Industrial electrostatics perforation improvement by power controlled discharges

The Electrical Discharge Machining (EDM) is used to drill and mechanize a variety of rigid materials that cannot be cut or shaped by typical tools because of their high hardness or complex shape. The EDM operating principle is based on the interaction between solid matter and the electronic arc discharge. The severe physical conditions around the spark are be used to mill and drill all kind of materials [1]. The electro-perforation is a particular case of the EMD which allows to make holes in permeable materials such as paper or biological membranes to generate a drilling pattern with controlled porosity for different applications[2].
