Numerical simulation of powder mixed electric discharge machining (PMEDM) using finite element method
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...

متن کاملOptimization of Powder Mixed Electric Discharge Machining using ASTM A-105 Steel by Response Surface Methodology
The objective of this paper is to study the effect of the various process parameters i.e. peak current, noload voltage, pulse on time and duty cycle on response parameters by mixing silicon powder in the dielectric fluid of the Electric Discharge Machining (EDM). Response surface methodology (RSM) is used for investigating the effect on these parameters. Central composite design (CCD) is used f...
