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

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.
