In the present paper, an axisymmetric two-dimensional model for powder mixed electric discharge machining (PMEDM) has been developed using the finite element method (FEM). The model utilizes the several important aspects such as temperaturesensitive material properties, shape and size of heat source (Gaussian heat distribution), percentage distribution of heat among tool, workpiece and dielectr...

Abstract The addition of powders in electrical discharge machining (EDM) reduces the breakdown strength liquid dielectric, thereby enhancing occurrence early spark, and aids machinability. Challenges occur sustainability powder mixed (PMEDM) process terms homogeneity powder-dielectric mixture adverse effects these on impellor pump, maintaining concentration powder–dielectric for a wide range at...

Background: Electrical Discharge Machining (EDM) is a well-established non-conventional machining process for the machining of electrically conductive and difficult-to-machine materials. But its applications are limited because of the slow machining rate and poor surface finish. Powder mixed EDM (PMEDM) is unitary of the recent progresses in the EDM process in which powder particles mixed in th...
