliability of the eroded shapes are determined to a high extent by the quality of the electrode deployed. For this reason, micro milling is a crucial factor in the process chain and its impacts have to be evaluated.

Electrical Discharge Machining (EDM) : Principle, Working

Sep 06, 2021 Electrical discharge machining (EDM) is a process of removing material by exposing it to repetitive controlled electrical discharges. It is suitable for thermoelectric phenomena. When a discharge occurs between the electrode/wire and the workpiece, heat energy is generated on the workpiece. This leads to the removal of the material layer.

Material Removal Rate, Electrode Wear Rate, and

Electrical discharge machining is one of the earliest nontraditional machining, extensively used in industry for processing of parts having unusual profiles with reasonable precision. In the present work, an attempt has been made to model material removal rate, electrode wear rate, and surface roughness through response surface methodology in a die sinking EDM process.
