9. 1 Applications It is used in Grinding Thin Sections

10. 2 Applications Grinding of High Hardness materials such as Cermates , super alloys & metal matrix composites.

11. Parameters used in EDDG WHEEL SPEED - The rotation speed of the diamond grinding wheel is essential for controlling the grinding action and material removal .. CURRENT - It affects the spark energy and material removal rate. Higher currents result in more aggressive material removal . PULSE FREQUENCY – It is the rate at which electrical discharges occurs & affects MRR and surface finish. It can be adjusted to control the spark's timing and location . DIAMOND PARTICLE SIZE – The size of the diamond particles effects the surface finishing of the work piece. The smaller the size of abrasive the better for higher surface finish
