The truing and dressing of a metal-bonded diamond (MBD) wheel, in practice, are very difficult. To grind small-diameter internal cylindrical surface with MBD-wheels, an interval electrolytic in-process dressing (ELID) method was utilized. Experiments were carried out on an ordinary cylindrical grinding machine with an attached internal grinding set-up, and straight type grinding wheels of different grit sizes were used. The grinding wheels were trued, using the electrical discharge method, and the effects of electrode shapes, grinding parameters, and grit sizes were evaluated experimentally. Mirror surface grinding of different materials was carried out with a #4000 CIB-D wheel, incorporated with this interval ELID (ELID II) method.

Introduction Along with the technological advancement of ultra-precision grinding, applications and [1] requirements for precision cylindrical surfaces have increased significantly in the recent years. As a principal processing method for an internal surface, cylindrical grinding has been commonly utilized as a final operation in the production of precision components. Since grinding is usually the most costly of all manufacturing processes, considerable attempts have been focused on the analysis and optimization [2-6]of the grinding process to minimize machining time , an
