Abstract In the manfacture of structural ceramic components, it has been well documented that the grinding costs can be as high as 90% of the total cost. Grinding costs of ceramics can be reduced by maximizing the material removal rates (MRR). A novel grinding technology that incorporates in-process dressing of metal bonded superabrasive …

Further, an electrolytic in-process dressing was introduced to perform a mirror grinding with 0.13-0.4-μm-size diamond grains by Ohmori and Nakagawa (1995). Through a minimizing hydrodynamic pressure, the ultra-precision grinding with 10-μm-size diamond grains was also realized by Lee et al. (2004).

Periodic dressing is essential to minimize the above problems and this makes the grinding process very tedious. In 1985, Murata et al. introduced electrolytic in-process dressing (ELID) to grind ceramics with metal-bonded diamond wheels of grit size less than #400, and found the method to be efficient for grinding hard and brittle materials.
