The application of electrical spark discharges for edge honing has been demonstrated
The counterface material plays a critical role in the geometry of the generated edge
Edge hones generated by electro-erosion honing significantly improved the life of ground tools
Electro-erosion honing corresponds to robust edge geometry generation as compared to conventional processes
