Modelling and analysis of the electric field for a canonical problem in EDM. (English) Zbl 0772.65082
Summary: We present two models of the electric field for a canonical problem in electric discharge machining (EDM). In particular, an analytical solution based on optimal parameter estimation is discussed, followed by a comparison with numerical solutions based on finite elements and Galerkin boundary elements. The problem is interesting because the structure of the field near the sharp asperity is a critical parameter in realistic models of the electric discharge machining process.
