Determination of material removal rate of an electro-discharge machine using dimensional analysis

Abstract

This paper describes the use of dimensional analysis in investigating the effects of the electrical and the physical parameters on the material removal rate of a diesinking electro-discharge machine. A brief explanation of the material removal process is presented and the factors influencing the material removal rate are identified and used in the dimensional analysis to produce a mathematical model for the material removal rate. The validity of the analysis is verified since it predicts results which are in good agreement with experimental findings.
