Visualization of Grinding Wheel Surface Topography for Multiple Passes of Rotary Diamond Dresser

The grinding wheel surface topography after dressing is an indicator of the effectiveness of dressing operation and, thereby, the effectiveness of grinding as a whole. During dressing, the dresser travels the grinding wheel surface several times so that the dresser grits could hit all most all points on the circumference of the grinding wheel. But the same point should not be hit several times by the dressing grits. This study describes a method and tool for visualizing the grinding wheel surface topography for multiple passes of rotary diamond dresser. Using the proposed visualization method and tool, one can determine the effectiveness of certain dressing conditions beforehand. In addition, the visualization tool can be used for optimizing the design variables of a rotary diamond dresser.
